What to Do If Your Can’t Find Your Air Filter

The air filter is a critical part of the HVAC system in your Edgewater, Maryland, home. Air passes through the filter with each cycle, leaving dust, dander, and other pollutants behind so you can breathe easily. If your filter doesn’t get changed at least once every three months, it’s probably too dirty to do its job. Know where your filter is so you can keep up with this critical maintenance task.

Locate the Return Air Duct

The air filter in your HVAC system is usually located where the return air duct meets the air handler. On a horizontal unit, you’ll see the return duct coming in through the side of the unit with the filter along the side of the air handler as well. If you have a vertical air handler, look for the filter either above or below the unit, depending on whether the air handler enters from the top to the bottom.

If you don’t find the filter by the return air duct, look for it behind a return air grill on the wall. Alternately, you may find an air grill on the ceiling with the filter concealed behind. The filter looks like a mesh screen encased in a thin box.
