Nanofiber Filter Mask: Fold-Flat Dust Mask 10PCS + Free 3D MASK

Not good! Don't recommend.

These masks are very comfortable to wear. Their design allows the mask to completely cover my lower face (including my jaw). They are light weight and well made. I've ordered several sets over the course of the last year and a half.

Love them. Easy to use and put on.

Comfortable, safe, easy to breathe very portable/foldable. Safer and more effective than the basic ones.

I brought these for protection against airborne pathogens. Did a little unscientific test. Picture 1 shows mask wet with vacuum cleaner dust and pics 2 shows what I would breathe (literally NOTHING). You MUST stock these masks back!! $1.18 per mask well worth it
