When worn properly, a person wearing a non-medical mask can lessen the spread of infectious respiratory droplets. The HI Community Mask from Koziol reduces the risk of infection to your self and others. It also protects the wearer from self-infection by touching the lips and nose. These adult face masks are made of a medically tested flexible plastic and can be adjusted for a secure fit with the supplied stretchable band. The Community Mask can be cleaned and sanitized by hand with soap and water or in the dishwasher. Each mask comes with a replaceable fleece filter that is placed between the inner and outer mask.
