The Air Pollutants That Could Be In Your Home

Posted in Air Quality, on February 08, 2021

In your community, homeowners are booking air quality testing in Toronto and discovering that hidden pollutants, allergens, and chemicals linger in even the cleanest and newest of buildings. Paying close attention to indoor air quality testing results has a big effect on everything from restorative sleep to healthier skin — and good indoor air quality isn’t hard to achieve. 

Some of the most common air pollutants that we find in Toronto and GTA area homes include: 


Commonly used until the 1980s in everything from insulation to flooring, asbestos was once called the “miracle mineral” for its seemingly endless uses in construction and homebuilding. Asbestos was eventually banned after research uncovered the devastating effects of exposure and increased risk for rare cancers, but it still lingers in many homes.  

Carbon Monoxide

Carbon monoxide can build up indoors from leaking appliances or the improper use of fuel-burning equipment, like barbecues. Carbon monoxide prevents the body from using oxygen efficiently, often causing victims to lose consciousness, and is especially dangerous because it’s invisible and has no taste or smell. 


Peeling or chipped paint isn’t just unsightly — it’s dangerous too.  Many household paints are used to contain the toxic heavy metal lead, which causes a range of cognitive and physical defects in  fetuses, babies, and children. Before removing any old paint or demolition, indoor air quality testing can help identify the presence of lead and ensure your renovations are safe. 


This chemical is a common preservative found in everything from composite wood to glue to dishwashing soap. It’s also sometimes created when two chemicals react, causing skin, nose, and airway irritation. Formaldehyde has been linked to several different types of cancer as well as asthma and respiratory issues. 

Nitrogen Dioxide

Nitrogen dioxide is a by-product of fuel burning. Breathing in air that has a high concentration of this chemical can cause severe respiratory irritation, such as wheezing and coughing. While it’s more commonly identified as a cause of outdoor smog, nitrogen dioxide is commonly picked up during air quality testing for residents living near highways, factories, or industrial areas.
