Maintaining your furnace can go a long way in the months in between furnace service appointments. One of the easiest, and essential, ways to care for your furnace lies in replacing your furnace filter. Having a clogged air filter may contribute to a variety of negative concerns for your heating and cooling system, its efficiency, and ultimately, how much your energy costs are each 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 typically need to be switched out every month and 3 inch filters should be changed every three months, dependent on the recommendations of the filter maker.
- Home habits: if you have pets in your home, it could make sense to replace your filter more often as a result of pet dander. If a family member deals with allergies or asthma, think about replacing your home’s air filter more regularly to help potentially decrease their symptoms.
Now you’re probably wondering how to replace your furnace filter. More than likely, this will differ depending on what furnace you have, but typically:

- Open or pull off the air filter panel near the bottom of your furnace to reveal an open compartment.
- On the top of that open compartment is where you’ll see your furnace filter resting on two metal brackets.
- 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 take it out of the compartment.
- When adding the new filter, inspect 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 nearly all cases, the arrow should point at the main part (or top) of the furnace.
