Indoor Air Pollution – How It Affects Your Health

According to the Clean Air Day Campaign, indoor air pollution can be much worse than outdoors.

What is indoor air pollution?

Indoor air pollution is dust, dirt, or gasses in the air inside your home or any building that harms us if we breathe it in. Certain people may be disproportionately impacted by indoor asthma triggers, secondhand smoke, mold, radon, and other indoor pollutants.

What causes indoor air pollution?

  • Gas cookers
  • Damp and mold
  • Cleaning products
  • Cigarette smoke
  • Carbon monoxide leaks

Your HVAC system plays a crucial role in maintaining indoor air quality. Here’s how it can help:


  • HVAC systems are equipped with air filters that capture dust, pollen, pet dander, and other airborne particles.
  • Check your filters on the first of every month and replace them if they are noticeably dirty.


  • Proper ventilation is essential for circulating fresh outdoor air into the indoor space and removing stale air.
  • HVAC systems with ventilation features help dilute indoor air pollutants and prevent the buildup of harmful substances.

Humidity Control

  • Excessive humidity can promote the growth of mold and mildew, while low humidity can lead to dry skin and respiratory issues. HVAC systems can regulate indoor humidity levels, creating a comfortable and healthy environment.

Regular maintenance of your HVAC system, including filter replacement and professional cleaning, is essential to ensure optimal performance and indoor air quality.
