Made from meltblown polypropylene filter material, these filters will fit inside both sizes and all styles of our fabric face masks. Included are adhesive aluminum nose bar⁠s⁠—stick these to the filter before adding it to your mask pocket. Once you have the mask on, shape the nose bar to your nose for a better seal. We recommend using a new filter and nose bar each day.

Available in packs of 10, 20, or 40 filters and nose bars. When you order a pack of 40, we can donate a pack of 10 to someone else in need.

Check out our video on Facebook showing you how to insert the filter and attach the nose bar.

This material is certified for level 1 ASTM when used in medical grade masks. Since our masks and most hand-made fabric masks are not medical grade, the filter material will not function at any certifiable level. We make no claims about the effectiveness of this filter material in our masks or your masks. Use at your own risk.

Material is not intended for re-use. It may be a mild irritant to the skin, though we haven't experienced it ourselves. Do not ingest. Avoid contact with eyes. Do not store near sources of ignition.
