Fast shipping. Great quality, light weight, and comfortable mask. What I love the most, it offers almost the same level of protection as N95 and it claims to be re-usable (still testing it) as you can clean it. The re-usable, cleanable part is the one that get my attention. I am a nurse and I re-use my N95 (not really nice, but no choice). It would be a wonderful thing to have protective respirator mask that is cleanable and reusable. However, I buy this mask for personal use. I have re use them...
