What is a Cabin Air Filter?
A cabin air filter is a rectangular pleated filter situated somewhere behind the dash (usually behind the glove compartment). Its job is to filter out pollutants (for example, dust, pollen, bugs, etc.) from the air entering the cabin through the vehicle's HVAC system.

How to Diagnose a Bad Cabin Air Filter
Got a hunch that your cabin air filter has gone bad? A visual inspection is in order. All you have to do is to find the cabin air filter in your Ford, pull it out, and then hold it up to a bright light to see if it shines through the filter. If it shines through, then the filter has some life left in it (but you can still replace it if you want). If you can't see any trace of the bright light through the filter, then chuck it out and put in a new one as soon as possible.

OEM Vs. Aftermarket Cabin Air Filters
Trying to decide between an OEM cabin air filter an aftermarket one? Let this guide help you reach a decision: Are OEM Ford Cabin Air Filters Better Than Aftermarket?
In a nutshell, the answer to the question is yes. OEM cabin air filters are far superior to aftermarket cabin air filters because:
- OEM air filters come with high quality pleated material that will last a long time, while aftermarket air filters usually come with cheap pleated material that won't last even half as long.
- OEM air filters are built with the right dimensions for your Ford model, while aftermarket air filters are built to universal specs and may require modification prior to installation.
- OEM air filters come with a warranty, while aftermarket air filters usually don't.
