Filters - Microfiber or Flannel
Description: These filters are created for our masks specifically. You can order flannel or microfiber; the filters have two layers of high quality cotton sandwiching the selected material. The non-organic materials are able to collect more of the particles due to static charge.
Size: 5"x4" They fit the pockets created in our plain masks as well as being generally useful to place inside any masks for additional protection.
These filters are machine washable and resusable.
