Understanding the Factors Affecting Indoor Air Quality

Indoor air quality (IAQ) is influenced by various factors contributing to the presence of pollutants and allergens in the home. These factors include inadequate ventilation, humidity levels, combustion sources such as stoves and fireplaces, building materials, cleaning products, and outdoor pollutants entering through windows and doors. Being aware of these factors can help you identify and address potential issues to improve your indoor air quality.

Common Indoor Air Pollutants and How to Reduce Them

There are numerous common indoor air pollutants found in our homes, ranging from biological contaminants to chemical contaminants. Some of the most prevalent include the following:

1. Dust mites and pet dander: These allergens can cause allergy and asthma symptoms. Regular cleaning, including vacuuming and dusting, can help reduce their presence.

2. Mold and mildew: These biological contaminants thrive in damp conditions, potentially causing respiratory issues. Address the source of moisture and keep humidity levels below 60% to prevent the growth of mould and mildew.

3. Radon: A radioactive gas emitted naturally from soil and rock, radon can accumulate in homes, posing health risks. Test your home for radon and install an appropriate mitigation system if required.

4. Volatile organic compounds (VOCs): Found in many household products, VOCs can cause various health issues, including headaches and respiratory problems. Opt for low-VOC or VOC-free products and ensure proper ventilation when using these products.

5. Carbon monoxide: Toxic and odourless carbon monoxide (CO) is a byproduct of incomplete fuel combustion in appliances. Install CO detectors and have your heating system inspected annually to prevent CO buildup.

Measuring and Monitoring Indoor Air Quality: Tools and Techniques

Monitoring your indoor air quality is essential for maintaining a healthy home. Various tools and techniques can help you assess and track IAQ, including the following:

1. Air quality monitors: These devices measure temperature, humidity, VOCs, particulate matter, and other pollutants, providing you with real-time data on your indoor air quality.

2. Carbon monoxide detectors: Installing CO detectors will alert you to dangerous CO levels in your home, allowing you to take immediate action.

3. Humidity meters (hygrometers): Monitoring indoor humidity levels can help you maintain a healthy home environment, as high humidity promotes mould growth, while low humidity can cause respiratory issues.

4. Radon test kits: Available in both short-term and long-term testing options, these kits help you identify potentially dangerous radon levels in your home.

5. Professional indoor air quality assessment: Hiring a professional to assess your home’s indoor air quality can provide insights into specific issues and recommendations on how to address them.

The Role of HVAC Systems in Maintaining Indoor Air Quality

Your home’s HVAC system plays a vital role in maintaining healthy indoor air quality by circulating air, filtering pollutants, and regulating humidity levels. Properly maintaining your HVAC system can significantly improve IAQ, while poor maintenance can compromise air quality. Some best practices for maintaining your HVAC system to ensure optimal indoor air quality include the following:

1. Regularly inspect and replace air filters: Clogged or dirty air filters can cause pollutants to circulate in your home. Replace filters according to manufacturer recommendations.

2. Schedule routine maintenance: Regular professional maintenance of your HVAC system will ensure optimal performance and prevent issues related to poor indoor air quality.

3. Address issues promptly: If you observe any unusual smells, noises, or performance issues with your HVAC system, seek professional assistance to address the problem and avoid exacerbating IAQ concerns.

4. Clean and maintain air ducts: Dirty ductwork can lead to poor air quality. Have your ducts professionally cleaned and inspected at least once every three years to prevent the buildup of dust, debris, and allergens.


Indoor air quality plays a pivotal role in our health and well-being, making it vital for homeowners to understand the factors affecting it, as well as ways to improve it. By reducing indoor air pollutants, monitoring IAQ, and properly maintaining your HVAC system, you can create a healthier, more comfortable home for you and your family.
