First, the principle of passive adsorption filtration air purification

Passive air purification is the use of fans to pump air into the machine, through the built-in filter to filter the air, mainly to play the role of dust, odor, disinfection and other functions. The filter screen air cleaner uses HEPA filter + activated carbon filter + Photocatalyst (cold catalyst, far catalyst) + UV disinfection

Poison + electrostatic adsorption screen and other methods to deal with air. The HEPA filter filter dust particles and other activated carbon is mainly odor absorption effect, therefore, can be seen on the market with a fan filter, photocatalyst, ultraviolet, electrostatic and other various labels, seemingly confusing the air purifier with the basic working principle is the same, are passive the adsorption type air purifying filter.

Two. The principle of active air purification

Active air purification principle and the fundamental difference lies in the principle of passive air purifier, air purifier active to get rid of the fan and filter restrictions, not passively wait to be pumped into the indoor air purifier filter and purify, and then through the fan discharge, but effective and active released to the air purification and sterilization factor, through the air diffuse, reach each corner of the room air purification hassle. The active purification technology in technology is mainly using negative oxygen ion as purification factor to treat air and ozone as purification factor to deal with two kinds of air. These two are typical air purifiers that operate on the principle of active decontamination.
