These filters are designed to fit the Defender and Guardian Face Masks adding additional protection for you and those you love. Experts have stated that adding a filter to a cloth mask adds protection against the aerosol-sized particles that are of concern with the COVID virus.
When using a filter, it is recommended that you replace the filters at least weekly (more often if you are wearing your mask daily).
Filters will have plastic backing for protections during packing and to add ease when inserting into mask pocket. The plastic should be removed once filters in the pocket.
