Your furnace filter can help clear the air in your home but also if replaced every few months it can keep your furnace running at peak efficiency all year round—and help prevent pollutants from entering your living space.
Fortunately for all of us, replacing a furnace filter is a pretty simple task, once you know what you’re doing. There are ways of doing it wrongly, for example by buying the wrong furnace filter or putting it in backwards, which could block the flow of air instead of cleaning it. Here’s how to do the job properly in three simple steps.
1.What kind of filter do you have?
The first step to an effectively filtered heating, ventilation and air conditioning system is the correct insertion of a furnace filter. If the filter is inserted the wrong way, it will not filter as effectively, airflow will be impeded and the strain on the furnace motor will increase. The first step in air quality, efficiency and proper furnace operation is the correct installation of the furnace air filter.
Start by turning off the furnace. Remove the existing furnace filter, which will be located inside the furnace or inside the return air vent. Look for an arrow on the filter indicating airflow direction. Using a permanent marker, draw the airflow direction on the outside of the furnace, so you’ll always know the right way to install the filter. Then note the furnace filter size, which will be printed on the cardboard frame.
If your filter has a plastic frame, that means it is a reusable model. You have to clean it periodically with a vacuum and water. Let it dry thoroughly before reinserting.
2. Get the right replacement.
Furnace filters are sold at home centers, hardware stores, and online. Using the notes from your previous one, go ahead and make the purchase.
3. Install the new filter and take note.
Look for the markings that tell you which side of the filter should face the furnace. Then slide the filter back into place and replace any cover that goes over it. Keep a record of the date so that you’ll know when it’s time to change the furnace filter again.
