How Often Should I Change My HVAC Air Filters?
Changing your HVAC air filter might seem like a small task, but it plays a big role in your system’s performance, energy efficiency, and indoor air quality. At Integrity Air Solutions, we get this question often—and the truth is, the answer depends on a few key factors.
General Rule of Thumb
For most homes, changing the air filter every 1 to 3 months is ideal. However, certain factors may require more frequent replacements to keep your HVAC system running at its best.
What Affects Filter Replacement Frequency?
Type of Filter:
Basic fiberglass filters usually need changing every 30 days, while higher-quality pleated filters may last up to 90 days.
Pets in the Home:
If you have pets, their fur and dander can clog filters faster. We recommend checking and possibly changing the filter every 1 to 2 months in homes with pets.
Allergies or Asthma:
If anyone in your home suffers from allergies or respiratory issues, clean air is critical. Replace your filter every month to maintain healthier air.
Home Size and HVAC Use:
Larger homes or systems that run constantly (especially in extreme weather) may require more frequent filter changes to maintain efficiency and airflow.
Indoor Air Quality:
If you live in an area with high dust, smoke, or pollen levels, or if you frequently open windows, you may need to replace filters more often.
