AC and Furnace Filters Explained
It’s crucial for heating and air conditioning systems to be well-maintained to keep them working efficiently, with fewer problems, and to improve their longevity. However, in addition to professional maintenance, one maintenance task that needs to be done more often is air filter replacement. This blog post will discuss air filters, including what they do, when they should be replaced, and the advantages of regularly replacing them when needed.
What Do Air Filters Do?
Air filters help protect indoor air quality and HVAC equipment, trapping airborne contaminants and particles to stop them from circulating in the air and affecting residents’ health, and preventing them from getting into the heating or cooling system and causing problems.
As air flows through the system, AC and furnace filters capture particles while letting air through. However, filters will eventually become clogged and dirty with these contaminants, which reduces airflow and causes problems for the heating or AC system. Once clogged, filters will lose the ability to capture more particles as well, which can lead to poor air quality. So, air filters must be routinely replaced so they can continue working as intended.
Not all air filters can capture the same size of contaminants. The higher a filter’s MERV (minimum efficiency reporting value) rating, the more effective it is at capturing smaller particles than filters with a lower MERV rating. So, understanding MERV rating helps people select the appropriate filters for their household’s needs without restricting proper airflow through the system.
How Often Should Filters Be Replaced?
Most standard air filters should be replaced every one to three months, though this timeline can vary based on several factors, including filter type and size. Environmental conditions can also impact replacement frequency because homes with pets, smokers, or in dusty areas can have their filters become dirty sooner, requiring more filter changes.
When people in the home have allergies or asthma, more frequent filter replacement can also offer substantial relief because clean filters are more effective at capturing airborne allergens and contaminants and improving respiratory health. A reliable indicator that filter replacement is needed is checking the air filter's appearance monthly. If it looks dirty and dusty or homeowners can't see light through it when held up, it's time for a change.
Benefits of Timely Air Filter Replacement
Regular air filter replacement delivers far more benefits than some homeowners may realize. It helps maintain good indoor air quality by preventing dust, allergens, and pollutants from circulating throughout the home. Capturing allergens and irritants can reduce symptoms of allergies and respiratory issues and improve the health of sensitive household members.
Beyond cleaner air, timely AC and furnace filter replacements can extend the lifespan of heating and air conditioning equipment and keep them more energy efficient. When filters become clogged, the system becomes inefficient and must work harder. This raises utility bills and creates unnecessary strain on vital components, which can lead to problems, comfort issues, and the need for early replacement. So, for better indoor air quality, energy efficiency, lower utility costs, a lower risk of problems and repairs, more consistent temperatures, and a longer lifespan for the heater or air conditioner, homeowners should be sure to change air filters regularly.
