All About Air Filters
While households might rely heavily on their heaters and air conditioners to keep them comfortable, homeowners might overlook an essential task—changing the air filters on time. Replacing AC filters is essential in keeping air conditioning systems running correctly and efficiently. In this post, learn what air filters do, how often they should be replaced, and the benefits of replacing them on time.
What Do Air Filters Do?
Air filters are essential components to keep heating, ventilation, and air conditioning (HVAC) systems working correctly, maintaining good indoor air quality and system efficiency. AC and furnace filters capture particles such as dust, pollen, pet dander, viruses, bacteria, and other allergens and contaminants from the indoor air.
By removing these pollutants, air filters help improve indoor air quality, reduce allergy and asthma symptoms, and prevent the buildup of dust and debris in the HVAC system, which can cause inefficiency, cause them to break down unexpectedly, and shorten their lifespan. However, they will become dirty and clogged over time because they capture pollutants, requiring routine air filter replacement.
How Often Do Filters Need to Be Replaced?
To keep households healthy and HVAC systems operating correctly, homeowners must regularly replace their furnace filters and AC filters. How often the filters should be replaced depends on their size and type, but it’s typically recommended that they be changed every three months. However, this timeline may need to be sped up if certain circumstances occur in a household.
If families have pets, if they have recently done home construction, or if members of the household suffer from allergies or asthma, they may need to change the air filters more often. A good way to tell if filters need to be replaced is to check them monthly and replace them when they look dusty or dirty.
What Are the Benefits of Replacing Them on Time?

- Better indoor air quality: Clean filters can more effectively capture dust, allergens, and other contaminants from a home’s air, improving the home’s air quality and reducing allergy symptoms and respiratory problems among household members.
- A more energy-efficient HVAC system: Clean air filters allow for better airflow, leading to air conditioners and heaters operating more efficiently.
- Lower energy costs: When the HVAC system operates more efficiently, it doesn’t have to work as hard, which leads to lower utility bills.
- Longer-lasting HVAC system: When dust and pollutants build up on and clog filters, it can cause heaters and air conditioners to break down, leading to a higher chance of needing repairs and shortening their lifespan.
- More even heating and cooling: Furnace filter and AC filter replacements, when needed, improve the airflow and allow for better temperature control and more even heating and cooling for maximum comfort.
