How to Properly Install an Air Filter

Installing an air filter correctly is essential for maintaining the efficiency of your HVAC system and ensuring the best indoor air quality. Fortunately, most air filters are designed to not fit properly unless they are inserted in the right direction. To determine the correct direction, look for the airflow arrows printed on the side of the air cleaner. These arrows should point in the direction in which the air flows through the system, which is away from the supply ducts and (normally) to the blower.

If you're not sure when to change the filter, invest in an electronic air cleaner monitor that will tell you when it's time to replace it. It is important to always turn off the boiler power before changing the filter, as it can accumulate a lot of dust. When you insert the air cleaner incorrectly, you can't filter the air in your home efficiently, which can lead to a variety of maintenance issues. So if you have a ceiling or wall air return that uses a filter, make sure that the filter arrow points to the ceiling or wall.

If you have any questions about the air flow direction of the air filter, or if you want a cooling system repaired or installed in your home, contact Hyde's, your Coachella Valley air conditioning contractor. If your oven has a filter, it should be installed with the airflow arrow pointing towards the oven. If it is installed upside down, the fibers will not properly filter the air, which can eventually damage the unit. Some downflow ovens have a V-shaped filter system and need two filters placed in the compartment at a V-shaped angle. For optimal indoor air quality and efficiency near Coachella Valley, make sure your air filters are installed correctly. A dirty, clogged air filter will significantly impair the efficiency of your oven and air conditioner.

A horizontal oven draws in air on one side, heats it or removes heat to cool it, and blows the treated air into the duct network on the opposite side.
