The principle of air purifier purifying smog.Air purifier

　　Simply put, it is the process in which the dirty air passes through the purifier, where PM2.5 particles are intercepted by the filter, and clean air is output. As the core technical component of the air purifier, one is the filter and the other is the fan.

　　The filter is the core of the air purifier. The current air purifier filters on the market generally only have three or four layers, and some products have five or six layers. The filter is the core of the air purifier. The current air purifier filters on the market generally only have three or four layers, and some products have five or six layers. Our air purifier adopts three-layer filter and five-fold filtration + active purification technology. The HEPA filter can absorb 99.7% of suspended particles with a size of 0.3 microns (0.3 microns is the size that is difficult to filter). The filtering effect of preventing smog and PM2.5 is as high as 99.97%, which can effectively reduce the incidence of allergies and asthma patients.

　　The larger the area of the filter screen, the greater the dust holding capacity to a certain extent, the longer the service life of the filter screen, and the higher the relative manufacturing cost. The porous structure of activated carbon provides a large amount of surface area, which makes it very easy to absorb and collect impurities. Just like magnetism, all molecules have mutual gravitation. Because of this, a large number of molecules on the activated carbon can generate a strong attraction, so as to achieve the purpose of attracting impurities in the medium to the pores.

　　The better activated carbon in the society is coconut shell activated carbon. Coconut shell carbon is the first choice activated carbon for absorbing odor and benzene series pollution. Gas phase spherical microporous activated carbon is the ideal formaldehyde adsorption carbon. Some high-end air purifier brands use this type of activated carbon to make an activated carbon layer.
