Impact on Indoor Air Quality
Regularly changing your air filters is crucial for maintaining a healthy indoor environment. Clogged filters can lead to poor indoor air quality, which may cause allergies and respiratory issues. You can learn more about common indoor air pollutants and how to address them.
Energy Efficiency
Dirty air filters force HVAC systems to work harder, increasing energy consumption and utility bills. Keeping filters clean can enhance the system’s efficiency, reducing costs over time.
Extending HVAC System Life
A clean air filter prevents dust and debris from accumulating in the HVAC system, potentially extending its lifespan and avoiding costly repairs. For more tips on maintaining system efficiency, see our moisture effect guide.
Factors Influencing Filter Change Frequency
Type of Filter
The type of filter you use will determine how often it should be changed. Fiberglass filters are typically replaced every 30 days, while pleated filters can last up to 90 days.
Home Environment
Homes with pets, smokers, or allergy sufferers may require more frequent filter changes due to increased levels of dust and allergens.
