What is airborne particle pollution in my home?

Airborne particles can come from sources such as cigarette smoke, cooking (especially frying), malfunctioning furnaces, wood burning appliances and mold growth.  Other sources of airborne particle pollution include burning candles, home renovations and ongoing activities that cause increase in dust and airborne particulate matter in the home. Particulate matter can also be formed from substances such as carbon (soot), liquid or solid particles in aerosols, fungal spores, pollen or toxins present in bacteria.
