How To Replace An Air Filter In A Gas Furnace

Are you a first-time homeowner? Not sure how to replace your air filter—or even what air filter to buy? No worries—we’ve got you covered with our guide on how to replace an air filter in a gas furnace.

How To Replace An Air Filter In A Gas Furnace in 3 Steps

First thing’s first, you need to replace your system’s air filter every 2 to 3 months to keep your furnace running at peak efficiency. Replacing the air filter on a regular schedule also helps keep your indoor air quality pristine (which is ideal if anyone in your home has allergies or asthma!).

Fortunately, replacing a furnace air filter is a simple task. Here’s how to replace an air filter in a gas furnace in three simple steps.

Step One: Determine Your Filter

To determine which filter you have, start by turning off the furnace. Remove the existing furnace filter and examine it thoroughly. Check to see which way the air flow goes, and make note of it—this is how you know which way to install the new furnace filter once it’s purchased!

Then, note the furnace filter size (it should be printed on the cardboard frame around the old furnace filter).

Step Two: Purchase the Correct Replacement

Most local or big box home improvement stores will have furnace filter replacements available for purchase. Remember which furnace filter size you need and pick up at any location. Disposable filters (which is what you’ll need!) are typically 1 to 2 inches thick. Filters that are even thicker can help improve air quality, but may only work with highly-efficient (and new!) furnace units.

Step Three: Install the Filter.

Installing the filter should be as easy as pie. Remember which way the old filter went in and replicate the process. Keep a record of the date installed so you’ll know when it’s time to change the filter again.
