Breathing in clean, fresh air is not a luxury; it’s a necessity. It’s even more important when we consider that, on average, Canadians spend 90% of their time indoors. Thus, ensuring the air quality inside our homes is crucial for our health and overall well-being. 

Indoor air quality is no light matter; it plays a significant role in providing a comfortable and safe living environment. Poor air quality inside homes, filled with pollutants and allergens such as dust mites, pet dander, mould, and bacteria, can negatively impact our health, leading to allergies, asthma, and other respiratory issues. Worse still, in extreme cases, certain air pollutants created from combustion processes, such as carbon monoxide, can be fatal.

Climate Experts, renowned for round-the-clock and comprehensive HVAC services, understand the importance of maintaining good indoor air quality. This article will demystify the often-neglected topic of indoor air quality (IAQ), its significance, health implications, and provide practical tips to improve it in our homes, courtesy of Climate Experts, the trusted HVAC professionals serving the Durham region, GTA, and surrounding areas.

By optimizing the quality of the air we and our loved ones breathe inside our homes, we can significantly improve our quality of life.

What Determines Indoor Air Quality?

Understanding the factors contributing to your home’s indoor air quality is the first step in addressing any issues. Here are some of the primary influences on IAQ:

1. Outdoor Environment: The outdoor air coming into your home through openings or your HVAC system can directly impact indoor air quality. Pollutants such as pollen and dust can enter through open windows and doors or your home’s ventilation system.

2. HVAC System Efficiency: A well-maintained and efficient HVAC system is crucial in maintaining indoor air quality by incorporating proper ventilation and filtering pollutants.

3. Humidity Levels: High humidity levels often encourage mould and mildew growth, while low humidity leads to dry air, causing discomfort and potential respiratory issues. Maintaining an ideal humidity range between 40-60% is vital for optimal indoor air quality.

4. Indoor Activities and Materials: Certain household activities and materials contribute to indoor air pollution, such as using cleaning products, paints, and furnishings. Ensuring proper ventilation during these activities can minimize their impact on IAQ.

Practical Tips to Improve Indoor Air Quality

There are several actions you can take within your home to improve indoor air quality:

1. Regularly Change Furnace and Air Conditioner Filters: Replacing your HVAC filters routinely ensures that they can continually effectively remove pollutants and allergens from the air.

2. Properly Maintain HVAC System: By partnering with professionals like Climate Experts for regular HVAC system maintenance, you can ensure your system’s peak performance and maintain ideal airflow, humidity levels, and temperature control.

3. Avoid Tobacco Smoke: A paramount contributor to poor indoor air quality, smoking indoors releases harmful chemicals and can exacerbate respiratory issues for you and your family.

4. Maintain Optimal Humidity Levels: Use a humidifier or a dehumidifier to maintain a balanced humidity level within the recommended range in your home.

5. Increase Ventilation: Open windows and doors whenever possible and use exhaust fans where needed. Proper ventilation helps to reduce indoor pollutants and maintain better air quality.

6. Choose Low VOC (Volatile Organic Compounds) Products: Select low VOC paints, cleaning products, and furnishings whenever possible to decrease the irritants released into your home’s air.
