What does PM 2.5 mean?

PM 2.5 refers to particles that are 2.5 microns in diameter. To give you a sense of scale, an average strand of human hair is between 50 to 70 microns in diameter. PM 2.5 filters can filter out particles larger than 2.5 microns in diameter, including most dust, pollen and mold.

Looking for a mask with built-in filters?

Go with N95 masks, filtering facepiece respirators (FFR) that are designed to form a seal around the face for a snug fit. FFR masks meet the United States standard of NIOSH-42CFR84 — basically, they’re super efficient at filtering out airborne particles.
