The cabin air filter is located behind the glove box on the passenger side, and you access it by lowering the glove box and removing the access panel.
In most Buick Encore models from 2013 to 2019, the filter sits in a rectangular housing behind the glove box on the passenger side. Replacing it is a quick DIY job—typically 5 to 10 minutes—and usually requires no tools beyond a new filter and a bit of glove box maneuvering. Some model years may require detaching a glove box damper or squeezing the sides to drop the box.
Accessing the filter
Before you begin, gather supplies: a replacement cabin air filter of the correct size, a clean rag, and gloves. The steps below describe how to reach and replace the filter.
- Open the passenger-side glove box and remove its contents.
- Squeeze the sides of the glove box to release the stops or gently lower the box; in some years you may need to detach the glove box damper.
- Look for a rectangular access panel or opening behind the glove box and remove or unclip it to reveal the filter housing.
- Slide the old filter out, noting its orientation for the new filter.
- Insert the new filter with the arrows pointing in the correct direction, typically toward the HVAC housing.
- Reattach the access panel, lift the glove box back into place, and close it.
Note: Some Encore models may use a different filter size or configuration; consult your owner's manual or a dealership service bulletin for model-year specifics.
When to replace and signs
Check the cabin air filter at least once a year or every 12,000 miles, whichever comes first. Replace sooner if you drive in dusty areas, suffer from seasonal allergies, or notice reduced airflow, musty odors, or increased HVAC noise.
Additional tips
Dispose of the old filter properly and replace it with the correct grade for your vehicle. If your Encore has an A/C recirculation indicator, reset it after installing the new filter per the owner’s manual.
Summary: For Buick Encore owners, the cabin air filter sits behind the glove box on the passenger side and is accessible by lowering the glove box and removing a small panel. Replacement is a straightforward DIY task that takes about 5–10 minutes, and keeping it fresh helps maintain cabin air quality and HVAC performance.
