Working Principle Of Air Purifier
In fact, although the market declared the name of the air purifier, type, function is not the same, but the trace to the roots, from the air purifier working principle, the main is nothing more than two kinds: one is passive adsorption filter air purification principle. Passive air purification, is the use of air blower to pump into the machine, through the built-in filter screen air, mainly to filter dust, odor, disinfection and other functions. This kind of filter-net Air Purifier uses HEPA filter Net + Activated Carbon filter Net + photocatalyst (cold catalyst, many far-touch medium) + ultraviolet disinfection and disinfection + electrostatic adsorption filter to deal with air. The HEPA filter mesh has the function of filtering dust particles, other activated carbon and other main adsorption odor, therefore, it can be seen that the market with fan filters, photocatalyst, ultraviolet, static electricity and other different labels, seemingly chaotic air purifier adopted by the basic principle of the same work, are passive adsorption filter-type air purification. The second working principle is the principle of active air purification. The fundamental difference between the principle of active air purification and the principle of passive air purification is that active air purifier to get rid of the limitations of the fan and filter, not passively waiting for indoor air to be pumped into the purifier for filtration purification, and then through the fan out, but effective, active release of purifying bacteria in the air, Through the characteristics of air diffuse, to every corner of the room to the air without dead-end purification. At present, the technology of active purification is mainly using negative oxygen ions as purifying factors to treat air and using ozone as purification factor to treat two kinds of air. These two are typical air purifiers that work based on the principle of active decontamination.
