How Often Should You Change Your Air Filters?

For many homeowners, changing your air filters falls into the “out of sight, out of mind” category. However, making it a point to regularly change out your filters is important for both the air quality of your home and the efficiency of your HVAC system.

So, how often do you need to change your air filters? Unfortunately, there isn’t one fixed answer to this question thanks to several variables in play. Let’s break it down.

If you’re using fiberglass filters

This low-cost option is cheap for a reason — they just don’t last as long. While you’ll save money on the individual filters, you’ll need more of them to maintain air quality and avoid stressing your HVAC system. For most homes, this equates to changing your fiberglass filter every 30 days.

If you’re using pleated air filters

Pleated air filters tend to be made of higher quality materials and will last longer. Depending on the manufacturer and material, you might only have to change your air filters every six months of so — just make sure you check the product for guidelines.

You might need to change more often than recommended if…

Of course, there are other variables at play here to consider. Depending on your circumstances, you may need to change your air filter more frequently than recommended. For instance: 

  • If you have pets who shed
  • If you have allergies or other respiratory conditions
  • If your house is on the larger side and has more air circulating
  • If you live in an area with high air pollution

While it might seem like a tedious chore, maintaining your air filters is the best way to maintain the air quality in your home and ensure your systems are running properly. In fact, regularly changing your air filters can even reduce your energy consumption, contributing to lower utility bills. Do yourself a favor: stock up on a year’s worth of air filters at a time and set a calendar reminder. You’ll be glad you did.
