Which way should an air filter face?
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.

What is the direction of air flow?
Air always flows from a high-pressure area to a low-pressure area, much like water running downhill. Therefore, without an effective barrier, air outside a home at a higher pressure will always attempt to enter the home.
Why do air filters have a direction?
Air filters have arrows printed on the sides of them that show you which way they are supposed to be installed. These arrows should be pointing in the direction that air flows through your system, which is away from the supply ducts and (typically) toward the blower.
