For your safety, you should always turn off the furnace before beginning any kind of maintenance work. Your furnace should have an on-off switch located on the wall next to the unit. Make sure the switch is in the “off” position until you’re done replacing the filter.
Once the furnace is safely off, locate the filter. Each furnace is designed differently, so not all filters are located in the same place. If you’re having trouble finding the filter, you can simply check the owner’s manual or look up the model number on the internet. Most filters are located in the ductwork above the furnace or behind the furnace cover in the blower compartment.
Remove the old air filter by gripping the cardboard frame and gently pulling it out. Most furnace filters are disposable, so you can toss it right into the trash. However, some filters are reusable, and you simply need to wash it off before replacing it.
Time for the new filter! Filters are designed with a right-side-up designed by an arrow. Make sure the arrow is aligned correctly, then slide the new filter into the slot.
Last step! Once the new filter is securely inside the furnace, switch the furnace back into the “on” position.
