In a 2019 Jeep Compass, there are two air filters to know about: the engine air filter, located in the engine bay, and the cabin air filter, located inside the vehicle behind the glove box. This article explains exactly where to find each filter, how to access it, and what to watch for when replacing it.
Engine air filter: location and replacement steps
Where to find the engine air filter
The engine air filter sits in a rectangular black plastic housing on the passenger side of the engine bay. It is connected to the intake tube that leads to the throttle body. The housing is secured with clips or screws that you can release to access the filter element.
Accessing the filter is typically straightforward and can be done with basic hand tools. Always ensure the engine is cool before opening the housing to avoid burns or injury.
- Open the hood and locate the large rectangular air box on the passenger side.
- Release the clips or remove the screws securing the cover and lift the lid off.
- Remove the old filter element and inspect it for excessive dirt, oil, or damage.
- Insert a new filter with the correct orientation (arrows on the filter usually indicate airflow direction).
- reseal the housing, reattach clips or screws, reconnect any hoses, and close the hood.
Concluding note: After replacing, check that the air box seals properly to prevent unfiltered air from entering the intake. If uncertain, consult the owner's manual or a technician for the exact steps for your trim level.
Cabin air filter: location and replacement steps
Where to find the cabin air filter
The cabin air filter for the 2019 Compass is located behind the glove box. Access typically requires lowering the glove box by releasing its stops or damper, then removing a cover to reveal the filter housing inside the dash.
Working inside the dash area can vary by trim, so take care not to damage hinges or components while lowering the glove box.
- Open the glove box and, if present, detach the damper or collapse the sides to allow the box to drop down fully.
- Find the rectangular cabin air filter housing behind the glove box and remove the cover.
- Remove the old filter, noting the correct orientation of the new one (usually indicated by arrows).
- Install the new filter, reseal the housing, and reclose the glove box, ensuring it latches properly.
- Test the HVAC system to confirm airflow is smooth and there are no whistling noises from a mis-seated filter.
Concluding note: Replacing the cabin filter helps maintain interior air quality and HVAC efficiency. If you notice musty odors or reduced airflow, a cabin filter replacement is a common remedy.
Maintenance tips and replacement intervals
Replacement intervals vary by environment and driving conditions. As a general guideline, plan to replace the engine air filter about every 30,000 miles (48,000 km) under normal conditions, but sooner in dusty or harsh environments. The cabin air filter is commonly changed every 12,000–15,000 miles (19,000–24,000 km) or about once a year, again depending on usage and local air quality. Always refer to the vehicle’s owner manual for the exact recommendations for your specific trim and regional conditions.
Tip: If you drive in heavy dust, construction zones, or high pollen areas, consider inspecting or replacing filters more frequently to maintain performance and air quality inside the vehicle.
Summary
In the 2019 Jeep Compass, the engine air filter is housed in a rectangular box in the passenger-side engine bay, while the cabin air filter sits behind the glove box inside the dash. Replacing both filters is a manageable DIY task with basic tools, and doing so helps protect engine performance and interior air quality. Always confirm steps with the owner’s manual for your exact trim level and consult a professional if you’re unsure.
