In the standpoint of filtration efficiency, this common is predicated within the classification of filter components
And the extent, as well as the detection method, stipulate the filtration efficiency of every product
(See Table 3 ).
Also, GB 2626-2006 has general necessities, Visible inspection,
Leakage, breathing resistance, exhalation valve, dead Room, subject of view, headband, connection
And connecting areas, lenses, air tightness, flammability, cleansing and disinfection, producing
Technological specifications including data and packaging that ought to be furnished by the company.

At the moment, the new normal is introduced to The entire society free of charge②. In The brand new common
Additional 7 conditions which include "aerodynamic particle dimensions" and revised some

This normal is especially applicable to the air air pollution atmosphere in way of life
The protective mask worn to filter out particles, although not ideal for clinical
Use and also other Unique industries.
With the perspective of phrases and definitions, the particulate matter specified in this conventional is a ring
Ambient air within an aerodynamic equal diameter considerably less two.5 [mu] m of particles
Particulate subject, also called great particulate issue ( PM2.five ), is the same as other standards in the following paragraphs
The definition of particulate make a difference differs.
In the viewpoint of filtration performance, masks might be divided into: Course I, Class II ,
Class III , the corresponding saline media filtration performance is 99% , ninety five%
