How Does Air Purifier Work
The air purifier is mainly composed of a motor, fan, air filters and other system components, its working principle is: motor and fan machine in the indoor air circulation, polluted air through air filter machine after various pollutants removal or adsorption, the air is not cut off from a large amount of negative ions, by the micro fan sent to form negative ions flow to achieve clean air purification purposes.
Purification principle of passive adsorption filtration (filter cleaning class)
The main principle of the passive air purifier is that the air is sucked into the machine by the fan, and the air is filtered through the built-in filter screen, which can filter dust, odor, poisonous gas and kill some bacteria. The filter is mainly divided into: particle filter and organic filter. Particulate filter air purifier is divided into coarse effect filter screen and fine particle filter screen.
The quality of the fan and filter screen determines the effect of air purification. The location of the machine and the layout of the room will also affect the purification effect.
Active purification principle (no filter screen type)
The fundamental difference between principle and active passive air air purifier purification principle is that the air purifier active to get rid of the fan and filter restrictions, not passively wait to be pumped into the indoor air purifier for filtration and purification, but effective and active released to the air purification sterilization factor, characterized by air the diffusion of indoor air to reach every corner of dead without purification.
The main technologies for purifying sterilization factors in the market are silver ion technology, negative ion technology, low temperature plasma technology, photocatalyst technology and net ion group ion technology. The biggest defect of this kind of products is the problem of excessive ozone release.
Double purification (active purification + passive purification)
The purifier actually combines the technology of passive purification with the technology of active purification.
