Air Purifier Selection Guide that everyone should know~

A hotel is a place with a large flow of people, and the air environment of the hotel rooms is complicated. With the improvement of the hotel accommodation environment, whether the hotel room air environment is fresh and healthy has become an important factor affecting the hotel guest experience.
More and more hotels are beginning to deploy the best cheap air purifiers for allergies in their rooms, but the quality and purification effects of air purifiers on the market are mixed. Conventional home air purifiers often cannot meet the complex air purification requirements of hotel rooms.
So, how do you choose an air purifier that can be highly purified? Before buying a suitable air purifier, first, understand what is the knowledge of the best air purifier for mold and allergies?
The working principle of most air purifiers is to use the fan to extract air, obtain a certain wind pressure through the fan, and then pass through the heavy filter to remove the particulate matter, harmful gases and bacteria in the air, and finally get clean air;
The air purifier can be selected to select the most suitable air purifier with the CADR and CMM values ​​of the air purifier as a reference. The CADR value, the Chinese name is the clean air output ratio, and the national standard unit is m3/h. From a literal point of view, the higher the CADR value, the better the purification effect. The approximate applicable area of ​​the purifier can be measured by the CADR value.
The air purifier market has been very confusing for a long time because there is no clear standard. The new national standard clearly stipulates the key parameters of the air purifier (the most important one is CADR). After the official implementation, most manufacturers will issue test reports according to the new national standard, but they are not enforced, and there is no designated detection mechanism for the purifier. . Therefore, a more authoritative third-party testing agency is required to give a credible test report.
The CADR was developed by AHAM (American Association of Home Appliance Manufacturers), so the value of the AHAM-certified CADR value is the most reliable. However, domestic air purifiers are too troublesome to detect in the United States, so the current domestic industry is more authoritative testing institutions such as China Household Appliances Testing Institute, Shanghai Environmental Protection Product Quality Supervision and Inspection Station, and Guangzhou Industrial Microbiology Testing Center.
The higher the CADR value is, the better the performance is.
The CADR value is affected by two factors, one is the primary purification rate and the other is the air volume.
The former represents how clean the air can be filtered inside the purifier, while the latter means that a fixed volume of air can be filtered several times in a certain period of time.
The ideal state is to filter the air almost every time and then filter it many times in a short period of time. But this is actually a contradiction: the higher the purification rate, the higher the filter grade of the purifier, the denser the filter is placed, and the thicker the filter, which makes the resistance of the air through the filter much larger. , resulting in a significant drop in air volume.
Therefore, the middle and low-end purifiers generally “quantify”, that is, use high air volume and more cycles to compensate for the lack of single purification efficiency. The side effect is that the filter life is very low, usually 3-6 months. replace.
The high-end purifier is “stable”, with a focus on the pursuit of ultra-high purification rate and longer filter life.
The CADR values ​​of PM2.5 and formaldehyde are separate
The CADR value is how many cubic meters of clean air can be output per hour. It should be noted that the clean air here refers to the air that does not contain certain harmful substances. For example, clean air without formaldehyde can be expressed by [CADR formaldehyde]. As for PM2.5, it does not matter. Similarly, clean air without particles is represented by [CADR particles], as for whether there is formaldehyde in it. It doesn’t matter. Therefore, there are two types of CADR specified in the new national standard for air purifiers: CADR (PM2.5, dust, etc.) and formaldehyde CADR. The two parameters represent two aspects, which are also presented separately in the test report.
What are the standards for an excellent air purifier?
For the air purifier, although the CADR value can directly reflect the purifying effect of the purifier, which machine filter can be used for a longer time, the working noise is loud, and what kind of working principle is used is also a good purifier. It should be noted at the time.
1 long-term effective
CCM (cumulative purification, in mg) is another important parameter in the new national standard for air purifiers, which specifies the amount of particulate matter or formaldehyde that can be eliminated before the filter is “discarded”. Like CADR values, CCM is also divided into particulate CCM and formaldehyde CCM, and each CCM is divided into 4 grades. The larger the CCM value, the better, indicating the longer the filter life.
2 have a clear authority inspection report
This is the strongest evidence to prove that a purifier is excellent. The published report must show the CADR and CCM test data for particulate matter and formaldehyde, respectively. The key information that should be included in the report meeting the new national standard is: particulate CADR value, formaldehyde CADR value, and particulate matter CCM grade.
3 running noise is small
A good purifier with a minimum working noise of 25-35db (and the higher the CADR of the minimum file is better), the maximum working noise cannot exceed 70db. High CADR values ​​are inseparable from high air volumes, but the greater the air volume, the greater the noise. A good purifier can reduce noise by using a better fan and a more reasonable internal air duct, which makes us more comfortable.
The minimum gear of the purifier is usually used when we are resting. At this time, the purifier needs to be quiet. 25-35db is the equivalent of the sound we hear when we are quiet at night, and it hardly affects our rest. The highest 70db is the national new national standard. Any qualified household air purifier, no matter how high the CADR value, should not exceed it.
4PM2.5 numerical real-time display
Many air purifiers cannot display specific values, only roughly use different colors or use “excellent, good, medium, and poor” to display, and look ambiguous. An excellent purifier can display the value of PM2.5 in the air in real time so that we can see the changes in indoor air quality very intuitively.
5 remote control
The purifier with remote control allows us to master the room air quality in real-time. When the air quality is not good, it can be driven to the maximum position before returning to the room. When you return to the room, the air quality has become better, you can adjust to the gear with less air volume, and the working noise is smaller.

Project standards detected by the air purifier quality inspection report

Air purifiers, also known as “air cleaners“, air purifiers, purifiers, are capable of adsorbing, decomposing or converting various air pollutants (generally including PM2.5, dust, pollen, odor, formaldehyde, etc.). , bacteria, allergens, etc., products that effectively improve air cleanliness, mainly divided into household, commercial, industrial, and building. In order to ensure the scientific and fairness of the inspection capability and inspection work of the third-party inspection agency, the relevant state departments have granted the measurement certification certificate after confirming the measurement capability of the inspection agency and allowed them to stamp the CMA chapter on the inspection report. Take a look at the project standards detected by the air purifier quality inspection report. Items detected by the air purifier quality inspection report:

1. Test: The safety of the air purifier includes key tests on electronic components, internal fans, internal and external power lines, air inlets and outlets, and leakage, moisture, and electrical strength. These tests are tested by professionals in the national quality supervision department. Safety testing is divided into three levels: first-class safety, second-level general, and third-level qualified.

2, CADR value detection includes PM2.5 purification and formaldehyde, stupid and other purification effects. The energy-saving effect is divided into five levels of energy efficiency according to the energy-saving efficiency of household appliances under the new national standard. The first-level power consumption is the lowest, and fifth-level power consumption is the highest. At the same time, the same gear function, the power consumption of each product is detected.

The detection standard of solid pollutants (>0.3μm particles) is: GB/T 18801-2015 air purifier

The standards tested by the air purifier quality inspection report:

1. The performance purification capability reflects the actual working capacity of the purifier, called the clean air volume (CADR), which is characterized by the volume of air that can be purified per unit time. The unit is cubic meters per hour.

Requirements: (1) The measured value of the clean air of the purifier for the particulate matter should not be less than 90% of the nominal value;

(2) Same as above, the measured value of the clean air of the purifier for gaseous pollutants should not be less than 90% of the nominal value;

(3) Purification durability. The length of time that the purifier can be used is a parameter and indicator that consumers are very concerned about, and the length of use can be measured by the number of pollutants that the purifier filter can absorb, and is expressed by the cumulative purification amount (CCM). Mg, mg.

There are many ways to effectively clean the air.

There are many types of best inexpensive air purifier on the market today, and the effects are different, but the principle is the same, all the air is filtered, but some bacteria after filtration are still not killed. If the bacteria continue to multiply on the filter, it will become a source of pollution.
“The filter capacity of the best inexpensive HEPA air purifier is limited. In the case of serious air pollution, the filter will be saturated after a few months, and it needs to be cleaned or replaced regularly.” The relevant person in charge of the Municipal CDC introduced If it is not cleaned regularly, the bacteria will multiply on the accumulated dust when the humidity is right. At this time, the air purifier is not only ineffective but becomes a source of pollution.
In addition, the person in charge also suggested that although environmental problems have ignited the air purifier market because such products are not developed in China for a long time, consumers should calmly think when they choose. “If the public feels that it is really necessary, it is ok to buy a high-powered one. There is no need to buy four or five units or even more at home. This is an increase in the area of ​​purification. The effect is the same.” Wu Changzhu also said that it is regular. Clean the room, keep the room ventilated, when the air quality is good, open the window to change the air, the air pollution is serious, the morning and evening peaks open fewer windows, and the green plants such as spider plants are placed indoors, which also help to purify the air, and is simple, Affordable and easy to operate.

In case of “smog” air purifier is hot, the actual purification function needs to be improved

Shanghai Renshoutang Sinopharm on Beihong Road and Yifeng Pharmacy on Tianshan West Road… The reporter visited a number of pharmacies in Shanghai yesterday and found that a variety of masks were placed in the conspicuous window, including children’s masks and adult daily masks. And the most preventive PM2.5 masks. The reporter noted that among these mask products, the price of one-time anti-mite masks (three bags of one bag) is about 25-30 yuan, and the price of non-disposable moth masks is more expensive, basically at around 40 yuan.
    “Many companies concentrate on ordering masks for employees, and corporate orders are increasing. The purchase volume of individual customers is relatively stable, but compared with a few years ago, the increase in mask sales in the same period of this year is very obvious.” A pharmacy salesperson told reporters that As the smog enters a high incidence period, the sales of FITs in masks continue to increase. In addition to a physical business, the words “must mask” are entered on the web platform, and there are hundreds of products for sale. In the official flagship store of 3M, a 20-piece N95 headband anti-fog mask with a price of 138 yuan, the total sales exceeded 100,000, the monthly sales broke 5,000 boxes, and the other 25 pieces were sold, sold and sold. The monthly sales of the “Dust-proof smog PM2.5 mask” with a price of 158 yuan reached more than 7,000 boxes.
In addition to the anti-mite mask, the top 5 best air purifiers have become the choice of “defense” after New Year’s Day. In the Changle Road store of Yongle Electric, the reporter noticed that all major brands will have air purifiers with the effect of removing cockroaches in a conspicuous position. The reporter noticed that the price of the air purifier with the main function of removing the cockroach is in the range of 2999-3599 yuan, while the price of the multifunctional air purifier is basically above 4999 yuan. In terms of purification function, most models of particulate matter removal and formaldehyde purification energy efficiency levels are shown as high efficiency.
It is worth noting that China’s first top 10 best air purifiers China environmental labeling standard has been implemented since January 1 this year. After the implementation of the standard, consumers can use the Chinese environmental label on the purifier product as one of the important basis for purchasing the product. When the salesperson introduced the product to the reporter, he pointed out that the sign was posted on the shelf purifier in the mall. The relevant person in charge of Suning Shanghai disclosed to reporters that since the New Year’s Day, the sales of air purifiers in Shencheng Suning’s physical stores have increased by 170% year-on-year and by 250%.
The sales staff told reporters that in addition to the purchase of individual customers, the orders of enterprises during the New Year’s Day increased significantly. “Business procurement is used for air purification in offices, and most of them are for the health of employees.”
Actual purification function needs to be improved
The demand for anti-mite products has surged, but the efficacy of anti-mite products has actually been improved.
The Municipal Consumer Protection Committee disclosed that of the 20 mainstream brand air purifier products, 12 were purchased in large department stores, and 8 were purchased on e-commerce platforms, with prices ranging from 699 yuan to 18,600 yuan per unit. The comparative test was carried out for product promotion and consumer-focused particulate matter purification functions (clean air volume, applicable area, PM2.5, 0.1μm to 0.2μm particulate matter), gaseous pollutant purification function (formaldehyde, sulfur dioxide) and other projects.
The results showed that among the 20 samples, the purification ability of formaldehyde and sulfur dioxide was quite different. The nominal value of some enterprise product functions differed from the measured values. Among them, 20 samples of PM2.5 clean air volume highest and lowest value, the measured difference is more than 7 times. The maximum value of the clean air and the minimum value of the particle size of 20 samples from 0.1 μm to 0.2 μm are also more than 7 times. 20 samples of sulfur dioxide clean air, the highest value and the lowest value difference of 27 times.
According to another report, 11 samples of the nominal formaldehyde clean air quantity value are found in the new national standard of the air purifier, “the measured value of the clean air volume should not be less than 90% of the nominal value”, and the nominal Panasonic Environmental System is found. A “Panasonic” air sterilizer produced by the company is not consistent with the measured values ​​and does not meet the standard requirements.
In addition, the nominal value of some enterprise product functions is quite different from the measured value, such as an “Olansi” air purifier, which is nominally produced by Zhejiang Wuyi Youdun Electric Co., Ltd., and the measured applicable area is much smaller than the standard value.
Selection and use should be properly selected
The Municipal Consumer Protection Committee pointed out that consumers should purchase air purifier products through formal channels, avoid buying “three no” products and ensure the quality and after-sales of products. Purchasing air purifiers according to their actual needs, such as smog-prone areas can focus on PM2.5 and other products with strong purification ability of particulate matter, the indoor new decoration can focus on formaldehyde and toluene and other volatile organic compounds purification products. Attention should be paid to the particulate clean air volume (CADR) and the applicable area of ​​the air purifier, which are directly proportional to each other. Do not leave the applicable area and look at the size of the CADR. At least the air purifier with a product area not less than the actual use area should be selected.
In addition, consumers can also focus on purifying energy efficiency levels. Air purifiers are usually used continuously for a long time. The energy efficiency rating is an important indicator to measure the purifying performance and power consumption of the air purifier. The higher the level, the more energy saving. Pay attention to the inspection and verification report. It is recommended that consumers ask the manufacturer to provide a third-party inspection agency test report with the “CMA” mark when purchasing, to confirm that the measured values, test methods and product promotion of each indicator are consistent, and focus on Rationality and effectiveness of the standards and test methods.

Selecting an air purifier requires attention to different technologies and different functions.

Posted on by

Selecting an air purifier requires attention to different technologies and different functions.

At present, there are many air purifier products on the market, and the technologies used are various. Although most purifiers have filter designs, not every purifier with filters is a filter purifier. Consumers, who should choose which technology purifier to achieve the purpose you want? This has to first understand the current mainstream purifier technology!
Filtration type is a relatively common purifier technology. Its working principle is to suck indoor air into the purifier through the air inlet, and absorb the corresponding harmful gases and substances in the air through multiple layers of different functions, and then pass through the air outlet. The indoor air is purified by circulating the purified air. The energy efficiency of this type of purifier is the first condition of the filter.
At present, there are many purifier products using HEPA filters and activated carbon filters, which can kill harmful gases and substances such as tiny particles, formaldehyde, xylene, etc., but the screens are relatively short, generally poor in air quality. In this case, the life of the activated carbon filter will last for about 6-12 months depending on the length of use per day. At that time, the user needs to replace the new filter, otherwise, the purifier will not have the effect.
Electrostatic purifier
Unlike the filter purifier, the electrostatic purifier mainly relies on the high-voltage ionized particles inside the purifier, so that it is adsorbed after being charged. Generally, compared with the filter purifier, the safety factor of the electrostatic purifier is required. The design of the lower and electrostatic type purifier dust collectors is generally sharp, and it is particularly easy to injure during the cleaning process. Therefore, when purchasing such purifiers, you must look for the brand, purchase qualified products, and clean up. Be especially careful!
Negative ion purifier
The negative ion purifier mainly generates negative ions through the negative ion device, so that the negative ions react with harmful substances and harmful gases in the air, thereby purifying the air. Negative ion purifiers will produce unnecessary substances in the process of use – ozone, it is known that a certain concentration of ozone is required in our living environment, but if the ozone concentration is too high, it will seriously endanger our health, so Also pay attention when purchasing such products. It is best to choose a regular brand of products in the formal channel. You can also simply smell it when you buy it. If the machine has a big taste after running, you should pay attention to this. Whether the index of ozone production of products is within a reasonable range.
Need to be especially reminded that if you have a history of allergies or allergies to unknown sources, then it is best not to choose a negative ion purifier, so as not to aggravate allergic symptoms in the process of purifying the air.
Photocatalyst purifier
Photocatalyst-type purifiers do not absorb harmful substances. They use photocatalysts to catalyze harmful substances and gases: they produce catalytic degradation through the action of ultraviolet rays, harmfully degrade harmful toxic substances in the air and kill a variety of bacteria, and also bacteria. The harmful substances in the process are decomposed and harmlessly treated, and have certain deodorization, anti-fouling, and purification capabilities.
Since the photocatalyst purifier must function as an isomorphic UV light, this product must be placed in a position where it can directly touch the light, and it cannot be blocked by anything in any form, otherwise, it will not be purified.
From the above introduction of various purifier technologies, we can probably classify: filter purifiers are the most common, relatively less demanding for placement, but the filter screen needs to be replaced regularly, and the cost is relatively high;
Electrostatic purifiers are basically one-time inputs, but electrostatic precipitators have relatively high relative risk factors and are not suitable for families with children and the elderly to prevent accidents;
Anion-type purifier products will release ozone while purifying harmful substances in the air. When the amount of ozone released exceeds the standard, it will cause harm to the body, and the allergic group should be used with caution;
Photocatalyst purifiers are relatively green and environmentally friendly, but they require high levels of UV light and require long-term exposure to light, so some dark, poorly lit spaces are not suitable for use with such purifiers.

Portable air purifier function class question and answer encyclopedia

Posted on by

Portable air purifier function class question and answer encyclopedia

1. What is the function of the “portable air purifier” (what is the use)?
It mainly produces a large number of negative oxygen ions, which can effectively remove PM2.5 small particles in the air and eliminate second-hand smoke. At the same time, negative ions have the effect of physiotherapy on the human body, which can effectively improve the sub-health of the human body and promote blood circulation.
2. Why is the “portable air purifier” resistant to PM2.5?
The “portable air purifier” works by mimicking the impact of the natural waterfall’s water flow, and the rainy day lightning ionizes the air, producing a large number of negative ions. The negative ions themselves have the function of electrostatic dust collection, which can very quickly make the PM2.5 such a naked eye. Small particles that are not visible, evolve into large particles and fall quickly to clean the air around you.
3. What is the difference between a “portable air purifier” and a large air purifier at home?
The portable air purifier belongs to the negative ion air purifier. It can purify the air like the large purifier. The large one is for the indoor, and the “electronic mask” is for the personal space. Relative to the space limitations of large products, “electronic masks” can be used in a variety of places, and negative ions are only effective when used at close range.
4. What advantages does the “portable air purifier” have compared to similar small purifiers?
First of all, the product itself has a stable performance and a good purification effect. Secondly, we have strong professionalism. We have been independently developing and producing since the 1980s, and have cooperated with many big brands, such as Haier. Beautiful, Whirlpool, Unilever and so on. Then, we also have our own brand, and also join forces with strength. Moreover, it can be said that at present, similar products in domestic or foreign markets are basically no smaller and more beautiful than our products, and high-end fashion effects are good.
5. How much area can the “portable air purifier” purify?
The effective purification area of ​​the “portable air purifier” is 1m3 (cubic meters), but this 1m3 (cubic meter) is movable and can be used for much space. Portable air purifier function class question and answer encyclopedia
6, “portable air purifier” product is so small, how much dust can be sucked?
The principle of “electronic mask” is not the air filtration of the conventional purifier, which sucks the dirty air into the machine. Instead, it uses ionic electrostatic dust collection to concentrate the tiny particles in the air into PM20 or larger particles. It quickly fell to the ground.
7. If these large particles have not fallen to the ground, they will be sucked into the body. Will it be worse?
No, now the news media are reporting that the small particles below PM2.5 are harmful to the human body because of the small particles such as PM2.5, unlike large particles that are metabolized by the body and immune organs (such as the nasal cavity). If it is blocked, it will be directly inhaled into the alveoli, causing damage to the lungs and respiratory tract; now portable air purifiers convert small particles into large particles, even if a small part is inhaled into the nasal cavity, it will be blocked by the nasal cavity or brought out by saliva. in vivo.
8. Does the “portable air purifier” produce negative ions while generating ozone?
The core technology of “portable air purifier” is a negative ion. The product strictly controls the generation of ozone. The ozone can only measure 0.01ppm under the distance of 0, which is 15 times lower than the national safety standard (national safety standard 0.15PPM). Less than 10 times the international safety (international safety concentration value of 0.1PPM), almost the lowest limit value of the ozone detector can be detected routinely; the ozone concentration of the product 30cm (cm) (breathing part) is 0ppm.
9. I seem to smell the smell of ozone?
The range of ozone concentrations that the human body can smell is in the range of 0.01 to 0.02 PPM (parts per million). The sensitivity of each person’s sense of smell is not the same, but this value is far less than 15 times the national safety standard (national safety standard 0.15PPM), please feel free to use. And we have relevant test reports for ozone.
10. Does the “portable air purifier” have radiation?
“Electronic mask” produces a large number of negative ions, which can effectively neutralize the positive electric radiation generated by household appliances (such as refrigerators, TVs, air conditioners, computers, etc.), avoiding the damage caused by the positive electric radiation of the appliances. In a closed air-conditioned room, the effect is even more obvious. Portable air purifier function class question and answer encyclopedia
11. What is the physiotherapy effect of the “portable air purifier”?
(1) improve lung function,
(2) promote metabolism,
(3) Enhance disease resistance,
(4) Improve sleep,
(5) Strengthen the moisturizing of the hair.
12. Why can the “portable air purifier” improve lung function?
The “portable air purifier” produces a large number of negative oxygen ions. When the human body inhales and carries negative ions, the lungs can increase oxygen absorption by 20% and discharge 14.5% of carbon dioxide.
13. Why does “portable air purifier” promote metabolism?
“Portable air purifiers” produce a lot of negative ions, negative ions can activate a variety of enzymes in the body, promote metabolism 14. Why can “portable air purifiers” enhance disease resistance?
The “portable air purifier” produces a large number of negative ions, which can change the body’s ability to respond, activate the function of the reticuloendothelial system, and enhance the body’s immunity.
15. Why can the “portable air purifier” improve sleep?
“Portable air purifier” produces a large number of negative ions, which can promote blood circulation, reduce stress, and achieve the effect of soothing and relaxing.
16. Why does the “portable air purifier” enhance the moisturizing of the hair?
The “portable air purifier” produces a large number of negative ions. Generally, the surface of the hair is scattered with scales. Negative ions can reproduce the scales of the hair surface to make the hair look shinier and neutralize the hair. Static electricity prevents hair from splitting
17. Why can “negative ions” achieve the effect of physical therapy?
First of all, the electrical activity of the body tissue needs to be continuously supplemented by negative ions. Once the organism is not supplemented by negative ions, it will affect normal physiological activities, resulting in chest tightness, dizziness, and even illness. Secondly, since the virus that attacks human cells usually has a negative charge, if the human cells also carry a negative charge, they will be repelled by the same sex. The virus loses its ability to attack live cells. Finally, negative ions can also enter the lungs through breathing, and through direct stimulation of various tissues of the human body, as well as the interaction between nerve reflexes and body fluids, produce a neutralizing physiological health effect on the human body.
18. Is the negative ion produced by the “portable air purifier” the same as the negative ion in nature?
Yes, the “portable air purifier” mimics the impact of the natural waterfall’s water flow, and the rainy day lightning ionizes the air, producing a large number of negative ions, but it is constantly being released, without the need to feel in a specific environment or a specific attempt. To pure negative ions.
19. How many negative ions are good for the human body?
When the amount of negative ions in nature reaches 100,000 to 500,000 per square, the human body has the ability to naturally repair and natural immunity. When used, let the negative ions enrich the area around your body and have a natural negative ion amount. The most important thing is regular work, reasonable exercise, a balanced diet, and a good mood. Negative ion purifiers are like tonics in life, properly conditioning the body and achieving health care.
20. Is the negative ion as much as possible?
No, only the negative ions at close range are effective. The negative ions themselves have a weak period. If the ions themselves are not absorbed, they will be neutralized by small particles in the air after a few seconds, so the negative ions near the air outlet. The quantity is the largest. The farther the distance is, the worse the effect is. The conventional large purifier has negative ions, but the machine itself is far away from people. Negative ions are difficult to communicate to the user and will disappear passively. Therefore, the amount of ions is large. Not useful, only valid at close range.
21, how to detect the negative ions generated by the “portable air purifier”, how do I know if it is effective?
Test 1: Use two transparent glass cups (transparent, smooth, good visibility), use the common cigarettes in the market, spit in a thick cup of second-hand smoke in two cups, cover one of the cups full of smoke at work. On the product, about 10 seconds, directly see the contrast effect.
Test 2: It can be close to the product air outlet, and the product under the nose is perceived to have a weak ion wind in the absence of a fan, and there is a faint freshness. Test 3: Taobao has about 200 yuan of testing equipment, which can directly detect negative ion concentration. (Involving additional fees, not recommended)
22. There are 2 million negative ions in the portable air purifier. Is it that after releasing 2 million negative ions?
No, the machine is more than 2 million negative ions per cubic centimeter per second. It is constantly being released and will not be released.
23. When is it better to use a “portable air purifier”?
Going to work, shopping, exhibiting, traveling, subway, bus, home, sleeping, etc.
24. Is it that I can’t smell a little bit of smoke after I use the “portable air purifier”?
No, the electronic mask can effectively reduce the inhalation of secondhand smoke, but it cannot completely solve the inhalation of secondhand smoke. Especially when several people smoke together, the purification efficiency of the product is not proportional to the manufacturer of secondhand smoke. The removal of second-hand smoke can effectively reduce the inhalation of second-hand smoke.
25. After I use the “portable air purifier”, can I block the bad breath of the other party?
No, this product is a product that removes small particles. If it is not an odor-prone product, if you need to solve the bad breath problem, please let the other person chew the gum.
26. Can I use the “portable air purifier” to get formaldehyde?
With the effect of removing formaldehyde, negative ions can decompose formaldehyde to make it carbon dioxide and water by ionization, but this is not the main function of “portable air purifier”.

The air purifier can detect and control indoor air and formaldehyde pollution, bringing fresh air to our interior.
Which includes
1) Settling particles in the air to effectively settle various inhalable suspended particles in the air such as dust, coal dust, smoke, fiber impurities, shavings, pollen, etc., to avoid causing allergic diseases, eye diseases, and other diseases.
2) Remove microorganisms and pollutants from the air, effectively kill and destroy bacteria and viruses in the air and on the surface of objects, and remove dead dandruff and pollen from the air to reduce the spread of diseases in the air.
3) Effectively eliminate odor, effectively remove the strange smell and polluted air emitted from chemicals, animals, tobacco, oil smoke, cooking, decoration, garbage, etc., and replace indoor gas continuously for 24 hours to ensure a virtuous circulation of indoor air.
4) Rapidly neutralize chemical gases, effectively neutralize harmful gases emitted from volatile organic compounds, formaldehyde, benzene, insecticides, aerosol hydrocarbons, and paints, while at the same time reducing the discomfort caused by inhaling harmful gases.
So, can the air purifier really eliminate pm2.5?
Air purifiers have become a must-have home appliance for many families. They have a small role in indoor air purification. They can detect and filter PM2.5 in the air and effectively protect the family’s respiratory health. In the smog weather, the indoor anti-mite air purifier can not be less.
Is the air purifier effective for removing formaldehyde?
First of all, we must understand that formaldehyde is produced by decoration and raw materials, and it cannot be removed for a long time. To solve the problem of formaldehyde permanently, it is necessary to remove the pollution source of the decoration or raw materials from the source. Otherwise, it can only be treated by formaldehyde, but if the formaldehyde exceeds the standard, then the treatment can not be completed. The air purifier is an auxiliary means, it is recommended to open 24 hours, which has a certain elimination effect on formaldehyde.
So what is the best way to remove air purifiers?
Most of the air purifiers are composed of HEPA filter and activated carbon filter. HEPA is mainly used to purify solid pollutants such as dust and PM2.5. The activated carbon filter is mainly used to adsorb volatile gases such as formaldehyde and odor.
There are two necessary conditions for indoor air quality to meet certain cleanliness standards.
First, it must be ensured that the indoor air reaches a certain number of air changes, that is, the fan built in the cleaner has a certain amount of air.
Second, the purification efficiency of the cleaner must be relatively high. Clean Air Volume (CADR) is the physical quantity that quantifies the two necessary conditions above the cleaner.
In general, the larger the CADR value, the higher the purification efficiency of the purifier. That is the clean air output ratio, which directly affects the purification efficiency. The higher the CADR value, the higher the purification efficiency of the purifier and the larger the applicable area. It can be seen that CADR is an important indicator to measure the excellence of an air purifier, but note that this is not the only or dominant indicator.
What should I pay attention to when purchasing an air purifier?
The brand, function, performance, design, and price of the air purifier are very different and dazzling. Consumers are advised to purchase products according to their actual needs, not as many features as possible. For example, for consumers who need to protect PM2.5, it is recommended to choose an air purifier with an outstanding PM2.5 purification capability. Newly renovated homes can focus on air purifiers that have outstanding formaldehyde and toluene capabilities.
At the same time, when purchasing, try to choose a big brand, the quality will be more secure.

Strong purification ability plus small details of a warm heart. This is the quality of the air purifier.

Strong purification ability plus small details of a warm heart. This is the quality of the air purifier.

It is very simple to improve the air quality in a room, and an air purifier is enough. But picking a good air purifier is not easy. Of course, the easiest way is to look at its CADR value. The CADR value refers to the amount of clean air. It refers to the total amount of clean air output per unit time filtered by the purifier. The unit is m3/h, including the particulate matter CADR and formaldehyde CADR. The higher the CADR value, the better his purification ability.
On this basis, I think Olansi air purifier is very good, its CADR value is between 601 and 800, formaldehyde CADR value is up to 400, and the CADR value of particulate matter is up to 710, which is a very strong purification ability. It is.
Not only the purification ability is strong, but Olansi also has a very high standard for purification. In general, most air purifiers set the standard for formaldehyde purification to be 0.1mg/m3 in Europe, but as can be seen from the above figure, Although the European standard is low, the formaldehyde under this concentration will still cause damage to the human body, while the purification standard of Olansi is 0.01mg/m3, which is only 1/10 of the European standard. It is possible to reduce, greatly reducing the impact of indoor formaldehyde on the human body.
Light has a high standard, but if it is not available or the purification speed is slow, it is not very useful. The Olansi air purifier also achieves rapid purification on the basis of high standards. In the room of 49-85m2, it can reduce the formaldehyde concentration to 0.01mg/m3 in 18 minutes or so.
It is important to buy an air purifier to see its purification ability, but it is not absolute. It is also convenient to choose an air purifier.
As an established manufacturer of household appliances, Olansi is very careful in designing its products and will be comfortable to use. First look at the display aspect, there is a circular display on the front of the fuselage to display three kinds of (PM2.5, harmful gases, allergens) pollutant status, purification mode status, wind size and other information, considering the air before The status of the rotation in turn is not concise and clear, Olansi will display the screen to increase the display of this information. Outside the screen is a four-color ring light that symbolizes indoor air quality. Blue indicates good air quality, purple is average, pink is poor, and red indicates poor air quality.

The display aspect has been considered so meticulously, and of course, the input into the experience will be more. Needless to say, the most common intelligent voice control, the Olansi can be switched by the Jiangyin smart speaker. Of course, you can also download the Xiaojingyu APP for remote control. You can view the air quality in your home on the mobile phone to control the operation of the AC6678. You can also check the filter life and replace it through the APP.
A warm heart is not only the display panel and APP remote control but also five wind speed purification modes: peace of mind, comfortable space, keep fresh, circulation filtration and full purification. And in the peace of mind sleep mode, the sound is only 36 decibels, which is smaller than the sound of pouring water.

New air pollution killer PM0.3

Posted on by

New air pollution killer PM0.3

The smog weather in a field made consumers realize the harm of PM2.5. In fact, PM2.5 is only a van concept. PM2.5 in the consumer’s mouth, 95% of which is PM0.3, one is more than PM2. .5 small and nearly 600 times the “killer” can enter the lung particles!
Therefore, to be precise, PM2.5 can be subdivided into PM0.3 (below 0.3 microns) and narrowly defined PM2.5 (0.3 to 2.5 microns).
I believe that many consumers are familiar with PM2.5, but since China has not carried out PM0.3 monitoring on a large scale, many consumers still have a blank concept of PM0.3, which has led to many air purification products on the market. Remove the effect of PM0.3.
PM2.5, also known as fine particulate matter, refers to particulate matter with an aerodynamic equivalent diameter of 2.5 microns or less in ambient air. The higher the concentration in the air, the more serious the air pollution. How serious is its health and impact on human health? I believe many people have already experienced it personally. What is the focus on PM0.3?
What is PM0.3
PM0.3 is a general term for solid particles or droplets with a diameter of less than or equal to 0.3 microns. It is also known as a particulate matter that can be incorporated into the lungs. The particle size is smaller, only 1/200 of the hair. It is rich in toxic and harmful substances and has a long residence time in the atmosphere. PM0.3 can drift over 1000 km, which has a greater impact on human health and the quality of the atmospheric environment.
PM0.3 is not perforated?
Compared with PM2.5, which can only enter the lungs by breathing and block the alveoli, PM0.3 can be described as “pervasive” in the propagation channel. Because the particle size is only 1/200 of the hair silk, PM0.3 can not only reach the deepest part of the lungs through breathing, but also can swing into the alveoli and enter the blood tissue of the human body, and can not be removed permanently. Damage and prevention are far more difficult. We know PM2.5.
Due to the wide range of sources of PM0.3, people can hardly avoid contact with them in daily life. Studies have shown that more than 90% of PM0.3 comes from waste gas from power plants, factories and automobiles, and contains heavy metals such as mercury, cadmium, and lead. And stay longer in the air.
Indoors, PM0.3 mainly comes from decoration, home paints, and adhesives. After the PM0.3 in the air enters the human blood circulation, it will cause health hazards to many human organs such as cardiovascular and brain. Heavy metal PM0.3 will also damage the human respiratory system, immune system, and circulatory system. PM0.3 containing formaldehyde, benzene, and other substances is the root cause of leukemia, nasal cancer, and colon cancer.
PM0.3 is the most penetrating
For indoor air treatment, consumers generally accept air purifier products. The purification is mainly through increasing indoor air circulation and filter purification. The most efficient one is the HEPA filter, also called high-efficiency particles. There are four main filtering mechanisms for HEPA filters:
(1) The first type is the interception mechanism, and the removal of large particles is very obvious;
(2) The second mechanism is the influence of gravity. The particles with small volume and high density will reduce the movement speed when passing through the HEPA filter, and naturally settle on the HEPA filter;
(3) The third mechanism is the influence of airflow. Due to the uneven weaving of the HEPA filter, a large number of air vortices are formed, and the effects of the cyclone received by the cyclone are adsorbed on the HEPA to achieve the filtering purpose.
(4) The fourth filtering mechanism is that the ultrafine particles impinge on the HEPA filter fiber under the action of Brownian motion, and are filtered by electrostatic adsorption under the influence of van der Waals force.
Compared with smaller volume particles such as P0.1, PM0.3 is not easily affected by a cyclone or van der Waals force, and the capture mechanism of large particles also has little effect on PM0.3. Therefore, PM0.3 is also the most penetrating. The force particles measure the pros and cons of the HEPA filter, mainly depending on the purification efficiency of PM0.3.
to sum up:
For PM0.3 such fine particles, any mask is difficult to resist, the only way is to reduce pollution, and the purification products that are generally accepted by consumers in the market also take PM2.5 removal rate as one of the standards of cleanliness, but The study of PM0.3 can be said to be a blank.
The PM0.3 particles in the air can be removed from the air mainly through the HEPA filter. However, the industry has not yet made standards for the purification of PM0.3, which has also led to the uneven quality of HEPA filters. When consumers purchase air purifiers, In addition to avoiding the so-called “black technology” of the manufacturer, it is also necessary to pay attention to whether it is equipped with HEPA filter and the removal rate. Of course, the filter should be replaced and cleaned regularly to avoid secondary pollution.

Empty things? Do you really use air purifiers?

Empty things? Do you really use air purifiers?

If summer is the best air quality in a year, then the arrival of the autumn and winter season, especially for the small partners in the north, is not only the chilly wind but also the lingering weather… Because of this, the air purifier has become indispensable household equipment for many families. After reading the previous issue of “Essence of the Air | Just look at what you know, which air purifier should be selected”, perhaps We have learned how to choose an air purifier, but why do people often complain that the air purifier is not good or even clean? Is this a problem with air purifiers, or are we caught up in the use of air purifiers? Let us take a closer look at some of the problems that arise in using air purifiers today.

Don’t make common sense mistakes

Do you dare to remove the filter packaging?!

Generally speaking, the newly purchased air purifier should have the strongest purifying effect, but some people even complained to me that her new purchase of an empty net has no purifying effect. After reading the instructions several times, I have not found the problem. Already ready to return with the manufacturer.

Slow down slowly, are you really sure that it is empty? Sure enough, when I asked her if she had removed the packaging of the filter, she said that she was awkward and asked me if there was a package to be removed. I really cried out… Don’t think that this kind of thing will not happen to you. My friend is also smart and lively and cute, but in the end, it falls on the small thing of the filter.

There is no doubt that if the filter package is not removed, the air purifier will be the same as the “waste device”.

Finishing the wrong order

If the probability of not disassembling the filter package is not high, after all, many filters are installed directly in the air purifier without disassembling the package. Whether the filter needs to be installed in order, or how to put it all out, there should be a lot of doubts about this problem.

In response to this problem, we found a Sharp KI-BC608-W air purifier with multiple filters. From the schematic diagram of the official website, the correct installation sequence of the air purifier filter from the outside to the inside should be a rear panel (pre-filter), deodorization/formaldehyde removal integrated filter, formaldehyde removal filter, high-efficiency HEPA filter.

We disrupted the installation sequence by placing the deodorizing/deodorizing integrated filter in the innermost part, then placing the formaldehyde removal filter and the high-efficiency HEPA filter. A cigarette is lit in a house with a closed door and a window of about 10 square meters. It is measured by an air quality measuring instrument. We can see that the air quality in the initial environment is as follows: the formaldehyde value is 0.11 mg/m3, PM2.5. The value was 556 μg/m 3 and the pollution index was 500.

When we started the air purifier that disrupted the installation sequence, after 10 minutes of use, the air quality was 0.001 mg/m3, the PM2.5 was 257 μg/m3, and the pollution index was 307. The pollution situation has eased, but it is clearly still in a state of explosion.

Therefore, we adjusted the filter to the normal installation sequence. After ten minutes of opening, the value was 0.11 mg/m3, the PM2.5 value was 38 μg/m3, and the pollution index was 91. Although the formaldehyde value did not decrease, both PM2.5 and the overall pollution index showed a significant downward trend. It can be seen that the correct installation order of the filter does affect the purification effect of the air purifier. To say the loss, the incorrect installation sequence must be greater than the correct safety loss, and the effect is still poor.

So, if you bought an air purifier that needs to install multiple filters, you really have to look carefully at the filter installation sequence.

Do you have to do this with an empty net?

Empty net + humidifier ≠ double insurance

Sometimes we feel that an air purifier can’t solve the problem of indoor air quality (then buy two), so we will look for ways that seem to be able to “snap” with the air purifier. For example, if someone puts a humidifier next to the air purifier, can this really do more with less? Still, let the data speak.

This time we chose the Dustie DAC500Plus air purifier, which still ignited a cigarette. In the closed window environment of the same 10 square meters, the measured index is: formaldehyde value is 0.09mg/m3, PM2.5 value is 235μg. /m3, the pollution index is 285. Ten minutes later, the index was: formaldehyde value of 0.05 mg/m3, PM2.5 value of 16 μg/m3, and pollution index of 41. It was obvious that the indoor air environment quickly returned to the ideal state by itself.

If you have a humidifier next to it? So we put another cigarette, the measured index is formaldehyde value of 0.10mg / m3, PM2.5 value of 197μg / m3, pollution index of 247. After turning on the air purifier and humidifier, wait for 10 minutes. The measured index is: formaldehyde value is 0.05mg/m3, PM2.5 value is 42μg/m3, pollution index is 58, the data performance is also good, but if you If the room is not particularly dry, just to purify the air purely, there is no need to open a humidifier at the same time.

Open the net and open the window?

Undoubtedly, if the quality of the outdoor air is very bad now, then you open the air purifier and open the window is undoubtedly a chronic suicide. But if the outdoor air quality is good, and I also need certain window ventilation, will the indoor air be better when the purifier is turned on? Let’s try it out.

The Dustie DAC500Plus air purifier was used. The air quality on the day of the test was good, the blue sky and white clouds, and the weather forecast did not show any pollution problems such as foggy weather. This time we did not deliberately smoke, because we should test in a normal indoor environment, open the air, the measured data after ten minutes is formaldehyde value of 0.10mg / m3, PM2.5 value of 9μg / m3, pollution index It is 83.

Subsequently, the indoor window was directly opened and waited for 10 minutes. The data showed a formaldehyde value of 0.07 mg/m3, a PM2.5 value of 2 μg/m3, and a pollution index of 58. It can be seen that after opening the window, the values ​​of formaldehyde and PM2.5 have decreased, but the overall pollution index has not changed. This shows that air circulation still has certain benefits, but the premise is that the weather must be good. The weather is not good, anyone knows that opening the window is dead.

Put the same air purifier

It is said that the air quality in the central part of the air purifier is the best, and the empty net placed on the side of the wall or on the side of the furniture is compared with the empty net placed without any obstructions around it. At the same time, the purification effect will be Not the same? We still try the Dustie DAC500Plus air purifier.

When we placed the purifier on the wall and turned on the purifier for 10 minutes, the test data showed a formaldehyde value of 0.08 mg/m3, a PM2.5 value of 30 μg/m3, and a pollution index of 66.

After that, the air purifier was removed from the wall and placed in a place where there was no obvious obstruction around it. It was opened for ten minutes. The test data showed a formaldehyde value of 0.08 mg/m3 and a PM2.5 value of 19 μg/m3. The index is 66. Obviously, except for the decrease in the PM2.5 value, the other values ​​have not changed. It can be seen that it is placed on the edge of the wall and does not have much influence on the purification effect of the air purifier.
