Where is my air filter located?

Posted by Kelle Repass on Sunday, July 3, 2022
The air filter is usually located in the return air duct or blower compartment before the return air reaches the air handler. This allows the filter to clean the air coming from your house before it enters the HVAC unit.

Subsequently, one may also ask, where is my air filter in my house?

Here are some common locations.

  • Behind a register in your wall or on the ceiling.
  • Behind a register in the floor (in older homes).
  • On the HVAC unit near the air handler, which looks a bit like a furnace. Look for your air handler in the basement or the attic. The air filter slots into the air handler unit.
  • Additionally, which side of air filter faces out? On your new air filter, find the arrow that indicates the proper air flow direction. This tends to confuse everyone more than anything else. That arrow must always face toward the furnace and away from the return duct that carries the air in need of heating or cooling.

    Keeping this in view, where is the air filter located in my car?

    On most modern vehicles, the air filter is under the hood inside a rectangular cold air collector box that's located up near the front of the engine compartment. (Other vehicles, including those with carburetors, have big round metal air cleaners that are hard to miss.)

    Which way does an air filter go in?

    Luckily, most filters are made so they won't fit right unless they're inserted in the correct direction. There should be airflow arrows printed on the side of the air filter to indicate what direction the filter should be inserted. When you insert your new filter, the arrow should point toward the furnace.

    What happens if I run my AC without a filter?

    The biggest problem with running the AC without a filter is the dust/dirt that settles inside the AC system, restricting airflow over your evaporator coils. You see, your evaporator coils sit inside your AC air handler and are filled with cold refrigerant. This refrigerant is what actually cools the air.
