Poor air quality sources

Poor air quality sources

Indoor air pollutants from combustion devices

If your home uses a combustion-based furnace such as natural gas-fired furnace or an oil-burning furnace, these heating systems produce pollution particles from that combustion cycle. Other heating devices such as gas stoves, space heaters, wood-burning stoves and dryers will also produce pollution particles that can affect indoor air quality.

If your home’s HVAC system is installed properly and is up-to-date on maintenance or repairs, these pollution particles should be expelled from the furnace and vented through the exhaust or chimney.

However, if your home’s chimney or exhaust vent are not sealed properly, combustion byproducts such as carbon monoxide and nitrogen dioxide can enter your home’s air and cause symptoms such as dizziness, headaches, irritation of the mucous membranes in the eyes, nose and throat, and, in the case of carbon monoxide, even death.
