These are GREAT quality made in USA Vermont. I'm very impressed with the company that not only values its customers, but it's employees as well. I have bought not only masks for my husband & self, but also as gifts for my family. I recommend purchasing the filters that can be inserted into most of their masks. Right now, I'm doubling up and inserting 2 filters into our masks when we go out in public. I can't tell you how many times our masks have gone through he washer & hung up to dry, they look and perform like they did when we first received them. (Do Not was the filters!)
