Since receiving the N95 Rated Nail Dust Mask from Aerovex Systems, I've noticed a big difference in my sinuses and breathing. I also smell & inhale less monomer, polishes, and acetone. I love that the adjustable band is worn behind the head and not over the ears. The traditional surgical mask don't compare to these mesh breathable masks. I thought my purchase of the Nail Source Capture System and Salon Air Purifier from Aerovex Systems was all I needed until received the N95 Rated Airwave Nail Dust Mask. Great purchase from a wonderful company!
