The water purifier is a display? After reading you, you are silent!
The importance of water to human health, I am afraid everyone can say one or two. However, our daily tap water has experienced too many cruel flaws in the processing, rust, heavy metals, pesticides, dyes… and various viruses, bacteria, and other microorganisms, even after boiling, simple sterilization Chloride and heavy metals in the water will not decrease. Therefore, it is very important to filter the water and drink it.
However, the filter kettle is slow to filter, the RO water purifier is bulky, the installation is troublesome, the price is high, the faucet water purifier is more friendly, the purification is quick, the price is close to the people, the volume is still small… except that the purification effect is not known, everything looks They are perfect. In order to answer the doubts and confusion in everyone’s mind, today we will test and monitor the faucet water purifier.
The packaging looks very textured. The water purifier looks like a camera lens. At first glance, it is super technical, and the middle LED lights are very cool.
The fittings for all kinds of faucets are all in line, 3 internal thread adapters and 1 external thread adapter, which can match the various thread taps that are common in the market. There is also a separate monitor cover that can be attached to the adapter when the filter is removed.
Remove the bubbler of the faucet and gently rotate it up. It is more labor-saving than installing the bulb, it does not occupy the place, it is light and easy to carry, and it can be brought together on a business trip.
After opening the one-eye intelligent monitoring faucet water purifier, then turn on the Bluetooth of the mobile phone, the “One Eye” APP will automatically search and match.
Of course, it is definitely not only because it is convenient, after all, but there are also many products of the same type on the market. I value its water purification technology and its own monitoring module. The two functions are two of its biggest highlights. It is said that after the filtration, the detection module of the palm of the hand can accurately detect various data in the water, and score the water quality so that you have a number before you drink.
Its filter element is also full of black technology. The activated carbon fiber + ion exchange fiber selected for the one-screen composite filter has a large micropore content, a narrow pore size distribution, and a surface area twice that of the ordinary filter element, which means that the filtration capacity is stronger and the purification effect is obtained. How to know it.
Turn on the faucet and in the original water state, the TOC, TDS, turbidity and temperature data in the water are detected in a few seconds, and the four-color LED lamp is used to indicate the quality of the water. Turn the switch to the side and turn on the clean water. The tap water comes out of the faucet and is filtered through a multi-brand composite filter. Then it is clean and healthy water. The LED light turns green instantly. This purification effect is obvious~
Raw water, clean water status LED light display
Moreover, these detailed water quality data are uploaded to the mobile app, and the water quality is intelligently scored by the AI big data algorithm. You can see the filtering effect and the quality of the water at a glance based on the monitoring results.
What is the effect of using an air purifier to remove formaldehyde?
Many families choose to use an air purifier to remove indoor formaldehyde after renovation, but can the air purifier really remove formaldehyde? What about the effect?
First of all, we can be sure that some air purifiers do have the effect of removing formaldehyde, but we must also be clear that the effect of using air purifiers in addition to formaldehyde is not as good as the promotion of the business.
Air purifiers refer to home appliances that can adsorb, decompose or convert various air pollutants and improve air cleanliness.
There are two main methods for removing formaldehyde from air purifiers on the market. One is to filter formaldehyde to remove formaldehyde. The principle is the same as that of activated carbon except for formaldehyde, and this filter needs to be replaced frequently. The other is a negative ion air purifier. The negative ion bioactivity generated by it neutralizes harmful substances in the air.
Song Guangsheng, director of the China National Indoor Interior-Environment and Environmental Product Quality Supervision and Inspection Center, said in an interview with the media that most of the air purifiers on the market claimed nearly zero formaldehyde removal. First of all, the presence of formaldehyde is not a one-time, but slowly accumulated through the long-term decoration process, formaldehyde from a variety of carriers is more and more continuous, it is difficult to quickly and effectively remove, which requires a long-term process To volatilize. In addition, the CADR value of the purified air pollutants will be at least 60m3/h, which will be effective. Due to the continuous release of household formaldehyde, the actual effect may not reach 29m3/h.

The classroom should be equipped with an air purifier with disinfection and sterilization functions.
Not only did the parents choose to send their children to school in the fog, so the air quality in the classroom became the focal point of the family. Not only do the parents want to add air purifiers to the school.
But how do you choose an air purifier suitable for classroom installation?
/ Zhang Jian, chief physician of Pediatrics, Beijing Chinese Medicine Hospital:
At present, the air purifier is mainly for household use, and the home environment variable is small and relatively effective.
However, in school, especially in the classroom, it is a public space. The school classrooms are mostly 65 square meters of standardized buildings, and the factors affecting the environment are more complicated.
“Recently, some children have a fever and a dry cough, which is also related to viral infection.”
Therefore, an air purifier with disinfection and sterilization functions should be installed in the classroom.
/ Vice President of China Academy of Environmental Sciences Chai Fahe believes that:
Air purifiers need to be closed for doors and windows. There are many people in the classroom, but the environment is too closed for the body.
If you say that while purifying the air, it also has a bactericidal function, which invisibly creates an invisible protective wall for the classroom to isolate the bacteria and protect the health of the students.
If you want to add, you should choose an air purification device that can remove PM2.5 and sterilize.
/ A small school principal in Haidian District, Beijing said:
The air purifier should be used in a relatively closed environment. The carbon dioxide exhaled by dozens of students will make the air in the classroom very turbid. It will be boring in the classroom for a long time, which is not conducive to the health of the students, but also easy to cause flu, hand, foot, and mouth. Epidemic diseases such as diseases.
It is necessary for schools to purchase air purifiers with air disinfection.
/ Parent representative:
There are many students in the school classroom, the seats are very close, and the children’s resistance is insufficient. It is inevitable to be infected with some epidemic diseases. It is very hard for children to go to school. If the smog weather is still in class, it is a test for the child’s body.
I hope that the school can install air purification equipment with air disinfection function to ensure that children are not harmed by bacteria, viruses and air pollution in school.
Most car air purifiers are limited by power and other factors. The function of “eliminating” PM2.5 is limited, and the effect is not as good as the internal circulation system of car air conditioners.
In the survey, most people in the industry believe that most of the car air purifiers on the market currently have the function of “eliminating” PM2.5, and most of the purifiers use the filter to absorb harmful substances in the air, which is easy to accumulate. Cause secondary pollution.
In many shopping websites, car air purifiers and anti-smashing masks have become hot items in winter. In a website, the reporter searched for car air purifiers, and there were more than 10,000 pieces of product information, including formaldehyde, odor, and PM2.5, which became the key selling points of some merchants’ recommended products.
According to the brand and function, the price of car air purifiers ranges from tens of yuan to several thousand yuan. Among them, a recently-selling car air purifier claims to use high-tech nano-purification in its advertisements. Its high-efficiency air filtration system can not only effectively remove PM2.5, but even filter 99.9% of particles as small as 0.3 microns. Other products claim to purify the interior air by electrostatic precipitator sterilization, activated carbon filters, or low-temperature non-plasma.
There is also a store introduction, the car air purifier sold by the active release of a large number of positive and negative ions, capture and eliminate the bacteria in the air, so as to achieve the purpose of cleaning the air inside the car. It is said that negative ions have the effects of oxygenation and freshening, sterilization and disinfection, sedimentation of dust, neutralization of radiation, and refreshment.
Is the car air purifier so amazing?
Not long ago, someone in Beijing especially did a simple test to verify the purification effect of a car air purifier with a price of 796 yuan.
The purifier is marked with an area of 10 square meters and the PM2.5 concentration measured in the car before opening the purifier is 458 μg/m3. When the purifier was turned on, it was found that the speed of air quality change was not ideal. After 25 minutes, the PM2.5 value reached 14 μg/m3, and the PM2.5 tester showed that the air quality was “excellent”.
Afterward, the tester opened the window, restored the air quality inside the car to the initial condition, closed the window and opened the vehicle’s internal circulation system. At this point, the value on the PM2.5 tester dropped rapidly, and the concentration dropped to 14 μg/m3 in just 5 minutes.
A hospital respiratory expert interviewed by the reporter said that most of the car air purifiers on the market are far less powerful than the internal circulation system of the vehicle, and it is difficult to achieve indoor air purification in a short time. If the adsorption device of the car air purifier is saturated, the cleaning effect will be greatly reduced, and secondary pollution is likely to occur, which will cause harm to human health. Therefore, a car purifier is not a “tool”.
The store specializing in the sale of car accessories told reporters that the key to the effectiveness of air purification equipment lies in the filter screen, and the car just provides us with such a filter screen – the car air conditioning filter is a standard HEPA filter, which means only need to turn on the air conditioner. Ventilation can effectively purify PM2.5.
However, he also warned that there are still some vehicles that do not have such an efficient filtration system installed.
It is understood that although the purifier negative ion purification technology promoted by merchants can make dust particles settle and kill bacteria, experts say that its comprehensive purification effect is poor, because it can not remove organic substances such as formaldehyde, and settled particles and bacterial residues remain. In the car, it is easy to produce a “black wall effect.”
The indoor and outdoor PM2.5 concentrations are not much different. Even if the window is closed, the indoors are only 100 times slower than the outdoor. According to the current explosion weather, the outdoor air is also about 450. Toxic” level. Moreover, in the room where the window is closed, the human body acts as the main purification device. This is also the main reason why the indoor PM2.5 index can slowly decrease after closing the window. Because they are all sucked into the body by you indoors! The reliable air purifier can greatly reduce the indoor PM2.5 concentration and maintain it in a short time so that the indoor air is in a safe range for a long time.
The original function of the air purifier is so powerful!
Many people think that the best quiet air purifier is not useful, because the air can neither be seen nor touched, and the purification effect of the air purifier is difficult to be directly felt by us. In fact, the role of the air purifier is still very large, can help us to remove some of the fine particles and harmful gases that are harmful to the body.
First of all, indoor pollution can be roughly divided into two categories: excessive particulate matter and volatile organic compounds exceeding the standard.
Among them, there are many kinds of particulate matter, such as dust particles brought in from outside, as well as PM 2.5, allergenic pollen, bacteria, viruses, swarf keratin, pets and so on. If the particles are inhaled too much and deposited in the body, it may cause respiratory diseases and even increase the risk of lung cancer and heart disease. Bacteria and viruses can cause skin irritation and illness.
Volatile organics, also known as VOCs, are mainly derived from combustion products such as coal and natural gas, smoking, construction and decorative materials, furniture, household appliances, detergents, and the body’s own emissions, as well as paints used in decoration. , coatings and adhesives.
The hazard of VOC is obvious. When the concentration of VOC in the room exceeds the standard, people will feel nausea and headache. If it is serious, it will be comatose because it will damage the liver, kidney, brain and nervous system of human beings.
The S40 is equipped with the Olansi full-speed ultra-fast filter system for 400m3/h particulate CADR and P4 CCM for heavy indoor pollution. At the same time, in order to solve the formaldehyde super phenomenon that often occurs in modern homes, S40 also provides up to 300m3 / h formaldehyde CADR and F4 grade CCM, long-term removal of formaldehyde.
The measured data shows that the formaldehyde purification rate is 99%, and the TVOC purification rate is more than 98%. Excellent performance with this sleek and generous design also makes it better integrated into the home environment, is a purifier and also an ornament.
Olansi is a healthy home appliance brand that focuses on the smart home ecology. It is committed to creating a beautiful life for people with technology and human care with the concept of “human text”. It integrates design, research, and development, production, sales and service into one. The young design concept and the people-oriented brand values provide users with fashionable and reliable health appliances such as air purifiers and water purifiers.
With the promulgation of the new national standard, consumers can further understand the meaning of the various indicators of the new national standard, and select the most suitable products according to the actual needs of individuals, measuring the purification area, filter life, and other comprehensive factors. For brand manufacturers, not only need to deepen the needs of users, and constantly improve the product functions but also need to make the new national standard related specifications more concise and complete, easy to understand, which helps consumers to actively choose the right products.

Air purifiers “life and death”: Internet companies push hard to launch black horses
To be precise, the best era of air purifiers appeared in 2014, when the empty net products were full of mystery in the eyes of consumers, and Internet vendors brought a lot of focus to a single story.
After three years, the prosperity of the empty net market seems to be re-enacted. The little-known 352 environmental protection technology has won the largest financing in the air net industry so far. The painful transformation of Jumei has extended one foot to the air purifier, and the ink weather, hammer and so on have also seen the dividend of the empty net market… …
But on the other side of the coin, the Olansi air purifier was taken to the altar, but it fell into the “quality gate” several times; Fu Sheng, who claimed to be “a patient with dust allergic rhinitis”, was close to his “leopard meter”. People’s vision disappeared. Now that Internet companies are once again building up a net market, are they ready to face a “life and death”?
Barbaric growth under the bonus
Even after three years, the dividend in the net market does not seem to be exhausted. In 2016, the market size of domestic net products reached 5.74 million units, and the retail volume and retail sales achieved year-on-year growth of 19.3% and 23.6% respectively. Some people have calculated an economic account. The market penetration rate of empty-net products in the United States and Japan has reached 27% and 17%, and South Korea is as high as 70%. In contrast, the domestic market is only about 1%. The potential market space is not mentioned. And Yu.
In addition, according to the estimation of China Industrial Research Institute, the sales volume of air purifiers in China will continue to grow at a rate of 30%-35% in the future. It is expected that the sales volume will reach 100 billion yuan in 2017 and 300 billion yuan in 2020. A new market of 100 billion.
The rise of the empty net market is inseparable from two major incentives. One is that under the influence of a series of marketing renderings, the idea that air purifiers become “necessities for life” has gradually gained popularity, especially the promotion of consumption upgrades and the growth of the new housing market in recent years. Directly promoted the market demand for empty-net products;
The other is the rapid maturity of the empty net upstream and downstream industries. Up to now, there have been more than 700 air purifier brands in China, including overseas imported products, also transformed home appliance manufacturers, and entrepreneurs and Internet companies across the border.
However, most of the empty net brands rely on products, not products or technology, but capture the consumer’s “psychological appeal” marketing strategy. From the end of 2012, PM2.5 began to become seasonal news. Focus, every autumn and winter season, the media will expose PM2.5 related burst numbers, arousing consumers’ fear and empathy.
Perhaps at this time, there are already many net brand nets stealing music. “Fear” is a very magical phenomenon. Even if you know that buying an air purifier may not solve the air quality problem, at least there is psychological comfort.
From the perspective of an empty net manufacturer, this is the so-called dividend, which is especially true for Internet companies. The pricing of foreign brands such as Philips and Aegis is generally more than 3,000 yuan. The price of 352 series air purifiers sold in Jingdong, Tmall, and other e-commerce platforms is more than 1,000 to 2,000 yuan.
Internet vendors have keenly realized that this price will undoubtedly entangle some consumers, and they want to occupy the “secondary consumption power” market that these brands cannot cover, so whether it is Olansi Or Leopard, the price is below 1,000 yuan.
However, a good set of imported air purifier filter cores cost nearly 1,000 yuan. The performance of the machine below 1,000 yuan and the quality of professional air purifier brands are still quite different. Therefore, because some of the consumption stocks in the market do not have the ability to identify, the figure cheaply buys a “psychological comforting” air purifier, and this part of the consumption stock will eventually be selected again with the poor experience of use, returning to the market and becoming empty. Net new consumption power.
The mysterious empty net market
In March of last year, the National Standards Committee approved the issuance of the newly revised “Air Purifier” national standard, the CADR value (the higher the value, the higher the efficiency, the larger the applicable area), and the CCM value (the larger the value, the longer the filter life. The better the quality of the filter, the energy efficiency rating and other indicators are clearly defined.
However, the higher industry threshold still fails to stop the entry of Internet companies that are “all-powerful”. Jumeiyou, Ink Weather and Hammer Technology released news of air purifiers
At the APE air product launch conference, Reemake Air One and Reemake air one plus have CADRs of 1000 and 2000 respectively. Compared with the CADR value of Olansi Air Purifier 406, several times of advantageous crushing has been formed. Coincidentally, the CADR value of the ink air purifier reached 450. In order to match the price of 2,999 yuan, I have always compared myself with international big brands in marketing and publicity. What is curious is that the first air purifier of the hammer, how will Lao Luo sell his feelings?
Still, the hardware product is not a simple data overlay. After all, it is not a matter of software knocking a few codes than data, but a comprehensive performance. Internet brands cross-border, often fall into the marketing thinking of “word games” and “digital games.”
For example, the Olansi air purifier has been questioned a lot. The so-called 406CADR can only be achieved in high-speed mode, but the noise has reached 75 decibels, which is close to the limit of human ear comfort. Under normal conditions of 40 decibels, The CADR value is only around 200-300, which does not provide basic suction power. Olansi is still like this, and the empty net products of other Internet brands can be imagined.
In contrast, the performance of professional brands in the industry is more pragmatic. Take the second product X83 air purifier released by 352 Environmental Technology as an example. The CARD value of the particulate matter reaches 750m3/h, and the applicable area of the machine is 52-90 square meters. The sound power level noise is only 64.4dB, and the lowest sound power level noise is 34.5dB, which is close to the decibel number of the leaves (30dB).
The savvy capital circle sees the true face of the empty net market before consumers who are still in the ignorant period. 352 environmental protection has been a positive signal from the investment of 200 million yuan such as Bertelsmann, Jingwei Venture Capital and Huatai Fund. The capital is concerned not only with the brand volume but also with consumers’ secondary purchases and user reputation, which can highlight product competition. The force factor, 352 environmental protection is precisely the data that gives a bright eye on these factors.
Shuffle is inevitable
The mature development of any industry is inseparable from three stages: panic buying, comfort buying, and rational buying. Perhaps the vast majority of consumers in China have not yet reached the stage of rational purchase, but this does not stop the trend of the industry to shuffle.
At least for now, there have been three incentives that are not conducive to “speculators”:
1. The new air net regulation will be introduced soon, or the standardization of the empty net market will be accelerated. According to media reports, the two industry standards of “Filter Filter for Air Purifier” and “Electrical Dust Filter for Air Purifier” have entered the final stage, and are expected to be officially introduced in 2018. Different from the “new national standard” that pays attention to the overall energy efficiency standard, the two new standards have more detailed specifications on the filter life and purification capacity and also mean that the technical threshold of the industry is once again improved.
2. Market resources began to tilt, and the entry threshold for empty-net markets increased. At present, the domestic net air market has formed a three-pronged pattern, namely, the household appliance giant represented by Philips, the Internet cross-over represented by Olansi, the professional air net manufacturer represented by Yadu and 352 environmental protection technology. In addition, Gree, Midea, TCL, and other comprehensive appliance giants are also entering the empty net market, leaving opportunities for emerging Internet brands increasingly narrow.
3. The homogenization of the empty net market and the proportion of hidden competitiveness increased. Like mobile phones and air conditioners, air purifiers are also facing the convergence of appearance and technical parameters, especially the entry of a large wave of OEM OEMs and Internet brands. The value of dominant competitive factors such as technology and products is weakened, brand and supply. The hidden factors such as the chain and the internal optimization ability of the enterprise will influence the final pattern of the industry. For example, it is not the air castle that is famous for the implantation of “Ode to Joy”, nor the old company such as Yadu, but the 352 environmental protection technology that is not known because of its products, technical barriers, and supply. The advantage of the chain end.
In addition, with the maturity of consumers’ awareness of empty-net products, they are also testing the full strength of the manufacturers. For the 352 environmental protection technology that has just received financing, it has begun to launch a small space air purifier X50 for small-sized or shared people. The footprint is similar to that of an A4 paper. The CADR value of the particulate matter is still higher than the general air purifier on the market, taking into account the dual elements of the volume and performance of the purifier, and fully taking into account the strict requirements of the small space for mute, basically do Go to “No Disturbance Mode”.
Air purifier “remove formaldehyde 99%”? Don’t believe it, it’s all flickering!
“Removal of formaldehyde 99%” “Efficient addition of PM2.5”… In the past two years, due to the influence of smog, air purifiers have been increasingly popular, and the effect of products with 5,000 or even 10,000 yuan is really publicized. Is it amazing?
Recently, the relevant performance evaluation results of China’s air purifiers released by relevant departments show that the PM2.5 technology in the air purifier purifying air is relatively mature, and the function of scavenging formaldehyde is basically “flickering”, with no significant effect, and the price is high and exaggerated. And so on.
Remove formaldehyde by 99%? Just selling
The reporter saw at the air purifier counter of the front store of an electrical appliance store in Beijing that there were twenty or thirty air purifiers on the shelves, and the price ranged from less than 1,000 yuan to nearly 10,000 yuan. Many manufacturers’ large posters are printed with “99% formaldehyde removal”, “complete decomposition without residue”, “smart removal of formaldehyde”, etc., and various “advanced technologies” with letters and English are attached below.
The reporter asked about the need to purify the air after the house was renovated. The salesperson immediately promoted an imported brand air purifier with a price of 5,499 yuan. In the promotional materials, this model AC4076 products filter formaldehyde rate as high as 99.1%.
The reporter asked the clerk “when the effect can be achieved so well, how the value is drawn”, the clerk said that “this is imported, all the data detected by the authoritative laboratory, authentic and reliable, just use it.”
So, the actual use of formaldehyde in addition to the effect is really so ideal? Song Guangsheng, director of the National Indoor Interior-Environment and Environmental Product Quality Supervision and Inspection Center (hereinafter referred to as “Indoor Environmental Inspection Center”) gave a rather pessimistic answer: “Most air purifiers claim that formaldehyde has almost no effect.”
It is understood that the indoor environmental inspection center selected ten purifiers on July 23 and conducted a one-month test. According to the test report, seven out of ten purifiers have the function of purifying formaldehyde. According to the results of the measured cleanroom air (CADR), these seven purifiers have no significant effect, including the similar products of AC4076. AC4074. The best-performing one purifier is turned on for 1 hour in a 15 square meter room. In theory, the formaldehyde in the air is also reduced by less than 50%, and the CADR value is only 29m3/h.
“Generally, the CADR for removing pollutants is worth more than 60m3/h. The effect is even worse when formaldehyde is released indoors. Most air purifiers claim that the effect of removing formaldehyde is only a selling point.” Song Guangsheng said.
The best value for a thousand yuan purifier
It is understood that the national standards for air purifiers stipulate that their performance indicators are expressed in terms of “clean air volume” (CADR) in m3/h. The air purifier has a corresponding CADR value for each air pollutant that can be removed. The CADR value can directly and scientifically reflect the true purification ability of the air purifier. The larger the value, the stronger the ability.
Because the effect of the air purifier is difficult to visually verify, there are few products with more professional CADR values, which leads many people to choose the air purifier. Liu Lin, a citizen, said: “I can’t tell the effect of a machine. In this case, for the sake of peace of mind, I can only buy a relatively high price.” The reporter found that Liu Lin’s idea is quite representative.
Air purifier, is it really the higher the price, the better?
The test results of the “Indoor Environmental Inspection Center” gave the answer: the purification performance and the price level have nothing to do with it. The reporter saw in the statistical results of the test results that the price of a foreign brand product with the highest price was 4047 yuan, the CADR value of PM2.5 ranked fourth, but the price/performance ranking ranked the last; the lowest selling price was a 499 yuan air. Purifier, the CADR value of PM2.5 in the test is 110m3/h, and the price/performance ratio is ranked second.
From the test results, the high-efficiency filter to purify PM2.5 technology in indoor air is very mature. The ten air purifiers involved in the test are basically high-efficiency filtration technology, and the CADR of nine sets are above 100m3/h. Air purifiers are effective in purifying particulate matter in indoor air.
According to industry insiders, the cost of purifiers is not high, but the price is not uncommon in the seven or eight thousand yuan. The phenomenon of high prices is more serious. “To be reasonable according to the size of your room, this inspection effect, the purifier cost of about 1,000 yuan is the best.” Song Guangsheng said.
No authoritative testing agency
In the first half of this year, sales of air purifiers nearly doubled and the market prospered. Behind the prosperity, the chaos in the air purifier market cannot be ignored, and it is suspected of false propaganda and blind expansion. The reporter saw a third-party test report on some air purifier brand brochures, and most of the products only had their own propaganda.
In the above AC4076 product brochure, the “99.1%” result is to inject formaldehyde into the “1m3 closed box, start the action for 3 hours, and determine the concentration change of the components.” The data were tested according to a third-party testing agency and the Guangdong Provincial Microbial Analysis Center.
The reporter contacted the Guangdong Provincial Microbial Analysis Center to inquire about the air purifier testing. The staff sent a “trust check registration form” and an “air purifier quotation” to the reporter. The quotation shows the CADR value (particulate matter), CADR value (formaldehyde), formaldehyde, benzene, and other testing items. The price ranges from 500 yuan/time to 2500 yuan/time. “You are free to choose the project you are willing to test.”
Experts said that air purifiers do not have an authoritative testing mechanism. It is inevitable for enterprises to detect certain data according to their own choices and even exaggerate the purification effect. In addition, the third-party testing units are mixed, which is easy to do with commercial interests, and it is difficult to ensure the accuracy and fairness of the test results.
Experts remind that the basic requirements for the purchase of air purifiers are non-toxic, safe, and the CADR value is valid and reasonable. It is necessary to purchase products according to indoor pollutants and rooms and pay attention to the timely replacement of filter materials during use.
A lot of things can be judged by logic, including buying an air purifier and hearing the details. (But I can’t talk about logic in anything. I have been telling the logic to be killed by my wife several times because of all the troubles.)
My first air purifier was bought in 2004. Of course, it must be a Panasonic. What do I mean by that? ——Air purifier is not a smog derivative, not a PM2.5 filter. In 2004, the Chinese did not know what PM2.5 was; Air purifiers, as the name implies, are machines that purify indoor air, and indoor air pollution sources are far more than PM2.5. Japan’s PM2.5 has an average annual value of 10, but we are familiar with Panasonic, Daikin, Toshiba, Mitsubishi, and Hitachi to produce air purifiers. One of the standards in Japanese hotels is the air purifier. So, first of all, we should have a correct understanding of the air purifier.
However, after all, it is China, and China is a smashing China. The harm of PM2.5 does exist in the field. Therefore, there is nothing wrong with the purchase of air purifiers. Focus on PM2.5 only, because even in Beijing, the annual average PM2.5 concentration is around 80, and the air quality is up to 190 days. We can also play the role of air purifier in the absence of smog. The value of this money is spent!
1, in the choice of brand, try to choose those familiar brands. There is nothing special about the basic functions of air purifiers, so don’t trust the so-called “professional” brands that don’t know which country to pop up. What is a professional? At best, it’s a special one. It was Matsushita. Matsushita began producing air purifiers in 1962; at that time, the CEO doors of these “professional” brands were not yet born!
[Air Purifier Science Series] Selection and Maintenance of Air Purifiers
Nowadays, the smog, decoration pollution of formaldehyde, bacteria and other hidden invisible killers around us are endangering the health of the family. As one of the most effective products for the current air environment, air purifiers have become the first choice for most families.
But in the face of a large number of products with different shapes and performances on the market, how should we choose? Please take a look at the small series below!
1. Select the purchase channel
When purchasing an air purifier, it is recommended to purchase it in regular channels such as large shopping malls, electrical stores, brand stores, and mainstream e-commerce websites.
2. Purchase an air purifier according to your actual needs
At present, the air purifier brand, function, performance, design, and price are very different, 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.
However, in the case of an air purifier, the purifying function is the most important function. If your requirements for indoor air purifiers are based solely on improving indoor air quality, you can choose a type that simply purifies the air and is cost-effective.
As people’s needs for quality of life increase, the demand for air purifiers is no longer simply to purify indoor air. For example, those who work in a closed air-conditioned room, because the air conditioning dehumidification makes the air in the room very dry and the skin becomes dry, so when choosing an air purifier, you will choose a skin-friendly function. Humidifying air purifier.
People who have been in a lot of people for a long time and have high indoor pollution need to breathe fresh air without bacteria. When purchasing an air purifier, they will prefer a small air purifier suitable for desktop.
People who drive frequently should choose car air purifiers to purify various car odors and even ease driving fatigue.
3. Is there a scientific purification principle to achieve an efficient air purifier effect?
There are five internationally accepted principles of air purification, physical, electrostatic, chemical, ionic and composite. In general, physical purification is the most common and effective method. For example, dust, pollen, allergens, viruses, and other large particulate matter can be filtered by HEPA technology in physical purification mode; while harmful substances such as benzene, toluene, formaldehyde, and other odors can be adsorbed by activated carbon in physical purification mode. Purification.
The strength of the purifying capacity of the air purifier is mainly determined by the applicable area and the amount of clean air (CADR: the rate of clean air provided). The relationship between the two is applicable area = CADR × 0.12. The ability to purify other contaminants should be combined with the applicable area.
4. Are the energy efficiency ratio, energy efficiency rating and ozone emission reasonable?
Air purifiers are usually used continuously for a long time. The energy efficiency ratio is an important indicator for measuring the purifying capacity and power consumption of air purifiers. It is worthy of attention. The higher the energy efficiency ratio and energy efficiency rating, the more energy-efficient the air purifier is and the lower the cost of use.
Ozone as a strong oxidant has a certain purification ability, but it is harmful to the human body. The state has mandatory safety requirements for the amount of ozone released from air purifiers, limited to ≤ 5 × 10 – 6% (ozone has a fishy smell).

Like the water purifier, the air purifier needs to be cleaned regularly, and some need to be replaced with filters and filters to maintain its purification effect. The maintenance and maintenance of the air purifier depend on different types of air purifiers.
The primary filter in the air purifier should be cleaned frequently. Generally, it should be cleaned once every half month. When using a vacuum cleaner or a clean brush, when there is more dust on the fan and electrode, it should be removed. Generally, it should be repaired once every six months. The long hair brush can be used to remove dust from each electrode and wind blade. When the air purifier is not in use, it should be cleaned and put into the box and stored in a ventilated and dry place. Attention should be paid to moisture protection to avoid the use of efficiency or damage due to moisture.
1. The front filter (usually the back cover of the chassis) takes a long time to collect some dust, which affects the air intake and affects the air purification effect. Therefore, it is necessary to use a vacuum cleaner to suck the dust away or use a rag to clean it, or even wash it to dry.
2. Filter net, part of the filter net needs to be taken to the sun at the end of the sun, and the purification efficiency can be better maintained, such as activated carbon filter.
3. Deodorizing filter, a deodorizing filter for a few air purifiers, to achieve the technical level of water washing, can be washed by water, that is, to maintain purification efficiency, and extend the cycle of the filter.
4. The ion generator is generally built-in and does not need to be cleaned. The better ionizer has higher working efficiency.
