How does an air purifier work
The working principle of air purifier
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, some models of air purifiers will install in the negative ion generator outlet (the work in a high pressure negative ion generator generates a DC negative high voltage), air ionization continue to produce a large number of negative ions, by the micro fan, forming negative ions flow to achieve clean air purification purposes.
Purification principle of passive adsorption filtration (filter cleaning class)
The main principle is: passive air purifier with fan to draw air into the machine, filtered air through a built-in filter, mainly to filter the dust, odor, toxic gas and kill some bacteria. The filter is mainly divided into: particle filter and organic filter. The particle filter is divided into coarse strainer and fine particle filter
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 market factor are the main technologies for purifying and sterilizing silver ion technology, negative ion technology, low-temperature plasma technology, photocatalyst technology and Plasmacluster ion technology, this kind of products are the biggest flaw is ozone emissions exceed the standard problem.
Double purification (active purification + passive purification)
The purifier actually combines the technology of passive purification with the technology of active purification.
