KN95 Folding Respirator with Valve
· KN95 is one of the levels specified in the Chinese standard GB2626-2006, and N95 is one of the levels specified in the US standard 42 CFR 84.
The technical requirements, test methods, and protection levels of these two levels are basically the same, but they belong to different national standards.
KN95 - is a respiratory protective article published by the National Quality Supervision, Inspection and Quarantine Bureau and the National Standardization Management Committee.
It is a standard for dust protection, not a specific product name. KN95 masks are used for occupational respiratory protection, including certain dust particles ( (Such as dust, smoke and other non-oily particles) protection. The biggest feature of KN95 mask is that it can prevent droplet infection caused by patient's body fluid or blood splash.
· Wearing Kn95 masks can filter particles with an aerodynamic diameter ≥ 0.3µm and achieve an efficiency of more than 95%.
The aerodynamic diameter of air bacterial and fungal spores mainly varies between 0.7-10µm, which is also within its protection range.
