Air Flow Filter Arrow

It s a strangely surprising task changing your home air filters.

Air flow filter arrow.

When you install a new air filter into the ac return duct the arrows face inward to specify which way the air is flowing. When changing furnace filters many people wonder where the arrow of the filter should point towards. These arrows are always meant to point in the direction of the airflow. The arrows on any air filter need to point in the same direction the air is flowing.

Here s an easy way to figure out which way the air flow arrow goes. The arrow should always point in the direction the air is flowing. Look on the new filter for airflow arrows that are imprinted along the sides of the filter. If there is no arrow the side that is stronger or reinforced by cardboard or wire mesh is the side the arrow should be pointing to.

Another way of determining the. The front side of the filter is the filter media commonly called pleats. It means the arrow faces the unit or in other words facing inside the space you re putting it into. 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.

In other words the air travels from the tail of the arrow toward its point. The arrow should always point towards the return. There s an arrow on the box and it says to point in the direction of air flow but what does that mean. Like many you may be wondering why the arrow should point in the direction the air flows.

The answer lies in the way the air filter is built. Generally the edge of the filter is marked with an arrow which points in the direction of the airflow.
