Many first-time homeowners may not be aware that if they have a forced-air furnace, it is equipped with a filter that requires replacement every few months. Lucky for you, if you fall into that category, we’re going to walk you through the simple process of taking care of this yourself.
STEP ONE : Identify the Type of Filter
After turning off your furnace, you’ll be able to find the filter inside the furnace or the return air vent. Take note of the arrow on the filter. This tells you the direction of the airflow. The cardboard frame of the filter will also tell you what size it is.
STEP TWO: Purchase Replacement Filter
This step was kind of a given, right? You can find filters at most hardware or home stores, as well as online.
STEP THREE: Install New Filter
The filter will be marked to let you know which side should face the furnace. Simply slide it in, and replace any cover that may go over it. Turn the furnace back on.
