Comparison of Mask Standards, Ratings, and Filtration , n95 particle filtration rate

Hi Claudette, N95 and KN95 ARE filtration rate standard. No matter how many layers do the manufacturer use in the mask, they should be racing the claimed filtration rate. An additional layer may help to increase the filtration rate, but we havent done any test on this yet.
