Our masks are made from double-layered, 100% Cotton for breathability and protection with tie straps for easy adjustment. An interior pocket is sewn inside to insert filters to create another barrier for added protection. These masks are non-medical grade.
Filters: You can use any HEPA grade filters for easy DIY inserts. These include air purifier filters, vacuum filters, and air conditioning filters. Please note that you should not use filters with fiberglass materials. If you do not have any of these on hand, you can also use a coffee filter or paper towel.
