I like this mask a lot. I'm a healthcare worker and use masks like tissues. I like this because it is the one mask where it does not cause me to break out. It is great for sensitive skin. It also lays nicely on your face and is adjustable. It does not hurt my ears. I highly recommend this mask.

These are as comfortable as they get and seal well.

I can’t stress how much I trust 3M products. And this product is a true testament of that. I use them when I travel on airplanes or am cleaning out a dusty part of my home. They fit very snug to my face and let no air pockets in on either side. Super lightweight and durable and as always with Amazon offered at an excellent price.

I bought these in advance of my first trip out of down since the pandemic hit. The quality is great, as expected, though I felt like the size of the mask itself was a bit small for my face. This was only noticeable when I was talking while wearing the mask. The bottom would roll up as my mouth moved, and I'd have to touch it to bring it back down. If you have smaller facial features, these will be great. I still like them and would use them again, but I do wish they were a touch larger.

Working with the homeless population, this product is perfect.

They fit snug and securely, and are comfortable enough to wear on a long flight. I’m one of those unfortunate people who gets a headache from wearing masks that loop behind my ears so these have been a fantastic alternative.

These are good masks. A bit expensive but that’s to be expected with quality like 3M.

This is not a mask I'd wear for an extended period of time to do any sort of work in. The Good The mask itself is comfortable especially for a small face. I like the padded nose clasp. The Bad The smell is horrible and very chemically. Wearing it for 15minutes made me nauseous. The rubber bands starts to pull on the back of the neck immediately. I have shorter hair so I don't know how uncomfortable the rubber bands are if you have longer hair.

Masks are a bit pricey nowadays, especially with inflation going completely insane. But these masks are so much more comfortable than the "round" 3M masks you can purchase. The elastics on these are not so painfully tight, and they have a bit of extra room on the inside, allowing you to breathe better. Other masks are so tight and painful to use, they actually left cuts and abrasions on the bridge of my nose. This is the mask I'd recommend for travelling on airplanes, since it can be worn for a very very long time with relative comfort.

Muy buenos, casi perfectos (son 4 capas nada más) pero su comodidad y tras aprobar todas las pruebas "comunes" te hacen sentir seguro al usarlas, aún en espacios muy concurridos. Sus elásticos no fallan, pero sí causan presión hacia tu cara para mantener un ajuste perfecto. No llega a lastimar, ni siquiera por uso prolongado. El talle va bien a caras chicas y grandes (mis hijos de 9 y 10 años no tuvieron problema alguno al usarlos. El respirar no se dificulta en absoluto, tampoco se genera humedad en la cavidad y, por ende, no hay problemas de irritación. Quienes suelen dejarse el vello facial les parecerán grandiosos estas mascarillas. Lo único negativo es su precio, cuando por mucho menos se puede acceder a mascarillas de misma y hasta mejor calidad con certificaciones iguales o similares.

Muy buena calidad

Nous l’utilisons pour la coupe du béton et il fait bien le travail et est très confortable

I deducted a star as I could not fit the mask properly as per instructions. When mask is placed correctly there is a "breath test" at the end to determine if safely protecting. I could never pass a "breath test". Maybe because I'm petite I'm not "one size fits all"?
