Nano Msk has been an excellent Nano Msk has been an excellent, safe mask for us. This was our third order. It allows us to breathe for extended time while staying comfortable. The mask is only available in white, would much prefer black.

Fit could be improved Masks are pretty good and reasonably comfortable, but it would be nice if the ear loops were easily adjustable. I have to tie loops in order to tighten them appropriately; as is the mask does not form a seal and so cannot possibly perform like an N95.

DESAVO masks First time trying the DESAVO version. My husband & I really like these! Will be getting more. Covers better than any other masks we have tried.

This mask fits better than most on your… This mask fits better than most on your face. I especially like that it allows you to talk without the mask slipping down your face. The only drawback is that the sides and nose can allow air to enter/exit and if you have glasses it requires a lot of adjustment to prevent fogging. I think if you have a fuller face then that's less of a problem (air getting out around sides and top), but my face is rather thin. Overall it is very comfortable.
