It’s usually housed in a metal or plastic frame. Once you’ve found it, hold it up to a light to see if it’s dirty. If it looks clean, you can put it back in and close the furnace door.

If it’s dirty, however, you’ll need to replace it. Replacing a furnace filter is easy – just make sure you get the right size for your furnace. Furnace filters come in a variety of sizes, so it’s important to measure the filter opening before you buy a new one.
