Completely safe I purchased both the black Nano masks and white Nano masks. I prefer the white because they are individually packaged. They are the only masks that l feel completely safe wearing.

This mask doesn't fog glasses This mask doesn't fog glasses! As a musician, I need plain black masks for performances but I also wear glasses which can fog up with other masks during concerts. These don't fog my glasses up and are really comfortable. They shipped super quickly too and got here in record time.

Feel Safe While Supremely Comfortable This mask is extremely comfortable and lightweight. I feel more protected in this mask than in any other type I have, so this is what my family wears if we need to visit a doctor/hospital, or crowded public area. My only regret is the price. I wish it was less expensive so I could use it regularly instead of just higher-risk environments.

A friend introduced me to these masks… A friend introduced me to these masks on a trip we took across country during covid. I would not have survived 9 hours of airports and flights with any other mask. You are protected, can breathe and deal with minimal to no fogging of glasses. 100% worth the money.

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.
