How Often Should You Change Your Air Filters?

When was the last time you changed your air filter? If you’re scratching your head trying to remember, you’re not alone. Many homeowners aren’t sure how often they should swap out their filters, and that’s okay! We’re here to clear the air (pun intended) and make it simple.

Why Are Air Filters So Important?

Air filters do more than just keep your air clean. They protect your HVAC system by trapping dust, pet hair, pollen, and other particles. A dirty filter not only impacts your indoor air quality but also makes your system work harder, which can lead to higher energy bills and costly repairs.

So, How Often Should You Change Them?

This is the question everyone wants the answer to, right? After all, it’s why you stumbled upon this blog in the first place. The answer depends on a few factors, like the type of filter you use and your living situation. Here’s a quick guide to help you out:

• Every 30-60 Days: If you’re using a basic fiberglass filter, it’s a good idea to replace it every month or two. These filters are inexpensive but don’t last long.
• Every 90 Days: Pleated filters, which are more durable and efficient, can usually last about three months.

• Every 20-45 Days: Got pets? Their fur and dander can clog filters quickly, so consider replacing them more often—especially if you have multiple furry friends.
• Every 60 Days: If you or someone in your home has allergies or asthma, a cleaner filter will make a big difference in air quality.
• Every 6-12 Months: Some high-end, reusable filters only need to be cleaned or replaced once or twice a year. Just make sure to follow the manufacturer’s guidelines.

Factors That Affect Filter Life

• Household Size: The more people (and pets) in your home, the faster your filters will fill up.
• Location: Living in a dusty area or near construction? Your filters might need more frequent attention.
• HVAC Usage: If you run your HVAC system year-round, you’ll need to change the filters more often.

A Simple Way to Remember

If remembering to change your air filter feels like just one more thing on your endless to-do list, try setting a recurring reminder on your phone. Some people even change their filters every time they get their utility bill—two birds, one stone!
