Air purifier is mainly composed of motor, fan, air filter screen system, its working principle is: the machine inside the motor and fan to make indoor air circulation flow, the air pollution through the air in the machine filter will all sorts of contaminant removal or adsorption, after the air ionization, produce a large number of negative ions, is the breeze fan out, form a negative ion airflow, achieve the goal of clean, purify air.

 

Purification principle of passive adsorption filtration (filter purification)

 

The main principle of passive air purifier is to use a fan to draw air into the machine and filter the air through the built-in filter, which can mainly filter out dust, odor, toxic gas and kill some bacteria.And the filter is divided into: particulate filter and organic filter.Particulate filter air purifier is divided into coarse filter, and fine particulate filter.

 

The quality of the fan and filter determines the effect of air purification. The position of the machine and the layout of the room will also affect the effect of purification.

 

Principle of active purification (filter free)

 

Active principle and principle of passive air purification of air purifier fundamental difference is that the active air purifier get rid of the limitation of the fan and mesh, not passively waiting for indoor air is pumped into the purifier filter purification, but effective and active released into the air purification sterilization factor, can spread through the air, and to reach every corner of the indoor no dead Angle of air purification.

 

The technologies of purifying and sterilizing factors in the market mainly include silver ion technology, negative ion technology, low-temperature plasma technology, photocatalyst technology and net ion group ion technology, etc. The biggest defect of such products is the problem of excessive ozone release.

 

Dual purification class (active purification + passive purification)

 

This kind of purifier is a combination of passive purification technology and active purification technology.
