Regularly changing your residential HVAC system’s filter is crucial for several reasons. It traps air contaminants to prevent them from recirculating throughout the home, promoting optimal indoor air quality. In doing so, it also blocks these particles from entering the HVAC system and affecting its performance. Generally, you should replace your filter every 90 days, but this can change based on a few factors that are discussed below.

A Guide to Residential HVAC Filter Replacement

What Are the Benefits of Replacing Your Filter?

Changing your filter promotes cleaner indoor air, which smells fresher and is less likely to aggravate asthma or allergies. It also helps maximize the life span of your HVAC system, improve its performance, and save on heating and cooling costs. The U.S. Department of Energy states that replacing a clogged air filter with a new one can reduce energy consumption by 5% to 15%.

Which Factors Determine Your Replacement Schedule?

If you or a family member has allergies or asthma, you should replace your air filter more frequently than others. Otherwise, contaminants like mold and dust recirculate throughout the home, potentially exacerbating symptoms. In these circumstances, you should change your air filter once per month.

residential HVACHomes with large families should also consider monthly replacements, as having more family members leads to more dust and debris. Families with small children should also replace their filter every one to two months to promote optimal air quality for little ones, as should anyone with pets.

Are There Alternatives to Frequent Replacements?

The quality of the residential HVAC filter you purchase may also play a role in how often you need replacement. Cheaper filters may not hold up as well as higher-quality models, and you may need to change them more frequently. If you purchase a higher-quality filter designed for allergy sufferers or pet owners, for instance, you may be able to stretch its life span longer than standard alternatives.
