Common Sense N 95 /KN95/FFP 2 masks

 

 

masks, once relegated to specific professions, are quickly becoming commonplace.

 

N: This is a Respirator Rating Letter Class. It stands for "Non-Oil" meaning that if no oil-based particulates are present, then you can use the mask in the work environment.Other masks ratings are R (resistant to oil for 8 hours) and P (oil proof).

 

95: Masks ending in a 95, have a 95 percent efficiency. Masks ending in a 99 have a 99 percent efficiency. Masks ending in 100 are 99.97 percent efficient and that is the same as a HEPA quality filter.

 

3 microns: The masks filter out contaminants like dusts, mists and fumes. The minimum size of .3 microns of particulates and large droplets won't pass through the barrier.

 

Standards: N 95 mask are considered functionally equivalent to certain mask regulated under non-U.S. jurisdictions, such as FFP 2 mask of the European Union and KN95 mask of China. even slightly different criteria are used to certify their performance, such as the filter efficiency, test agent and flow rate, and permissible pressure drop, our mask can meet all the standards

Test-result-of-filtering

Even if our mask is used for 12 hours, it can still maintain at least 98% filtration efficiency, but as particles continue to adsorb and settle on the mask, the respiratory resistance will become greater and greater.Respiratory-Resistance-1
