[GOOD DAY]BLACK KF94 Certified SINGLE Use Dust Masks 10 pcs of Individual Package for ADULT - BLACK with Free Gift (4 Masks)

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.

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.

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.

I like these because they fit differently than the usual accordion folded masks. The shape allows you to talk without the mask getting in your mouth, and these seem to seal better on my face (both around the nose and under the chin)

Just started to use them. They are easy to breath when on and I did the match test where I tried to blow out the lit match while wearing the mask. It passed! Comfortable to wear. Highly recommend theses KF94 masks.

Having tried different masks out there, I finally settled on this one for my daily use.

For my face shape, much more comfortable than a KN95. Durable enough to wear for several days.

This is still a paper mask. Does not feel like it protects me more than the N95. It's being hyped up as the next best thing. I feel it's a big let down. While I wear these out, it has air pockets on the sides of face. I feel the need to double mask with these, a regular paper mask under, then this one on top. You do it the other way around, you cant wear both.

Son muy buenas mascarillas, el pero que les pongo es que, huelen mucho a solventes, no creo que sea sano el estar respirando dichos olores ...

Son más cómodas que los cubrebocas normales kn45 , creí si fuesen un poquito más grandes serían más cómodas pero aún así me ajusto bien y estoy confirme , también el echo que viene c/u en su empaque sellado me da más confianza , en general creo fue buena compra

Son pequeños a pesar de ser de adulto, he utilizado otros KF94 que hay en el mercado y son mas comodos.
