How to Properly Insert a New HVAC Filter

It is extremely important to regularly monitor and change them according to the manufacturer’s directions. When air filters become clogged with dust, dirt and debris, they are no longer able to their job of improving the indoor air you breathe. Dirty air filters also force your HVAC system to work harder than necessary, decreasing equipment’s life and increasing your energy bills. In fact, Energy.gov reports that replacing a dirty, clogged air filter with a clean one can lower your central air conditioner or furnace energy consumption between 5 and 15 percent! So, you go to change your air filter, but you end up a little confused. Not really paying attention to small details, you take the old filter out, grab the new filter, but which way does it go in? There’s an arrow on the filter with the words “Air Flow”, but what does that mean? How do you know which way the air flow is going? Here’s what you need to know to properly insert a new filter into your HVAC system.

The Arrow and Air Flow Direction

To properly insert a new filter, look for the arrow! The arrow on your filter should always face the unit and away from the return air duct that carries the air that will be heated or cooled. HVAC systems push the cool or warm air out and pull spent air in, recirculating the air throughout your home. This means you want the spent air that is being pulled in to flow through your air filter before being pushed back out into your home. 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.

If you find yourself with an air filter that doesn’t have an arrow on it, check it again, as nearly all filters have it. Still not finding the arrow? In this case you’ll need to look at each side of the filter. The side with the wire frame should be facing outward and the side without it will be inside closer to the unit.

Pro Tip: Once you’ve got it figured out, draw the airflow direction arrow on the HVAC housing or ductwork with a permanent marker. The next time you change your filter, match up the arrows’ directions and viola, you’ve properly changed your air filter.
