Quick energy tip: change your furnace filter at least every three months

 

To keep your furnace running most efficiently, make it a habit to change your furnace filter at least once every three months. This is especially important this time of year, when you need your heating system the most.

Use our calendar as a simple reminder - each yellow-highlighted month means it is time to change the filter.

A buildup of pet hair, dust and dirt can restrict airflow and make your heating system work harder; there is even a risk of impurities entering your living space.

Here are three steps from Consumer Reports to easily replace your furnace filter:

Step 1

What kind of filter do you have? 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.

Time out! A filter that has a plastic frame is a reusable model. That means you have clean it only periodically with a vacuum and water, ideally outdoors. Let it dry completely before reinserting.

Step 2

Get the right replacement. Furnace filters are sold at home centers, hardware stores, and online. Disposable ones are typically 1 or 2 inches thick.

Step 3

Install the new filter. 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.
