What is PM0.3 Pollution and Why Is It Important?

May 06, 2019PM0.3 is particulate matter – solid or liquid particles in the air – 0.3 microns in diameter. 0.3 microns is a critical size because it's the hardest particle size to capture. Brownian motion works its magic for particles smaller than 0.3 microns, and filtering works for particles bigger than 0.3 microns. HEPA and masks filters are still
