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

Material & Layer Composition


The filtration material on the mask is an electrostatic non-woven polypropylene fiber.


5 layers filter: the first layer (outermost layer) is 50g non-woven fabric, the second layer is 25g melt-blown fabric, the third layer is 50g hot air cotton, the fourth layer is 25g melt-blown fabric, and the fifth layer (innermost layer) is 25g non-woven fabric


Nose Clip: Aluminum


Ear straps: High elastic ear strap


Approximate weight of each KN95 mask:5g




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
