Proper way to install an air filter

Still confused? A simpler way to figure this out is to always make the arrows face the ceiling or wall. If your filter is on the wall, the arrow should face the wall. If your filter is on the ceiling, the arrow should face the ceiling. Still not finding the arrow? The side with the wire frame should be facing outward and the side without it will be inside closer to the unit. In most furnaces, the filter will be adjacent to the furnace and is inserted where the ductwork meets the furnace.

Determine where on the furnace you can find the filter air box. Stand in front of the furnace and look for the ducts. Pull the old filter out and discard it. On the new filter, find the arrow indicating the proper airflow direction. The arrow must face toward the furnace and away from the return duct that pulls the air in need of heating or cooling.

Slide the new filter in with the arrow pointing toward the furnace. Replacing your air filter is not difficult. Remember that air flows from your ducts, through the filter, and into the furnace. Changing furnace filters regularly provides great impacts on home comfort and indoor air quality, as well as energy efficiency, and the longevity of your system. Considering how important a furnace filter direction, it is a good idea to ask your HVAC technician to explain the best filter, when to change and how to install.
