Particulate Matter
Particulate Matter (PM) is a mix of tiny solid particles and liquid droplets suspended in the air. Some particles, like dust or soot, are visible, while others are so small they require specialized instruments to detect. PM can come from construction, road dust, smokestacks, fires, and chemical reactions in the atmosphere. It can harm health and the environment, making PM control important for HVAC and indoor air quality.

FAQ
What is PM2.5?
PM2.5 refers to particles 2.5 microns or smaller that can reach deep into the lungs.
Can HVAC filters remove particulate matter?
Yes. Higher-efficiency filters capture more PM, but they must match system capacity.
How can I reduce PM indoors?
Use quality filters, improve ventilation, and reduce indoor sources like smoke or dust.
