What is PM2.5? Particulate matter (PM) is a term used to describe the mixture of solid particles and liquid droplets in the air. It can be either human-made 


Fine particulate matter (PM 2.5) is an air pollutant that is a concern for people's health when levels in air are high. PM 2.5 are tiny particles in the air that reduce visibility and cause the air to appear hazy when levels are elevated. Outdoor PM 2.5 levels are most likely to be elevated on days with little or no wind or air mixing.
