Before installing your filter, look for arrows on the filter’s package. These arrows show you which direction to install the filter. It must be installed correctly in the direction of the air flow.

After you’ve installed the filter, replace the cover. Remember to reconnect your furnace to the power source. Write the date that you changed the furnace filter on your calendar. Change your furnace filters every two to three months or as needed.
