These double-layer hydro knit filters block more tiny 0.3 micron particles than cotton alone.* They fit inside all COCO KNOWS masks to add an extra two layers of protection. They technically may be hand washed in hot, soapy water and air-dried, but this may reduce their effectiveness. Therefore, we recommend discarding the filter each time you wash your mask.

Masks in photos are to show (1) the size of the filters relative to the mask as well as the filter pocket on the inside of each mask (2).

Set of 10 single-use filters.

MADE IN OREGON

*These are non-medical filters for personal use. For safety reasons, all filters are final sale.
