Which Side of an Air Filter Should Face Down?

When it comes to installing an air filter, it's important to know which side should face down. Air filters have arrows printed on the sides that indicate the direction of air flow. These arrows should point away from the supply ducts and towards the blower. The side of the filter with a metal structure should face outward, away from the unit.

For any air filter, whether for an air conditioner or an oven, the arrows always point in the direction of air flow. When installing a new air filter in the AC return duct, the arrows should face inward to show that air is being pulled in. A downflow oven takes air from the top, heats it, and then blows it into the ductwork. In this case, the filter will be located at the top of the fan and the arrow should point downwards.

The metal structure on the filter serves as a support to maintain its rigidity as air passes through it. It's important to always disconnect the power to the boiler before changing the air filters. This task may seem easy but it's often forgotten. To ensure optimal efficiency and indoor air quality near Coachella Valley, make sure your air filters are installed correctly.

When air filters become clogged with dust, dirt and debris, they can no longer improve indoor air quality. A dirty filter will block airflow through the HVAC system, causing it to work harder and consume more energy. This can damage your system and increase your energy bills. It's important to routinely check your air filters to prevent them from becoming clogged with dirt, dust, or debris.

This will help keep your HVAC system running efficiently and ensure that you and your family are breathing clean air.
