The 2020 Ford Explorer ST does include a cabin air filter as part of its HVAC system. The filter helps clean the air entering the cabin and is typically located behind the glove box, with replacement needed at regular maintenance intervals. This article explains where it is, what to expect from the filter, and how to inspect or replace it yourself.
Cabin air filter basics
A cabin air filter cleans outside air before it enters the vehicle’s interior, reducing dust, pollen, and odors. In modern Ford SUVs like the Explorer ST, many models use an activated carbon (carbon-adsorbing) filter to target odors and pollutants more effectively. Regular replacement is important to preserve airflow and cabin air quality, especially for drivers with allergies or in high-pollution environments.
Explorer ST specifics
Location and filter type
For the 2020 Explorer ST, the cabin air filter is typically installed behind the glove box. Access is gained by lowering the glove box and opening the filter housing. The filter is usually an activated carbon type, designed to trap dust, pollen, road grime, and odors before air is recirculated into the cabin.
What it filters and maintenance
The filter helps improve overall cabin air quality and HVAC efficiency. Replacement intervals vary by environment and driving habits, but a general guideline is every 12 months or 12,000–15,000 miles, whichever comes first. If you drive in heavy traffic, dusty conditions, or with occupants who have allergies, you may want to replace more frequently. Always refer to the owner’s manual for the exact specification for your vehicle.
Accessing and replacing the filter
If you plan to replace the cabin air filter yourself, follow these steps in order to access and install a new filter correctly.
- Park the vehicle, set the parking brake, and turn off the engine.
- Open the glove box and locate the dampers on the sides; gently press in or disconnect the dampers to allow the glove box to drop down fully.
- Behind the glove box, locate the rectangular filter housing and remove the filter cover by unfastening or sliding it out, depending on your model.
- Take out the old filter and note the orientation arrows printed on the frame (they indicate the correct direction of airflow).
- Insert the new cabin air filter with the arrows pointing in the same direction as the original (airflow from outside the cabin toward the evaporator).
- Reinstall the filter housing cover, reattach the glove box damper, and carefully close the glove box.
- Run the HVAC system on fresh air for a few minutes to verify proper airflow and ensure everything is seated correctly.
Replacing the cabin air filter restores filtration efficiency and can improve HVAC performance and odor control in the Explorer ST.
Maintenance tips for cabin air quality
These quick tips help keep the cabin air system working well between replacements.
- Check the filter visually when replacing it to ensure it is not clogged or overly dirty.
- Use the correct filter type specified for the Explorer ST (often activated carbon). Avoid generic filters that don’t meet the vehicle’s filtration standards.
- Consider replacing the filter sooner if you notice reduced airflow from the vents or a persistent musty odor.
- Keep the exterior HVAC intake clear of debris (usually located near the front grille) to maximize filtration effectiveness.
Following these tips can help maintain a clean, efficient HVAC system and improve your overall cabin experience in the Explorer ST.
Summary
In short, yes—the 2020 Ford Explorer ST does have a cabin air filter. It’s typically located behind the glove box and is often an activated carbon type. Regular inspection and replacement—roughly every 12 months or 12,000–15,000 miles, depending on usage and environment—help maintain air quality and HVAC performance. Always consult your owner’s manual for the exact filter specification and replacement procedure for your specific vehicle configuration.
