KN95 Mask for Epidemic Prevention and Control

Never thought of, in 2020, due to the global spread of the virus, the new champions league KN95 and N95 became popular vocabulary. In masks to become tight supplies worldwide, people around the world all kinds of masks differences KN95 Mask for Epidemic Prevention and Control confusion, especially widely used KN95 and N95 mask. But traced back, understand the mask standard, you will understand the mask.

KN95 mask according to the Chinese standard GB 2626-2006 "respiratory protective equipment self-priming prevent particulate respirator filter type", filtering element according to the filtration performance can be divided into two KN95 Face Mask categories, KN and KP, KN is suitable for filtering the oily particles, KP class is suitable for filtering oil and non oily particles. According to the filtration efficiency level, level of filter element, masks, can be divided into KN90 KN95, KN100, KP90, KP95, KP100 six categories, including comprehensive cover excluding KN90 and KP90). KN95 mask is for oily particles filter efficiency reached more than 95% of the self-priming type prevent particle respirator.

N95 respirator according to NIOSH - 42 CFR Part84 of federal regulations of respiratory protective equipment standard authentication appendix K - filtering wave particle filter. Appendix K filters can be divided into self-priming filter type anti particulate respirator and supply air filter type prevent particle respirator. Self-priming filter wave particle filter element according to the filtering performance is divided into three categories, N, R, P, N type suitable for filtering the oily particles, R and P class is suitable for filtering oil and non oily particles. P type filter element use longer time limit than R class, R class filter elements, 1 working day use time is commonly P class can be based on demand by the manufacturers recommendations. According to the filtration efficiency level, level of filter element, masks can be divided into the N95, N99, N100; R95, R99 R100; P95, P99, P100. N95 mask is for oily particle filtration efficiency reached more than 95% of the self-priming by filtering particle respirator.

So, will tell from the concept, KN95 and type N95 Quickly Delivery Disposable Protective Clothing masks are for non-oily particle filtration efficiency reached more than 95% of the self-priming by filtering particle respirator. Since the same concept, two masks assessment indicators are consistent? ???? KN95 differences with N95 key evaluation indexes at present, our country KN95 type mask detection is based on GB 2626-2006, and the evaluation index of the N95 have certain differences.

Overall, KN95 type mask than N95 mask to ask for more, integrated demand higher! On July 1 this year, GB 2626-2019, type of KN95 masks in respiratory resistance, air tightness and practical performance, cleaning and disinfection, etc, put forward higher request, can reflect more masks in the process of using the actual performance, as a result, both the new standard and old standard, as long as meet the standard requirement of KN type 95 masks battle type N95 mask, no problem!
