How is the Air Purifiers working, Airbus brings you to know about it...
Air purifier is mainly composed of motors, fans, air filters and other systems. Its working principle is as follows: Machine motor and fan to make indoor air circulation flow, the air pollution through the air in the machine filter after the various pollutants removal or adsorption, some models of air purifier in outlet with anion generator (anion generator of high pressure work dc negative high voltage), the air ionization, produce a large number of negative ions, the breeze fan sent out, The formation of negative ion airflow, to clean, purify the air.
Purification principle of passive adsorption filter type (filter screen purification)
The main principle of passive 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 gas and killing some bacteria. And the filter is mainly divided into: particulate matter filter and organic filter. Particulate matter filter is divided into coarse effect filter, and fine particulate matter filter.
The quality of the fan and filter screen determines the effect of air purification, and the location of the machine and the layout of the room will also affect the effect of purification.
Active purification principle (no filter type)
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 purification sterilization factors that are released into the air, the characteristics of the spread through the air, Reach every corner of the room to clean the air without dead Angle.
The technology of purifying sterilization factor 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 kind of product is the problem that ozone release exceeds the standard.
Dual purification class (active purification + passive purification)
The purifier is a combination of passive purification technology and active purification technology.
