How Often Should I Change HVAC Air Filters?

One of the simplest ways to maintain good indoor air quality and protect your HVAC system is by regularly changing your air filters. A clogged filter restricts airflow, forcing your system to work harder and leading to higher energy bills and unnecessary wear and tear. But how often should you replace your filter?

For standard 1-inch filters, we recommend replacing them every one to three months depending on factors like pet ownership, allergies, and indoor air pollution levels. If you have a high-efficiency pleated filter, you may be able to wait six to twelve months between changes, but regular inspections are still essential. Homes with pets, smokers, or allergy sufferers should change filters more frequently to maintain clean air and system efficiency.

The Whole-House Filter Difference

Basic HVAC filters—also known as blower filters—are designed to protect your system from dust buildup, not to remove harmful contaminants from the air. These filters have limited efficiency when it comes to trapping allergens, bacteria, and airborne pollutants.

That’s where whole-house filtration systems come in. A professionally installed whole-home air filter integrates directly into your HVAC system, capturing particles like dust, pollen, pet dander, and even some airborne viruses before they circulate through your home. Unlike small, portable air purifiers, whole-house filters treat all the air moving through your system, providing comprehensive coverage.
