Certified sealed brand-new pack of KN95 (GB2626-2006) 3D masks with breathing valves. Each mask is individually sealed. These masks are black and feature 7 layers over the traditional 4. The 7th layer consists of activated carbon for extra filtration and purification.

Both KN95 and N95 masks use multiple layers of synthetic material to protect you from outside particles. And, as their names suggest, both must filter out 95 percent of particles that are 0.3 microns in size or larger. The GB2626-2006 is an approved standard that is recognized by Health Canada, the FDA and CDC.

Features a breathing valve that makes breathing more comfortable and reduces resistance.

Layers (outside to inside): - Isolation layer to block particles - Activated carbon layer - 2x Moisture proof filtration cotton layers - 2x KN95 filtration cloth layers - Skin-friendly non-woven fabric

The mask also features soft airtight padding around the part where your nose touches the mask to ensure a tighter seal with no gaps, and to increase comfort.

No formaldehyde.
