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.

I love these masks I love these masks. They are well made, comfortable for all day use. They are probably too well fitted for those who must talk for a living, but looser masks feel unsafe all the rest of the time. I keep headband style tensioners around when I need max security, but most of the time I just wear them and feel safe.

These are the best masks I have found These are the best masks I have found. Comfortable and feels very secure. Customer service is outstanding.

COST!!!! COST!!!!! We have to order a months supply at a time. My wife is a severe asthmatic, and cannot NOT use the Chinese made KN95 masks due to air flow restrictions PLUS every time she has attempted to use a Chinese KN95 masks she has immediate skin reaction and immediate sinus infection and restricted airflow. So the Nano Air Mask is the only true protective mask she can use, which estimated cost at current pricing is $1200 per year for her masks alone. Due to being high risk category persons we have to use masks and gloves when out in public, which costs hundreds of dollars to keep supplied and safe. Tough to do when you are on a fixed income and medically not allowed to work any longer. Wife is an RN with Adult onset Asthma, and I'm a Respiratory Care Practitioner both with 40 years experience each.

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.
