Each Reusable Cloth Masks that we sell comes with two (2) of our PM2.5 Activated Charcoal Filters, as we know that cloth masks by themselves offer lower filtration rates. These filters are equipped with 5-layer protection to help filter out almost 100% of particulates in the air. They are made with spun-bound polyester, activated carbon and high-efficiency, melt-blown, non-woven polypropylene.

They can be inserted into the mask via the filter pocket located within the interior layer of the mask.
