Masks used to be sent in individual… Masks used to be sent in individual sleeves. I do not care for all of them in one pack. They stick together and are hard to get out. The individual packaging als allowed for tossing one in school, bag, purse, car...etc.

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.

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.

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.

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.
