This filter is a PM2.5 (2.5 micron, particulate matter) 5-Layer, Activated Carbon Filter, which is used (inside a mask) to protect your mouth and face from dust, haze, allergies, smoke, pollution, ash, pollen, hazardous chemicals and heavy metal particles.  Using one of these filters in a suitable mask properly gives you an added layer of protection from the air and airborne particulates in your environment (at or above 2.5 microns), and protects others in your vicinity from your saliva droplets.  not reccomended for toddlers
