    They work
  

*by P***Y on Reviewed in the United States on February 7, 2021*

These fit well and are comfortable.As far as their efficacy, everyone in my workplace got covid except me. (That's confirmed by testing, I'm not guessing.) I wore each mask for 5-7 days. That's a pretty low daily cost to stay healthy.

    Don’t Listen to the Nay Sayers
  

*by L***A on Reviewed in the United States on February 7, 2021*

Surprisingly this Mask fits both my smaller face & my husband’s bigger face perfectly. On both of us the sides completely Lock into the sides of our face, ample coverage for both of us including under our chins. Even the ears straps are comfortable & fit perfectly on both of us. Very Comfortable & Breathable with less fogging. They are thick & pass the light test(holding up to the light no light passes thru. Does not cling to nose/mouth puckers out a bit. We feel safer & more comfortable than our 2 layer cloth masks with filters. This mask lines up with my what online research said to look for.

    The only high-protection mask I can figure skate in!
  

*by N***E on Reviewed in the United States on January 18, 2022*

I need to skate my freestyle program--2:40 at max heart rate, with 3 spins and 5 jump passes--with a mask on, and that's after warming up the jumps, spins and sections of the program for 45 minutes first. I've managed in a 2-layer cloth mask with mask bracket for the past year and a half, but don't feel like that's enough protection with Omicron here now. Today I started my practice in one of these, first tying a knot near the end of each ear loop to customize the fit (I think they purposely make them long so you can do that). I figured I'd switch to my usual cloth mask setup when it became hard to breathe. .. But it never became hard to breathe! I have tried two other KF94s as well as a KN95 and was never able to do this! I am over the moon! This brand of mask tested at 99.8% filtration according to the independent tests conducted by "The Mask Nerd, which is what made me come looking for it on Amazon.
