Extra Filters for Reusable Face Mask
The material we use to make our filters is MADE THE USA and constructed using a patent-pending Nanofiber technology which is designed to safeguard from airborne particles including bacteria and viruses. It is lightweight and breathable. We pre-cut the material at approximately 6.5" x 4" to fit our masks, and the filters can be easily trimmed to fit other masks.
Filter material is constructed from polypropylene spunbond nonwoven with a Nanofiber fine filtration layer and surface layer of polyester nonwoven.
Filter material has a MERV Rating of 16 and helps filter bacteria along with dust, lint, pollen, mold, pet dander, smoke, fumes, odors, and viruses.
This filter material is NOT washable. Washing filtration material could cause damage and decrease filtration quality. If you choose to reuse the material, we recommend following CDC sanitization guidelines found here:
