13 Common Indoor Air Pollutants and How To Manage Them

June 25, 2026

While many people blame public spaces, high-touch surfaces, and coughing colleagues for their illnesses, a large percentage of our troubles could be occurring from right inside our own homes. The amount of time we spend in our houses and the relative exposure to different types of indoor air pollutants increase the likelihood that negative health effects may arise.


Let’s take a look at some of the causes of indoor air pollution, common pollutants that may be affecting your home, and finally, how to purify your air with the integration of an air filtration plan through a qualified Link ClimateCare service technician.

WHAT ARE THE MAJOR CAUSES OF INDOOR AIR POLLUTION?

To answer this question, we need to look at it through a wide-angle lens. There may be obvious signs of things like mould build-up and rotting materials if your humidity is too high, for example. But other potential hazards, such as radon, an odourless, tasteless gas linked to lung cancer, are largely undetectable and could be the result of the location of your home (not exactly something you can easily change). This suggests that in purifying the home environment, we need to take a global approach that can address multiple problems at once.

INDOOR AIR POLLUTION HEALTH EFFECTS

Depending on the unique challenges found in your home, health effects could range from common colds for a virus picked up from the kitchen counter to diseases and disorders affecting your vital organs from things like radon, asbestos, and VOCs.


Having a home inspection that will thoroughly evaluate your home can go a long way in improving the air quality for yourself and other occupants. In addition, an HVAC professional can help you with air quality solutions to keep the environment free from things you can control, such as smoke, mould, and debris build-up, and maintain overall cleanliness.

HOW TO PURIFY INDOOR AIR

Maintaining your current air filtration system or installing a separate air purifier will go a long way when it comes to managing the pollutants you may be inhaling on a daily basis.
