Designed for use with our Face Masks. This replacement pack of HEPA filters includes 12 triboelectric filter media inserts. The filter is made of ultra-lightweight, non-woven fabric, adding an extra layer of protection when wearing a face mask. Your filter could be a solid finish or a patterned finish depending on what is available, but the material's effectiveness does not differ. The filters are non-washable.
