description
A single-use, universal PM2.5 Activated Carbon Filter accompanied by an inspection certificate. Filters can reduce the amount of fine particulates inhaled outside and indoors. Common particulate sources are dirt & dust, pollen, smoke, or smog. Comes in packs of 10. 5-layer filters that fit in the filter pocket of our Cotton Casual Face Mask. Filters are single-use and should be removed and disposed of before washing face mask.
PM stands for particulate matter and the 2.5 refers to the size of the particulate in micrometers that can pass through the filter. (For reference, 2.5 micrometers is roughly 30 times smaller than a human hair.)
