Extra Mask Filters
5 pack of Mask filters for your mask.
A set of five pieces of disposable nano-fiber filters designed for our protective face masks with an inner pocket. Use the filter for about 8 hours, then the filter loses its effectiveness and it must be discarded and the face mask properly sterilized. The disposable filter offers excellent breathability while maintaining filtration efficiency. The filters are made from a three-layer material with a nanomembrane.
