2020 Ford F-250 Owner’s Manual — Interior Air Quality

The cabin air filter improves the quality of air in your vehicle by trapping dust, pollen and other particles.

You can locate the cabin air filter behind the glove box.

Replace the filter at regular intervals. See

Scheduled Maintenance (page 553).

Note: Make sure you have a cabin air filter installed at all times. This prevents foreign objects from entering the system. Running the system without a filter in place could result in degradation or damage to the system.

Note: Using an aftermarket cabin air filter could reduce cabin air filtration and climate control performance.
