Two air filters — one engine air filter and one cabin air filter — keep both the powertrain and the interior air clean. The engine filter protects engine performance by filtering intake air, while the cabin filter cleans the air inside the vehicle. Some trims offer an activated-charcoal cabin filter for extra odor control.
Filters in the 2020 Ford Explorer
Here is a concise look at the two filters in this model, where they are located, and what they do.
- Engine air filter — Located in the engine compartment, typically in the intake box. It cleans incoming air to protect engine performance and efficiency. Typical replacement interval is about 30,000–45,000 miles, depending on driving conditions and the owner's manual recommendations.
- Cabin air filter — Located behind the glove box or under the dashboard, part of the HVAC air intake. It filters dust, pollen, and odors for the interior. Typical replacement interval is about 15,000–30,000 miles; more often in dusty or urban environments.
These two filters work together to maintain engine performance and interior air quality for drivers and passengers.
Notes on variations by trim
Some trims offer an activated-charcoal option for the cabin filter that enhances odor filtration. Availability depends on the specific trim level and factory options. Check your owner's manual or with a Ford dealer for exact configuration on your vehicle.
Maintenance and replacement intervals
To keep conditions optimal, replace filters according to or sooner than the recommended schedule, especially in harsh environments or during allergy season. Here are general guidelines:
- Engine air filter — Replace every 30,000–45,000 miles under normal conditions; inspect sooner in dusty or off-road use.
- Cabin air filter — Replace every 15,000–30,000 miles; more frequent changes in dusty areas or heavy traffic; monitor airflow and odors for signs of deterioration.
Always refer to the official maintenance schedule in your Ford owner's manual or consult a dealer for the exact intervals for your trim and regional conditions.

In summary, the 2020 Ford Explorer has two air filters: an engine air filter and a cabin air filter. Replacement intervals typically range from 15,000–30,000 miles for the cabin filter and 30,000–45,000 miles for the engine filter, with variations based on environment and trim. Regular checks help maintain performance and interior air quality.
