What is one method to improve indoor air quality affected by combustion appliances?

Regularly scheduled maintenance and inspection of combustion appliances is an effective method to improve indoor air quality. This practice ensures that these appliances are functioning correctly, preventing the release of harmful byproducts such as carbon monoxide or unburned fuel into the home environment. A well-maintained appliance operates more efficiently, which minimizes emissions and enhances overall air quality.

This method also includes checking for proper ventilation, ensuring exhaust systems are clear, and that safety mechanisms are in place. By investing in regular maintenance, homeowners can identify potential problems before they escalate, thereby safeguarding the health of occupants and improving the indoor air quality significantly.

While other options can contribute to air quality, such as using electric appliances or installing air purifiers, these do not address the root causes and sources of indoor pollution from combustion appliances like regular maintenance and inspection do.
