Air purification engineering also known as air purifier, air purifier, air purifier, purifier, filter name, refers to the adsorption, decomposition or transformation of various air pollutants, can improve indoor air quality, improve the living and working conditions, improve air cleanness, enhance physical and mental health products.
The common air purification technologies in air purification engineering are photocatalyst, activated carbon, electrostatic dust collection, HEPA high efficiency filtration, negative ion generator, etc.. The existing air purifiers are mostly composite type, that is, a variety of purification technologies and materials are used simultaneously.
1. Clean air volume
The purification capacity of air purifier is mainly determined by the applicable area and clean air volume of particulate matter. The purification capacity of other pollutants should be combined with the applicable area.
2. Filtration performance
Filtration performance refers to the ability to filter suspended particulates in the air and to filter out the chemical gas in the house.
Certification testing of 3 and third party independent units
Is product performance certification certified by third independent units?.
4, filter service life
In addition to the efficiency of filtration, the filter should also consider the service life. Although some filters have high filtration efficiency, they have high resistance, low energy efficiency, easy plugging, short service life and relatively high cost of follow-up maintenance.
5. Energy efficiency ratio and energy efficiency grade
Air purifier is usually used for a long time, energy efficiency ratio as an important indicator to measure the purification capacity and power consumption of air purifier, worthy of attention.
