How To Change a Furnace Filter

Your furnace filter removes small particles from the air flowing through a forced-air furnace and through your house. A dirty filter makes your furnace work harder to move that air. The additional strain drives up energy consumption and could lead to equipment failure. Changing a furnace filter is easy to do, and homeowners should plan on doing it two or three times during the heating season.

How to Find the Furnace Filter

A furnace filter fits into a compartment between a furnace’s incoming air and the combustion chamber. Labels on some furnaces indicate where the filter is located. In their absence, look for a panel covering a large slot or the blower motor. You might need a screwdriver to open this panel.

Determine Filter Size

Once you physically see your filter, you can simply lift or pull it out of the furnace. The old filter will have its dimensions printed on it. Buy new filters of the exact same https://lh3.googleusercontent.com/4nlKvMiW04FOrPX4mWu0fa2kIa4QgJ6JVKUpQGTE5yvCKGLBtj0JZE-OUV4ELENfxbKeuaXYMIZohkEANw=s239-cdimensions. This is crucial because a filter that falls out or allows air through gaps around it defeats the purpose of having one. If your furnace is missing a filter entirely, then measure the height, width and depth of the compartment where it goes.
