There are two air filters in a Buick Verano: the engine air filter in the engine bay's intake housing, and the cabin air filter behind the glove box in the dash.
The engine air filter protects the engine from debris, while the cabin (HVAC) filter cleans the air that enters the passenger compartment. This guide explains where each filter is located and provides step-by-step instructions to replace them for common Verano model years.
Engine air filter location
The engine air filter is housed in a rectangular plastic box in the engine bay, typically on the passenger side near the front of the vehicle and connected to a plastic intake duct. Access is gained by releasing clips or removing screws that hold the lid in place.
Follow these steps to locate and replace the engine air filter. You may need basic hand tools if the housing uses screws rather than simple clips.
- Park on a flat surface, turn off the engine, and open the hood. Set the parking brake if needed.
- Locate the rectangular engine air filter housing in the engine bay, usually on the passenger side near the front and connected to the intake duct.
- Release the clips or remove screws that secure the housing lid, then lift the lid to expose the old filter.
- Take out the old filter and note its orientation (the filter has an arrow on its frame indicating airflow).
- Inspect the housing for any debris and wipe it clean if needed.
- Insert the new filter with the correct orientation, ensuring it sits snugly in the housing.
- Reposition the housing lid and secure it with the clips or screws you removed.
- Close the hood and start the engine to verify there are no unusual sounds and that the intake is functioning properly.
Replacing the engine air filter at regular intervals helps maintain engine performance and fuel efficiency.
Cabin air filter location
The cabin air filter is located behind the glove box. Access is gained by opening the glove box, dropping it down, and removing a cover or filter housing panel in the HVAC housing behind it.
To replace the cabin filter, follow these steps that apply to most Verano models. No special tools are typically required beyond basic hand tools if needed.
- Empty the glove box and gently remove items inside to gain clear access.
- Open the glove box fully and, if present, disconnect the limiting stop or damper so the box can drop down further.
- Look for the cabin air filter housing on the side of the HVAC unit behind the glove box; remove the housing cover or panel by releasing its clips or screws.
- Take out the old cabin filter and note the orientation of the airflow arrows on the filter frame.
- Clean the housing opening if there is dust or debris, then insert the new filter with the arrows pointing toward the HVAC unit.
- Reattach the housing cover or panel and secure the glove box damper/stop if removed.
- Return items to the glove box, close it, and run the HVAC system briefly to ensure proper airflow.
Regular replacement of the cabin filter improves cabin airflow, odor control, and overall HVAC performance.
Summary
In the Buick Verano, you’ll find two air filters: the engine air filter in the engine bay’s intake housing and the cabin air filter behind the glove box. Follow the step-by-step instructions to replace each filter, and consult your owner's manual for model-year-specific intervals and any variations. Proper maintenance helps keep engine performance and interior air quality at their best.
