The air purifier is mainly composed of motors, fans, air filters and other systems, and its working principle is: the motor and fan in the machine circulate and flow indoor air. After the polluted air passes through the air filter in the machine, various pollutants are removed or adsorbed, and the air is continuously ionized, generating a large number of negative ions, which are sent out by the micro-fan to form a negative ion gas stream. So as to achieve the purpose of cleaning and purifying the air.
Purification principle of passive adsorption filtration (filter purification)
The main principle of the passive bedroom air purifier is: the air is pumped into the machine by the fan, and the air is filtered through the built-in filter, which can mainly play the role of filtering dust, odor, toxic gases and killing some bacteria. The filter is mainly divided into: particulate matter filter and organic matter filter. Particulate matter filter Air purifiers are divided into coarse filters and fine particulate matter filters.
The quality of the fan and filter of such products determines the effect of air purification, and the location of the machine and the layout of the room will also affect the purification effect.
Active purification working principle (filterless type)
The fundamental difference between the principle of active air purifier and the principle of passive air purification is that the active air purifier gets rid of the limitation of fan and filter, and is not passively waiting for indoor air to be pumped into the purifier for filtering and purification. Instead, it effectively and actively releases purification and sterilization factors into the air, and through the characteristics that the air will spread, it reaches all corners of the room to purify the air without dead ends.
The technology of purifying and sterilizing factors on the market mainly includes silver ion technology, negative ion technology, low temperature plasma technology, photocatalyst technology and net ion group ion technology, etc. The biggest defect of this type of product is the problem of excessive ozone release.
