The KN95 Mask is the Chinese version of the USA N95 and European FFP2 Masks.
All 3 are designed to capture at least 95% of particles 0.3 microns (300 NM) or larger.
The KN95 is make of 4 layers nonwoven fabrics. Each layer has a unique purpose
The layer construction heat sealed , not stitched, including attaching the ear loops (no staples)
The ear loops are flap shaped, not round ,which makes them more comfortable to wear behind the ears as they don't cut into the skin.
The KN95 design is soft and flexible and more comfortable to wear than the clamshell moulded designs.
This KN95 design does not have a breathing valve. A breathing valve only improves air flow. It has nothing to do with particle filtration.
