I think good purifier can purify subtle grain substance.
The size of grain content indicates with PM2.5 commonly, the meaning of this size is the hair silk diameter of 1/20. General purifier can satisfy the function that purifies PM2.5.
Purifier industry describes less than PM2.5 grain commonly, with PM2.0, PM1.0, PM0.5, PM0.3 will express, of the HEPAfast mesh of li of face air purifier filter efficiency uses PM0.3 to make a standard commonly, purify efficiency for instance for 95% , the grain content that can be aimed at PM0.3 with respect to the mesh that is purifier filters efficiency is as high as 95%
Inside purifier product, still have filter purify a technology to be able to reach less grain, it is OK that at present the market still had a few purifiers to had been accomplished filter the grain of PM0.1.
At present till, air purifier industry filters the technology is best should become the CHEPA technology that belongs to American brand Airgle, this history on the most arrogant CHEPA technology filters precision is highest and OK achieve 0.003um, filter efficiency can be achieved 99.999% , it is current on the market filter precision is highest the 33 times above of 0.1um, filter efficiency is the HEPAfast on far supermarket field more.
Fiercer is the special purifier brand that this brand is pitch on of sand spy royal family, estimation also is the actual strength that took a fancy to this brand purifier. I see a few relevant pictures in news, turn to everybody to look together here.
