Invisible to the naked eye, the air we breathe in contains many tiny particles of chemicals, soil, smoke, infectious diseases, dust or allergens in the form of liquids, gases, or solids. The release of many of these particles are largely due to the burning of greenhouse gases. These minuscule airborne hazards are referred to as particulate matter, or PM.

Wearing a fitted mask with a PM2.5 filter can substantially reduce the ingestion of airborne particulates, including infectious pollutants and wildfire smoke pollution. 

The PM2.5 filter are made of the same advanced materials used for respirators like the N95 and KN95, in addition to activated carbon fabric. It provides both mechanical and electrostatic barriers making it capable of blocking even the very smallest nanoparticles.
