Caring for your furnace can go a long way in the months in between furnace service appointments. One of the simplest, and crucial, ways to maintain your furnace is by replacing your furnace filter. Having a dirty air filter may contribute to a host of negative issues for your heating and cooling system, its efficiency, and ultimately, how much your energy expenses are every month.
So what goes in to consideration when you should replace your furnace filter?
- Type of filter: the two most common filter sizes are 1 inch and 3 inch filters. 1 inch filters usually need to be changed every month and 3 inch filters should be replaced every three months, based on the recommendations of the filter maker.
- Home habits: if you have pets in your home, it could make sense to switch out your filter more often due to pet dander. If a family member has allergies or asthma, consider switching out your home’s air filter more regularly to help with their symptoms.
Now you’re likely wondering how to replace your furnace filter. Obviously this will vary depending on what furnace you have, but typically:

- Open or take off the air filter panel around the bottom of your furnace to uncover an open compartment.
- On the top of that open compartment is where your furnace filter is resting on two metal lips.
- There will be a little space to move your filter back and forth that allows you to pull down one end of the filter and remove it from the compartment.
- When adding the new filter, look at the perimeter of the filter for an arrow that shows you the air flow direction, to ensure you’re installing the filter in the right direction. In most cases, the arrow should point towards the main part (or top) of the furnace.
