What is PM2.5?
PM 2.5 is one of the most dangerous pollutants to human health. It is so small, 1/300th the size of a human hair. PM 2.5 comes from many sources - industrial, vehicular exhaust, trash burning, factories and brick kilns, crop burning, and construction sites, among others.
These invisible particles of tiny pollutants don’t settle; they are suspended in the air and can travel hundreds of miles. PM 2.5 goes deep into our bodies entering the blood stream and lungs.
