These replaceable filters are designed to provide extra protection to face masks. Our much loved Rozcraft masks can be ordered with a pocket to allow you to place the filter inside the cotton layers or you can simply sit the filter on the inside of your mask and have it against your face. If you'd like a pocket, scroll to the bottom of all the designs on the masks page and add that option to your cart along with your chosen mask designs. See pics here of the pocket and non-pocket options.
Made from from activated carbon and non-woven melt-blown filter cloth. The filter consists of 5 layers designed to keep out very fine particles (PM2.5) and a range of airborne contaminants
Filters should be replaced after every 16-24 hours of total use (this equates to a week or 2 of casual use). Remove the filter from your mask before washing the mask.
Filter Size 12cm x 8cm, fit both adult and child's masks. Sold in a pack of 5.
