Filters for reusable cloth face masks. Comes with 10 double layered filters. Does not include the mask. This provides you some added protection that you can put into our cloth face masks. They are about 5.5”x5.5” oval sort of shape so that they fill up the majority of our cloth face masks when inserted into the filter pocket. They can be cut down easily to fit other reusable face masks These are double layered made from Halyard H600 Sterilization Wrap. Non woven Polypropylene. We chose this for our filter material based on research done by  University of Florida Health. See their link below for more information.
