For use with your favorite face masks. Filters out harmful substances, such as droplets, dust, smog, smoke, etc.
Some masks have a pocket or sleeve to insert this filter (our gaiter style and Johnny Was masks, for example DO have these slots). Some masks do not, but you can place the PM2.5 between your mouth and the mask for added filtering and protection.
