On the last day of February, the former well-known goddess issued the "Chaijing Fog Survey: Under the Dome", and the circle of friends was screened the next day. How to choose an air purifier has become the most unsettled question recently.
First of all, who needs an air purifier? Theoretically, in the day of soaring GDP every year, it is necessary for residents of major cities in China to have air purifiers at home, except for a few places such as the seaside, deep mountains, and large rural areas. In particular, the low floor beside the road, the residential floor near the 20th floor (just the height where atmospheric suspended particles and toxic gases will stay), and the chemical factory/furniture factory/waste incineration plant and other air pollution sources near the home.
Then came the question of how to buy. Although the air purifier sounds very tall, and a lot of proprietary names like "anion, silver ion, enzyme, photocatalyst, CADR, HEPA, TVOC" seem to be big, in fact, air purification mainly deals with two things: 1 Particulate matter, such as: PM2.5， Sensitized pollen, bacteria, pet droppings, etc; 2. Volatile organic substances, such as formaldehyde, odor (smoke, odor), etc.
In addition to the most basic activated carbon and HEPA filter screen, there are also Sharp net ion group, Panasonic nano water ions, Daikin's ion sterilization technology (officially known as Liuguang Energy), Mitsubishi's BIO HEPA filter membrane and many other technologies that make people feel confused. However, it is worth noting that the ozone generation function in the trademark list of many domestic factories is actually a double-edged sword. Low concentration ozone can kill poison, but high concentration ozone will cause direct harm to human body.
The air purifiers available in the market are mainly divided into Europe, America, Japan and South Korea, and domestic ones. In terms of technology, European, American, Japanese and Korean brands can only be said to have their own advantages and disadvantages. However, because of different use environments (European, American and Japanese brands are usually placed in the living room), European, American and Korean brands are generally noisy; The Japanese and Korean families mainly focus on beautiful appearance, low noise and portability; The domestic products are naturally better than the cost performance.
But considering the length, let's draw a conclusion directly... Here are the recommended results:
Take it from Tuhao, the representative of commercial aircraft IQ Air HealthPro 250
Without saying a word, the strongest equipment is offered: the commercial product of Swiss IQAir AG, which uses HEPA+MULITGAS+electrostatic filter screen. The electrostatic filter screen provides strong particle adsorption capacity (PM2.5), without ozone safety problems, plus MULITGAS filter screen (active carbon+active impregnated alumina carrier).
Simple purification principle, powerful and violent centrifugal backward curved fan and high-performance motor made in Germany, 2950rpm ultra-high speed, enable it to provide an incredibly high air flow of 1325m3/h, and the purification efficiency of particles above 0.003 microns is up to 99.97%, suitable for rooms of 85 square meters and below, and the price is worth 15000
The most beautiful, Bamudaan style
The products that are famous for being copied at the pixel level even make people feel "no wonder they are copied" after seeing the original. The simple and low-key appearance covers an area of only A4 paper, and it is no incongruity to use them directly as living room decoration. In terms of filtration capacity, mechanical filtration and unique double fan structure are used to attract suspended substances far away from the room, which can filter larger particles such as pollen that cannot be attracted by traditional air purifiers. CADR (clean air supply) is up to 496 square meters/hour. In 60 square meters of space, PM2.5 removal rate can reach 99% in 20 minutes. The activated carbon filter screen with the size of four football fields can remove odor and harmful organics in the air.

Filtration/disinfection/humidification N-I, Sharp KC-W380SW-W
It is suitable for users with various requirements, but each requirement is not too high. The machine is equipped with the humidification type net ion group technology. By ionizing the electrolytic water molecules in the humidification box, while humidification and filtering the air, negative ions are generated to sterilize and decompose harmful organics, and effectively reduce ozone production. The adsorption type air filter is equipped with four layers of filters and has strong suction, and the CADR reaches 375m3.
In addition, besides filtering, disinfection and humidification, dust, odor, humidity sensor and indicator light display are conscientiously placed to meet your N air purification needs at one time.
Price: 3499 yuan
High speed processing PM2.5, Mitsubishi SPS-511AC
This is a very simple product in function. Although the price is not low, it is still the most basic mechanical filtering structure, and the core technology and cost are almost spent on the filter element. In addition to the honeycomb deodorization filter screen, the triple filter membrane is also equipped with the BIO HEPA filter membrane, which Mitsubishi is proud of. In addition to the good sterilization function provided by the "incidental" enzymolysis technology of BIO HEPA filter membrane, the machine is almost specially designed for high-speed processing of PM2.5 particles.
The maximum CADR value of violent fan plus violent filter screen is 316m3/h, which can provide 99% PM2.5 removal rate for 10 minutes in a room of 20 square meters, and the applicable area is 42 square meters. If you really want to say that it has any major shortcomings, it must be that it is going to go overseas and has not been sold in China
Price: 3280 yuan
Decoration pollutant buster, Daikin TCK70P-T
As an old brand of Japanese purifier, Daikin's exclusive streamer energy device acts on all filters (ion sterilization technology) by releasing high-speed electrons. In addition to the function of dust removal and PM2.5 particles, it provides powerful organic matter removal ability in principle, which can bombard and decompose formaldehyde, benzene TVOC and other harmful chemicals can effectively kill harmful bacteria such as influenza virus, which is far more effective than conventional filters. It can also remove the static electricity in the air, further reducing the adhesion ability of dust and floating bacteria in the air.
The maximum clean air volume is 426 cubic meters/hour, the service life of the filter screen can reach 10 years, and the price is relatively friendly. The only thing worth noting is that the machine will produce trace ozone in principle, but as long as it is not placed beside the bed, its impact will be minimal. If the house is newly decorated, or there is a furniture factory or chemical factory nearby, it will be a good choice.

Low demand entry level, Panasonic F-PDF35C-G
Living by the sea or in the south, worried about the air quality and the budget is insufficient, but still can't trust the domestic brands? Well, this is almost a work of conscience tailored for cost performance. With the classic mechanical filter structure, the broken activated carbon can deal with conventional pollutants such as PM2.5, formaldehyde, odor, bacteria, etc., and the working noise is controlled between 18-44 decibels. There is no problem if it is placed in the baby room, and the applicable area is 45 square meters. In addition, the filter screen that can last for three years also greatly reduces the cost of later maintenance, which is cost-effective.
Price: 799 yuan
Although there are a lot of things mentioned above, the most direct and permanent way is to move to the seaside in the south. There is a spectrum of poor air there
