IMPORTANT NOTE: Before choosing air filters to use for your face masks, be sure to double check the materials used in the brand of air filter. Filtrete air filters–the kind we’re using–are common and don’t use fiberglass. But it’s possible some filters, especially ones not made in the US, may use fiberglass. Be sure you don’t use those.
It’s easy to make face masks out of air filters, and these face masks are much more effective than ones made out of cotton or other fabrics. We hope they’ll help you stay safe in the COVID-19 pandemic (and whenever else you need a good face mask!)
