Here are kinds of indoor air pollution homeowners must be aware of.


Radon is a radioactive element that works through the earth as a colorless, odorless, invisible, and tasteless gas. It must be ventilated to prevent harmful build-up in the home. You can hire an HVAC expert who will perform a series of tests to determine the levels of radon and where it is coming from to prevent the spread.

Radom forms when uranium in the water breaks down and forms into a harmful gas. Thus, radon will enter the home through even the tiniest cracks in the floors and walls as well as the exterior ventilation, concrete joints, furnaces, and fireplaces.


Volatile organic compounds enter your home through cleaning products, paints, glue, pesticides, hairspray, home printers and even permanent markers. It is important to limit the use of these items to prevent the buildup of VOCs in your home. You can talk with an HVAC tech expert to find out more options on how to filter the pollution out of the home.

Nitrogen Oxide

Nitrogen oxide and dioxide are products that are formed from poor combustion. They will irritate the lungs and mucous membranes in the mouth and eye region. Like the radon pollutant, NO must be ventilated out and removed from the home to avoid serious health risks. You can find NO from sources that include stoves, ovens, poorly installed vent appliances, weldings, kerosene heaters and even tobacco smoke.


Are you using an alternative source for heating such as wood pellets, coal, or a wooden stove? The smoke from these alternatives will get into the air once it is used. The particulates from the smoke can fly into the air in your home and enter the lungs. Using an air purification and filtration will help to reduce the particles that may damage your lungs.

Biological Air Pollutants

One type of biological air pollutants is insect parts. However, the Environmental Protection Agency also mentions viruses, molds, bacteria, pet dander and saliva, hyphae, and mildew spores. The best way to get rid of biological contaminants is through proper air filtration in the HVAC system.

Carbon Monoxide

Carbon Monoxide is a colorless, odorless, heavy, yet invisible gas that has the power to kill and wreak havoc. CO detectors will alert you right away, but even with a flawless furnace, these units have the ability to release CO in the home. If you have detected CO in your home, it is important to contact your HVAC expert to ensure proper sealing.
