I work in an inpatient substance use treatment facility, and we have to wear masks. Beau Ties masks are the most comfortable and stylish masks I own, and since I have to wear masks daily, I own a lot of masks! The other great thing about these masks is they don't shrink when you wash them. I've purchased adult masks that are now kid's masks because they shrunk. No worries here! I add the charcoal inserts, which fit perfectly. I cannot recommend these masks enough -- I've told my entire facility about Beau Ties!
