Replacing your furnace filter may seem like a simple task, but a large number of homeowners don’t realize that there is a right way and a wrong way to install them. We’ve put together some furnace filter tips, including which direction to install them, to help you get your heating system running at its best.
Firstly, it’s important to change your filter regularly, as failing to do so can inhibit your heating system’s performance and efficiency. The best course of action is to replace your furnace filter at least every 90 days, but that number reduces based on how many occupants and pets you have in your home. Just make sure when you replace your filter that you’re installing the new one in the proper direction by following these steps.
Furnace filters aren’t overly expensive, but you want to make sure you’re getting the most out of them and your furnace, and that starts with installing them in the right direction.
- If you don’t already know where your filter is located, take a moment to find it. They are usually installed on the side of your furnace, where the unit meets the ductwork.
- Pull the old filter out and throw it away. We recommended wearing a dust mask when doing this. Make sure you handle the old filter carefully, so you don’t disturb the dust and debris and breathe it in.
- Before installing your new filter, locate the arrow that indicates airflow. The arrow should face towards your furnace and away from the air duct that supplies your unit with air. It’s a good idea to mark the direction of the airflow on your ducts with a sharpie. That way, the next time you replace your furnace filter, you can just point the arrow on the filter in the same direction. We also recommend writing the date of installation on your new filter so you can keep track of when you changed it.
- Your old filter should have the correct measurements on it, so double-check that your new one is the same size.
- Install the new filter by sliding it in with the arrow pointing towards the furnace.
Now that you know how to install your furnace filter in the right direction, it’s a good idea to have one or two extra filters on hand so you can replace them as needed.
