Our KN95 face masks are in stock and available in 10 or 50 packs. The lightweight design of our KN95 respirator masks mean you can protect yourself from airborne particles like viruses, pollutants and allergens with comfort and ease. Each mask has an integrated nose clip and flexible ear straps to ensure an ideal fit.
The KN95 masks sold by ACS Material are manufactured in accordance with industry standards and have been systematically tested to ensure a particle filtering efficiency of at least 95% of non-oily suspended particles of 0.3 microns or larger. They provide a much higher level of protection with face form fitting and greater pressure drop. To claim compliance with the GB2626-2006 KN95 standard, these respirators must meet or exceed required physical properties and performance characteristics, which can vary according to the regulatory bodies of different countries.
A reference by 3M in a technical bulletin released in January 2020 demonstrates that the several country-specific standards used to grade the filtering facepiece respirators (FFR) tend to converge into functional equivalence (download this bulletin here). KN95 mask standards produce FFR devices that are similar enough to be interchangeable with N95 and FFP2 masks for the purposes of their use in a pandemic. All of them are good for filtering non-oil-based particles such as those resulting from bioaerosols (e.g. viruses), wildfires, PM 2.5 air pollution, or volcanic eruptions.
