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.

Love these masks and made in USA Love these masks. Sturdy and stylish, easy to wear and avoid glasses fogging. Fast shipping, and LOVE they are made in USA. Pricey but worth it. Have ordered several times to share with family and friends. Prefer the classic Nano in black with subtle logo over the new brand, so hopefully they remain available.

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.

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.

The best mask is Nano Air Mask I have been wearing the Nano Air Mask for about 7 months now. I wear them at work at my Customer Service Job, when traveling and out and about. My voice is not muffled, my glasses don't fog, there is room for my mouth and lips to move around, and with my hot flashes they are still the best masks that I know of. I've started sharing these masks with family, friends, and coworkers and now they purchase them. It's a good secret you want to just keep to yourself but cant. When I know a good thing I have to share.
