Most people think that these pollutants come from outside sources but surprisingly your home can come from a variety of indoor sources such as pets, consumer products and construction materials. If the quality of your indoor air is important to you, look through our list of common places where pollutants become introduced to indoor space.


One of the leading causes of indoor air pollution is gases and particles from combustion. An everyday item such as the household cook stove contributes to killing almost 4 million people worldwide with some of the top pollutants being carbon monoxide (CO) and nitrogen dioxide (NO2). CO is both colorless and odorless so the only way to detect its presence is by installing CO alarms in your home, with a focus on the bedroom and kitchen. Exposure to this harmful pollutant can result in many symptoms, from nausea and headaches to confusion and even unconsciousness; this kills about 500 people annually in the United States.


Rodents and insects are a common source of indoor air pollution and if they are detected homeowners will do the first thing that comes to mind, which is grabbing the pesticide. These pesticides are toxic and contain organic compounds that add to the airborne Volatile Organic Compounds (VOC) levels. Symptoms can vary as it depends on the chemical and dosage; common symptoms include headaches, nausea, long-term brain damage and an increased risk of cancer. Most US homes have used at least one pesticide indoors over the past year, usually insecticides and disinfectants as these chemicals account for up to 80% of the average person’s exposure.

Mold and Mildew

One of the most notorious indoor air polluters are mold, as they thrive in warm and humid areas which are often basements and bathrooms but can spread throughout a home with the right conditions. Symptoms can include nasal congestion, wheezing and even skin irritation; studies have also shown a connection with indoor mold exposure and asthma development in children. Mold is fought by removing moisture from an area, keeping humidity indoors below 60 percent, and using a dehumidifier or fan to dry out air. Mold spots can be removed by scrubbing with soap and water, bleach solution or hydrogen peroxide.
