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.

Home and office health artifacts: functional water machine, air purifier

People want health is systematic engineering, in which “environment” and “habit” are the big source of disease. The air we breathe and the water we drink are the most important factors. They are both environmental factors and habitual factors (environment and habits, and other aspects such as soil, emotions, etc.). From the air and drinking water, we start from the source. It is inevitable to work hard without changing from the source because the temporary treatment of health care is not able to compete with the environment and habits.
Modern research on the harm of air pollution and water pollution to health does not need much to say here. It is only mentioned that water pollution may mainly lead to diseases such as stones, cancer, heavy metal poisoning, cardiovascular and cerebrovascular diseases, digestive diseases, etc. Air pollution is easy. Lead to lung cancer, leukemia, chronic obstructive pulmonary disease, asthma, rhinitis, skin diseases, and other diseases. It is emphasized here that Chinese medicine is also unparalleled in its emphasis on air and water. Research on air and water is rich in content. For example, air, the corresponding nouns in ancient Chinese medicine are the heavens, the weather, the essence, the anger, the Tianyang and so on. “The Yellow Emperor’s Internal Classic” discusses what is “real person”, “there are people in the ancient times, who raise the world, grasp the yin and yang, breathe the essence, keep the gods alone, and if the muscles are one, they can hide the heavens and the earth, and there is no end to it.” If the air is polluted, how can it be “breathing” and how can it be made into “real people”? He also said that “the weather, the clean and bright people, the Tibetans are not limited, so they don’t go down,” “the heavens are qi, the clean is the ambition,” Imagine if the air is polluted, it is not called clean, and you can “Joshi” (Mental state is very good)? Conversely, air pollution is one of the causes of upset and even mental illness. In the Qing Dynasty, Tang Rongchuan said, “The air of the human body is born in the umbilical dantian, the sea of ​​air, the umbilical lower, the kidney and the bladder, and the place where the water is homed. This water is not self-contained, and it is absorbed by the nose. Yang, from the lung tube to the heart fire, under the umbilical, steaming its water to become gas”, it seems that breathing good air has a vital role in normal physiological activities. So there is no good airline? ! In terms of water, for example, Zhang Zi and Zuo Zhi in the Confucianism of the Confucianism are an important article in the theory of Chinese medicine.
The use of advanced water purifiers and air purifiers can directly improve the body. Hangzhou New Youth Hertz Super Energy Instrument (functional water machine) I have used it for more than 3 months, and all aspects have been improved obviously. Many people have witnessed it. Another example is the Shan Yimei brand air purifier. I have personally experienced the blood test comparison experiment, that is, before and after using the air purifier (in the room where the air purifier works) (30 minutes – 60 minutes indefinite), use ” A drop of blood instrumentation can see the quality of the blood (such as the number of red blood cells in the same field of view, blood viscosity, blood cell viability) has been significantly improved. And it is true that in such a room, the mind is fresh, responsive, and unconscious. The changes in blood status are shown in the figure.
This makes the author very shocked, because we do health care, regardless of technology, or products, and ultimately we must improve the quality of blood, and this air purifier is easy to do, and we work hard to do physical therapy, not necessarily It is possible to achieve such an obvious effect, which can be said to regulate the body and improve health only between breathing. This also caused the author to reflect, our treatment and conditioning methods can not fall too far into the box, the role of the best air purifiers is also a way to treat conditioning, and deep medical treatment; Western medicine ventilator, all kinds of qigong, breathing exercises Law, drug fumigation, are worth pondering. As far as water is concerned, “spa” is also completely identifiable and very valuable.

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”.

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

Posted on by

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.

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.

Five factors that determine the purification effect of air purifiers

Posted on by

Five factors that determine the purification effect of air purifiers

For air purifiers, the purification of air is the primary condition for measuring the quality of an air purifier. In addition, it is energy consumption, noise, service life, and other considerations. Then, from the technical materials and conditions of the use of air purifiers, what are the main factors affecting the purification effect of air purifiers?
The first is the filter material of the air purifier. For air purifiers, the purification effect is mainly from the filter material. Generally speaking, air purification filter materials have various limitations, such as non-woven fabrics, filter papers, etc., to ensure good ventilation, but also to effectively filter harmful substances in the air, the two are difficult to balance. Although activated carbon has a strong adsorption capacity, it is easy to saturate. With the results of the pollutants, the purification effect will be significantly reduced. In different indoor environments, the requirements for air purifier filters are different. Therefore, in the process of selecting an air purifier, whether the function of the filter material meets the actual needs, whether it is convenient to replace, the service life, etc., is the first problem to be considered.
Followed by the performance of the air purifier fan. The purification efficiency of the air purifier is closely related to the size of the air volume. Because the purification process of any air purifier requires air to pass through the purification device inside the purifier, and the fan is the energy source of the air circulation. In general, the higher the power of the fan, the higher the purification efficiency and the greater the noise. However, the silence of the air purifier structure is the mainstream method for most powerful air purifier brands to reduce the noise of high-power fans without affecting the purification efficiency.
Again, the object to be purified by the air purifier. In general, air purifiers on the market are targeted. For example, some air purifiers mainly purify and adsorb chemical pollutants, and the effect of purifying formaldehyde pollution on new decoration and new furniture is obvious; some are mainly aimed at efficiently filtering inhalable particles in the air. Of course, there are also air purifiers that are ingenious to kill bacteria, germs, and maintain human health and safety, such as Aegis. When consumers choose an air purifier, they should consider the air pollution of the applied place more and choose the air purifier.
There is also an air purifier workspace volume that is also a part that needs attention. Different air purifiers have different effective workspace volumes due to different fan and performance designs. For example, an air purifier with an air volume of fewer than 120 m3 per hour is used in a room below 20 m2, and the purification effect is most obvious.
Finally, it is necessary to clean the level of pollution in the room. The degree of indoor air pollution is also one of the factors affecting the purification effect of air purifiers. For example, in the environment with a high concentration of chemical pollutants, it is necessary to replace the adsorbent materials more frequently. In the summer when viruses and germs are more likely to breed, it is necessary to pay attention to antibacterial peptide filtration. The sterilization effect of the net.
In general, the filter material and the adsorbent material are determined for the service life and purification effect of the air purifier; the design of the fan and the air duct is determined by determining the energy efficiency of the air purifier; the overall structure safety and noise effect of the air purifier is determined by the outer casing of the air conditioner. And electromechanical; it is the monitoring system and display system that determines the ease and intelligence of the air purifier. Depending on the specific needs of air purification, air purifiers also have a variety of changes in detail, which also gives consumers more and more accurate air purifier products to choose from.

Household air purifier can effectively improve summer “air conditioning disease”

Posted on by

Household air purifier can effectively improve summer “air conditioning disease”

The summer weather is hot, and it is almost necessary to close the window to turn on the air conditioner to cool down. We know that the elderly, pregnant women and infants are relatively weak people. However, indoors are not ventilated for a long time, and the air quality is poor, but people are worried. Whether it is indoors or outdoors, healthy breathing is particularly important.

According to a report on the Internet, according to the research report, the carbon nanoparticles in PM2.5 have obvious damage to the first pregnancy. The smog contains a large number of particulate pollutants such as PM2.5, which can induce various respiratory tracts. Diseases, especially mothers and babies and the elderly, are more vulnerable. Many pregnant women, the elderly, and children breathe fresh air, sunbathe, go out for a walk, and do sports. But sometimes there will be smog days, the outdoor air pollution is serious, but in desperation, I have to go home to “hide” and dare not go out.

The reduction of outdoor sports means an increase in indoor activities. The weather with severe outdoor air pollution leads to a reduction in the number of window ventilation. The exhaust gas generated by indoor activities, the harmful gases emitted by furniture, and the smell of cooking smoke can not be discharged in time. The air does not input in time, the indoor air is not circulating, and the indoor air quality is actually worse. Indoors with severe air pollution are prone to dizziness, vomiting and other symptoms, and may even cause respiratory diseases.

Experiments have shown that for every 1 °C rise in room temperature, formaldehyde volatilized from wooden furniture and flooring will increase the concentration of formaldehyde in the air by 0.15 to 0.37 times. In the high temperature and humidity environment both indoors and outdoors in summer, it will accelerate the release of formaldehyde in furniture and other decoration materials. To this end, experts have called for the rational use of air purifiers with formaldehyde-removing functions during the summer to improve and improve air quality and reduce indoor air pollution.

An indoor household air purifiers can not only remove smog particles such as PM2.5 but also dust and odor, etc.; it can also decompose harmful gases such as formaldehyde and benzene. It is a good choice to provide a healthy breathing environment for your family and to care for your family’s health. Especially in the summer season, the weather is hot, the air conditioner is turned on, the ventilation is less, the air is not circulated, and the exhaust gas in the home cannot be discharged in time. It is especially important to provide a good breathing environment for your family at this time. So how do you choose an indoor air purifier?

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.

How to convince the boss to buy an air purifier?

How to convince the boss to buy an air purifier?

The office space is large, the number of people and the miscellaneous items are extremely complicated indoor environments. The decoration materials are just one of the many sources of pollution. Moreover, environmentally friendly materials only control the volatile concentration of pollutants below the national standard, and it does not mean that it does not exist.
Sources of pollution: The source of indoor pollution is very complicated. First, the decoration materials are polluted. Tables, chairs, wallpapers, and floors may emit formaldehyde. The carpet may release formaldehyde and dichlorobenzene. The paint on the surface of the file cabinet is benzene, toluene, and xylene. The main source; the second is the pollution caused by office supplies and the surrounding environment, such as the electrostatic effect of the printer under working conditions, will produce a lot of ozone and dust, even the cleaning agent will release a variety of volatile organic compounds and ammonia during use. Irritating gas.
Gathering more and more: Even qualified materials mean that the content of toxic and hazardous substances is below a certain standard, not without. Therefore, if a large amount of the same material is used in a room, the indoor air quality may not meet the requirements or even exceed the standard due to the additive effect.
Statistics: The China Indoor Decoration Association Environmental Testing Center has conducted sampling tests on indoor air in Beijing’s office space. The results show that the excess rates of harmful substances such as ammonia and formaldehyde are 80.56% and 42.11%, respectively. Overall, the air condition of the office space is still not optimistic.

Rumor
▼
Central air conditioning and fresh air systems are not only unable to fundamentally solve the problem of air pollution. If they are not cleaned up, they are more likely to become new sources of pollution.
Microbial base camp: If the central air conditioner is operated for a long time and has not been cleaned for many years, the dust in the air duct can be as thick as three or four centimeters. It can easily become a medium for viruses, bacteria, fungi and other microorganisms under constant temperature and humidity conditions. Air circulation spreads throughout the space, and diseases transmitted through the respiratory tract are more easily spread.
Secondary pollution: The main function of the fresh air system is ventilation and ventilation. In the process, although the introduced fresh air is also filtered, the filtering effect is not ideal when the outdoor environment is very bad. In particular, although some office buildings have a central fresh air system, they may not be opened for a long time, or they may not be maintained for a long time, and the latter may easily cause secondary pollution of dust.
Cruel reality: The National Health Department’s spot check report of 937 central air conditioners in Beishangguang and some provincial capital cities shows that 47.1% are serious pollution, 46.7% are moderately polluted, and the pass rate is only 6.2%. The detection indicators are dust accumulation, bacterial content and fungal content. It can be seen that central air-conditioning has gradually become a source of pollution that cannot be ignored in office space.

Rumor
▼
People often associate green plants with air-cleaning guardians. However, it is also overestimated to get air pollution by relying on a few leaves.
If you really want to rely on plants: Take formaldehyde as an example. According to the research data of China Agricultural University: in a room with 100m2, 3m height and 0.2mg/m3 formaldehyde concentration, 1800 pots of green radish are needed at the same time. Reduced to the national standard of 0.08 mg / m3, this is still in the case of sufficient daylight, and to ensure that no formaldehyde is released during the absorption process – and in fact, the formaldehyde in the room after renovation is constantly being released. Therefore, it is not practical to rely on plants to remove formaldehyde.
Overestimated green plants: As for particulate pollutants, it is even more impossible to expect green plants. Plants only exchange gas with the environment through the pores of the surface, but they do not actively adsorb particles. The dust particles in the air can only be passively deposited on the surface of the plant, and finally only the ending of a layer of gray on the leaves.

“China Air Purifier Industry White Paper (2019)” released

The “White Paper on China’s Air Purifier Industry (2019)” released in Beijing recently pointed out that in addition to formaldehyde, it is becoming a breakthrough point in the transformation and upgrading of the air-net industry. The report compiled by the big data company Aowei Cloud Network (AVC) and other institutions show that in 2018, China’s air purifier market was 11.67 billion yuan, down 28% year-on-year. The sales penetration rate of high-efficiency formaldehyde removal products (formaldehyde CADR ≥ 200) reached 18.5%.
Reduced smog
1
On May 24th, sponsored by China Household Electrical Appliances Association, Shanghai Environmental Protection Industry Association, Shanghai Environmental Protection Industry Association Air Clean Equipment Committee, Air Purifier (China) Industry Alliance, Beijing Aowei Cloud Network Big Data Technology The “2019 China Air Purifier Industry Summit and China Air Purifier Industry White Paper Conference” hosted by the company was held in Beijing, and the “China Air Purifier Industry White Paper (2019)” was released, aiming to guide the industry to a stable Sustainable development.
The summit focused on the theme of “winning the aldehydes and winning the market and enjoying the rebirth of innovation”, and conducted in-depth exploration and discussion on the performance of the past air purifier market, future technology, and market development trends. Experts at the conference said that the air purifier market is currently at low tide, and the overall industry is suffering from a sharp drop in consumer demand. Enterprises are also actively looking for new demand points, such as formaldehyde-free air purifiers, which are products that consumers really need. It is a product that can adapt to the needs of the market and bring about industry growth. In the future, industry organizations will assist production companies in the development of relevant standards and events, and promote the transformation and development of enterprises. The summit issued a heavyweight “China Air Purifier Industry White Paper (2019)” to guide the industry to stable and sustainable development.
The bad weather conditions of the past few years have made the empty net industry of “depending on the sky” expand rapidly. Since 2018, China’s environmental governance has continued to deepen, weather conditions have improved significantly, consumers’ panic buying behavior has ended, and it has begun to enter the era of rational purchase.
The haze is reduced, and the aldehyde is new. Faced with changes in the situation and demand, air purifiers are actively looking for new demand points. The problem of interior decoration in China has been prominent, and the rate of formaldehyde exceeding the standard is high. Coupled with the impact of unexpected events, consumers “except aldehyde” Consciousness is further awakened. The formaldehyde release cycle is long. Except that formaldehyde is systematic and long-term work, the formaldehyde air purifier is just in line with this characteristic, and it can be used for a long time. As a result, the future of the air purifier is still limitless.
Functional improvement
2
From January to April 2019, the market size of the air purifier was 2.94 billion yuan, down 21.5% year-on-year, and the market’s downward trend was obvious. In terms of products, in addition to formaldehyde purification and penetration rate continues to rise, but the product price is higher, the technology is mainly adsorption, there is still a large room for development in the future.
At present, the development status of air purifier products: After the introduction of formaldehyde-removing products, enterprises are constantly looking for new consumption pain points and launching more products that meet market needs.
In order to further explore the industry situation, experts at the meeting exchanged views on the status quo and development expectations of the industry. They agreed that although the formaldehyde function is not a new function, the technology has been updated to meet the needs of consumers. With the advancement of technology, the function of formaldehyde removal will be further improved and the effect will be continuously improved.
For the development of air purifiers, experts who participated in the discussion believe that people’s pursuit of healthy quality life has no end, which means that consumers’ demand for air purifier products will continue to increase, and the market prospects are still worth looking forward to.
The newly released “White Paper on China’s Air Purifier Industry (2019)” shows that at present, the air purifier industry is at the stage of bottom-side adjustment. The “White Paper” concluded that after the explosive growth, the brands and products of air purifiers on the market were uneven. After rapid development, there were problems such as single product function, uneven brand, weak after-sales service, and poor product stability. In the future, industry standards will be more standardized, product functions will be more diversified, policy subsidies will be in place, consumer awareness will increase, and the potential of the air purifier industry should not be underestimated.
Lu Jianguo, the deputy chief engineer of the China Household Electrical Appliances Research Institute and director of the Institute of Test and Measurement Technology, explained in detail the standards and industry standards for air purifiers at the summit. Lu Jianguo said that standards can not only regulate the manufacturing behavior and benign competition of enterprises but also play a role in guiding consumers to purchase.
Industry observers pointed out that the decline of the air purifier industry after the outbreak of growth is a pain in development and will not affect the overall industry to move forward steadily. With the development of the social economy and the awareness of residents’ healthy living, the future development of the air purifier industry is huge, and the industry will eventually move toward a benign development path.
