Which Way Should the Air Filter Arrow Point?

When it comes to air filters, the arrow always points in the direction of the air flow. This means that if the filter is on the wall, the arrow should be facing the wall. Most air filters have arrows printed on the sides showing how they are supposed to be installed. These arrows should point in the direction in which air flows through the system, which is away from the supply ducts and (usually) towards the blower.

Fortunately, most air filters are designed to not fit properly unless they are inserted correctly. Look for the airflow arrows printed on the side of the air filter that indicate in which direction the filter should be inserted. It is shown in the image below. For any air filter, whether for an air conditioner or an oven, the ARROWS ALWAYS POINT IN THE DIRECTION OF THE AIR FLOW.

When installing a new air filter in the AC return duct, the arrows face inward to specify the direction in which the air flows. The return duct in your home is PULLING air. When air is being sucked in or sucked in, the arrows on the air filter should point INWARD, toward the duct. If the oven filter is installed upside down, the fibers will not properly filter the air, which may eventually cause damage to the unit.

Try not to shake or hit the old filter, as this could release the particles back into your home air. The air filter can accumulate a lot of dust, so it is important to always disconnect the power to the boiler. If the air filter does not have an airflow arrow, make sure that the wire mesh is facing the fan of your HVAC system, as this is the last surface that touches the air.
