How Often to Change a Furnace Filter

Generally, your furnace filter needs to be changed once every 2-3 months, depending on air quality and the size of your home. However, it’s good to get in the habit of checking your filter once a month to make sure it does not need changed sooner. You’ll know that you need to change the filter when it no longer appears translucent upon being held up to the light. If you can’t clearly see light, change your filter!

Since filters are designed to protect your furnace’s motor from dirt, it is important to keep it changed so your furnace works at its best. Your filters keep dirt, dust, and pet hair from getting into your furnace and clogging it up, so keeping a fresh filter in your system is an easy way to avoid the hassle of major breakdowns.

If you are unsure if your furnace filter needs changed, it is always best to consult with an HVAC professional. Schedule furnace maintenance to make sure your filter and all other parts are clean and lubricated properly.

Changing Your Furnace Air Filter

Picking the right furnace filter is easy for most homes—a simple, fiberglass option does the job. However, if someone in your house has allergies or you have more than two furry pets, you may need to consider a disposable paper filter. A disposable paper filter traps smaller particles, helping with dust, pollen, and some air born allergens.

It may be worth it to invest in a high energy particulate air filter if someone in your house has particularly bad environmental allergies or asthma. These filters work to trap microorganisms like mildew, mold, and bacteria.

Changing your filter is a simple task, just requiring a new filter and the ability to turn off your furnace. You should complete the following steps to replace your filter:

  1. Turn off your furnace
  2. Locate and remove the service panel where your filter is located
  3. Slide out the existing filter, found near the intake/outtake blower fan
  4. Insert the new filter (with the arrow pointing toward the motor)
  5. Turn your furnace back on
