I love these masks! I teach in them, and they were the best when we were teaching during covid because you can breath well, they are less constricting, and they still cover all around your mouth. They're so comfortable. I tried about 6 different types of masks and this one is my top pick.

These seem to be good masks, i.e. sturdy and well-fitting.

Our chorus recommended this mask during our rehearsals through the later half of the pandemic. They are great, because they allow one to take the deep breaths needed to sing. No sucking in the mask into your mouth! They stay in place and offer good protection as well. My glasses did not fog. The only downside is that the loops are a bit fragile and the sides of the mask at prone to break if handled too much. A good product. I would order again.

The best fitting mask in the market.

I bought this mask hoping to find a more comfortable and relaxed fit, but I found these too loose, and the adjustable loop kept sliding, and made it too big and loose on my face. The material is rough and the holes for the adjustable loop kept getting bigger and bigger. So fail all around but I thought, it’s Amazon Prime and I could return them!! But NO, I couldn’t return them AND more so, I couldn’t find anything that warned me it was not returnable when I purchased it. So think twice and BUYER BEWARE, Prime is not Prime!!

The nasal bridge metal is weak. It does not bend and nor stay close to the nose/face so it allows air to escape and scents to enter. I doubt the protection given this air leak. The mask is comfortable and I like the ability to customize the tightness. Also it is advertised as allowing your lips to have space and to talk but my lips are resting on the mask. This mask is too expensive compared to other top rated brands, so I would not buy again.
