The air conditioner filter element is generally located behind the auxiliary storage box, which is the first pass of the outside air into the car, just like the human lung. Its function is to filter the particles in the air, such as dust, pollen, soot, industrial particles, nitrogen oxides, etc., to keep the air clean.
Air conditioner filter element is generally divided into three kinds: filter paper type filter core, activated carbon filter core, HEPA filter core.
The filter core is made of filter paper or non-woven fabric, forming a thickness by folding to increase the filter area. This material filter can only filter the general particles, and formaldehyde, PM2.5 and other harmful substances do not have much effect. Most cars use this filter because the air is large and cheap.
The activated carbon filter core is added with a layer of activated carbon on the filter paper material, which can absorb formaldehyde, odor and moisture. But it still has no effect on the rampant PM2.5.
HEPA is a newly developed new filter cartridge called High Efficiency Particulate Air filter, which means "HEPA particulate air filter"". It filters efficiencies of 0.3 microns in diameter (PM0.3), which is said to be up to 99.97%. To put it bluntly, HEPA is specifically dealing with PM2.5 and haze.
Each of the three filters has characteristics, and the more functions it is, the more money it will cost. You can according to their own Baidu car environment of their choice. Relatively speaking, the owner of the Volvo installed HEPA package, Tesla owners can save.
