Taking care of your furnace can go a long way in the months in between furnace service appointments. One of the simplest, and critical, ways to care for your furnace is in replacing your furnace filter. Having a dirty air filter can contribute to a host of adverse problems for your heating and cooling system, its efficiency, and ultimately, how much you’re spending on your energy bills each month.
So what goes in to deciding when you should switch out 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 switched out every month and 3 inch filters ought to be swapped out every three months, dependent on the recommendations of the filter maker.
- Home habits: if you have pets in your home, it might make sense to change your filter more often as a result of pet dander. If you have someone in the house that suffers from allergies or asthma, consider replacing your home’s air filter more frequently to help ease their symptoms.
Now you’re likely wondering how to change your furnace filter. Obviously this will change depending on what furnace you have, but usually:

- Open or remove the air filter panel close to 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 supports.
- 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 pull it out of the compartment.
- When adding the new filter, look at the perimeter of the filter for an arrow that specifies the air flow direction, to ensure you’re installing the filter in the correct direction. In the majority of cases, the arrow should point towards the main part (or top) of the furnace.
