Masks are made with FDA approved silicone. Adjustable elastic ear bands and soft silicone create a comfortable seal on your face. There is no blowback to your eyes or glasses when expelling air therefore no fogging while worn with glasses. The shape of the mask creates distance between your mouth and the mask so you can speak clearly and not have material on your lips. You can hand wash, boil, or place in the dishwasher to sanitize. The silicone mask is very flexible which allows for extra comfort, and comes with 10 replaceable KN95 filters. Filters are suggested to be replaced after 48 hours of usage.
Large:One size fits most adults men and women.
Cleaning options: Dishwasher safe, Boil, or hand wash with soap and hot water.
