“Smoke from residential fireplaces is a significant source of PM2.5 (particulate matter) during the winter months in the South Coast Air Basin,” Wayne Nastri, AQMD executive officer, said in a statement. “Residents can do their part to improve air quality by spreading awareness and choosing not to burn wood when No-Burn Days are announced.”

On a No-Burn Day, wood-burning will be banned for 24 hours in residential fireplaces, stoves or outdoor fire pits.
