I love these masks. I wear them daily with a filter, and I feel well protected and comfortable. They fit me extremely well, and better than a KN95. I discovered Beau Ties masks early in the pandemic and loved them, but then switched to a KN95 in response to pressure from work colleagues, only to discover that I am allergic to the material in the KN95 masks! I quickly returned to Beau Ties, and for more than a year now this is the only mask I have worn. I always wear them with a filter, and I feel very well protected. Wash after wash, these mask hold up. They are an excellent product! I have purchased multiple fabrics, and I love them all.
