Learning some basic information about how HVAC filters function and their importance can equip you to better care for your system. Read on to discover how using HVAC filters properly can benefit your system and keep it running in peak condition.

Some Filters Are Different From Others

Most HVAC filters are made from fiberglass. HVAC filters are rated using the Minimum Efficiency Reporting Values scale, which runs from one to 13. According to the Environmental Protection Agency, for a filter to receive a rating of 13 on this scale, it must remove 50% of the tiniest particles during testing. Your HVAC contractor can make recommendations for the best filter for your system.

Filters Improve Air Quality and Protect Your System

Your HVAC system not only heats and cools your home but also controls much of the air quality in your space. Filters help remove impurities, allergens, and other particulates from the air to improve indoor air quality. They work by keeping dust and debris out of your HVAC system, creating a more pleasant environment and allowing you to breathe with ease.

Your Filters Need to Be Changed Regularly

You must change the filters in your HVAC often to ensure free airflow to your system. Dirty filters make your system work harder and less efficiently. Routine filter changes can extend the life of your system. An HVAC contractor can tell you how often you should change your filter based on your equipment, family size, and household composition. A good rule of thumb is to change your filters at least once a month. If you live in a large household with pets, you may have to change your filters more frequently.

The best way to judge when you should change your HVAC filters is to monitor them closely to determine when they start to get dirty. Filters should never be allowed to accumulate large amounts of animal hair, dust, or debris. They should be swapped out as soon as they start to get dirty. It never hurts to change filters more often than you think you need to.
