Face Mask Black Disposable with Breathing-Valve 10 Pack | Black Face Masks for Men and Woman 5 Layer | Disposable Face Mask for Protection | Breathable Sport Face Mask Lightweight Comfortable on Skin

Works and easy to exhale thanks to vent - wouldn't wear if I was sick due to exhaust vent. But if well, great comfort for long times using - like an airline trip or working in a dusty environment.

In terms of fit, dust leakage around the side of this N95 mask, and durability this is a better quality filter mask than the ones I have used in the past.The construction of this mask is a bit different from others of this general type. Most masks of this type have little depth. But This one is thick and has two part construction in depth. The surface of it is rigid on the outside. The interior of it is softly compliant. The springy exterior of it keeps the straps from pulling out, keeps the valve where it needs to be and holds the mask shape. The interior is soft, follows the curves of my face and wicks away sweat. The compliant, soft surface of the interior is perhaps the most important feature of the design both in terms of the fit and in preventing from dust from working its way around the side of the mask into your nose and mouth.The breather valve has been added to reduce the effort in breathing through the mask which is positioned to guide your breath away from your glasses. On all sorts of levels this mask has been carefully thought through both in design and construction.

They are nice masks for a woman or a child, but a little small for a grown man. They hurt my son's face and he says they are too tight for him.

I like N 95 but with asthma, they are hard to breathe when wearing. So I like the valve!Thank you

Fits snug. Works like a regular mask. Doesn't restrict air flow. However, it's a little tight and hurts my ear if worn for a long time. Also, the strap often breaks where it connects to the mask... needs better glue!
