You should change your return air filter every 1 to 3 months, depending on filter type, usage, and indoor air quality.
Yes, air filters are typically installed in the return air duct to filter dust and particles before air enters the HVAC system.
Common return air filter sizes include 16x20x1, 20x20x1, and 16x25x1 inches. The size varies based on the HVAC system design.
To change a return air filter, turn off your HVAC system, locate the return air grille, remove the old filter, insert a new filter with the airflow arrow pointing toward the system, and then turn the system back on.
Your return air filter is usually located behind the return air grille on a wall or ceiling, inside the air handler unit, or along the return duct near the furnace or air conditioner.
