2018-02-28

   Air purifiers are mainly used to purify the air through physical adsorption, chemical reactions, and light wave radiation. According to different working principles of air purifiers, it can be divided into passive air purifiers, active air purifiers, and combined active and passive air purifiers. Therefore, the working principle of the air purifier is also divided into three principles of passive, active and compound purification.

 

(1) Passive: The air is fed into the filter screen of the machine through a fan, the filter screen can filter out dust, odor, toxic gas, etc., and can kill some bacteria. This is mainly achieved by the filter, and different filters focus on different functions, such as dust collection, deodorization, formaldehyde removal and HEPA filters. Among them, the HEPA filter has the effect of decomposing toxic gases and sterilizing, and is the most widely used filter before. The purification effect of this type of product is mainly determined by the function of the fan and the quality of the filter. It has the disadvantages of uneven indoor purification and high cost of replacing the filter, such as Honeywell in Europe.
