Disposable filters made from 2.5oz 80% polyester / 20% nylon non-woven textile.
We recommend changing the filter every time you wash your mask.
NOTE: Face mask usage is just one component of a holistic risk-management strategy, along with social distancing, washing your hands often, and not touching your face. This mask is not FDA approved, has not been tested for efficacy, and is not officially approved for medical use.
NOTE: Removable filter layer provides an additional barrier against tiny droplets, but mask may be used without a filter as well (the two layers of cotton fabric provide basic protection). Please see our FAQ page for other DIY filter options.
Standard (Adult) size: 6" x 3"
