There are multiple cases when multiple air filters are needed. Understanding the parts of your central air system matters because it helps explain instances of multiple air filters being used in various places. This helps keep air flowing throughout the home and keeps your temperature stable Air from the home is pulled back through the return ducts, chilled or heated to the right temperature, then sent back through the duct system into the home.Air from the outside the home is drawn into the unit, chilled or heated to the right temperature, then sent into the home.Your home’s AC air duct system does two things: This central air component also typically contains the blower, evaporator coils, and furnace.
