The 2015 Chevy Equinox has two air filters: one for the engine's intake and one for the cabin. This article explains their roles, where to find them, and basic maintenance tips.
Two Filters, Two Roles
In this model year, air filtration is split between the engine and the interior to protect performance and air quality.
- Engine air filter — located in the engine compartment, it cleans the air drawn into the engine for combustion, helping performance and efficiency.
- Cabin air filter — located behind the glove box (or under the dash depending on trim), it cleans outside air before it enters the passenger compartment to reduce dust, pollen, and odors.
Knowing these roles helps you plan maintenance and understand why each filter matters for both power and comfort.
Maintenance and Replacement Guidelines
Replacement intervals vary with driving conditions and environment. The following ranges are commonly recommended by owners’ manuals and service guides for typical use:
- Engine air filter: about 30,000 to 45,000 miles under normal conditions; replace sooner in dusty or severe service scenarios.
- Cabin air filter: about 15,000 to 25,000 miles, or at least once a year; more frequent changes may be needed in heavy traffic, dusty areas, or high pollen seasons.
Always refer to the owner's manual or a GM service technician for the exact interval for your vehicle and trim level.
Where to Look and How to Replace (Overview)
Engine air filter replacement overview
The engine air filter sits in a rectangular housing in the engine bay. To inspect or replace, release the clips or screws on the housing, remove the old filter, clean the housing, insert a new filter with the correct orientation, reseal the housing, and resecure.
Cabin air filter replacement overview
The cabin filter is typically behind the glove box. To replace, open the glove box to access the filter cover, remove the old filter, clean the housing, insert a new filter with the correct orientation, and reassemble the glove box area. If you notice reduced airflow or odors, it's a good time to check the cabin filter.
Note: Steps can vary by trim; consult the owner's manual or a professional for specifics.
Summary
Bottom line: the 2015 Chevy Equinox has two air filters—an engine air filter and a cabin air filter. They serve different purposes, and keeping them in good condition supports engine performance and cabin comfort. Regular checks and timely replacements according to driving conditions keep the vehicle running smoothly.
