In modern Honda CR-Vs, there are two primary air filters: one for the engine and one for the cabin. While some very early or market-specific models may differ, the standard setup in today’s lineup is two filters. This article explains what each filter does, where to find it, and how to replace them.
What are the two air filters and what do they do?
The engine air filter cleans the air that enters the intake, helping optimize combustion and engine performance. The cabin air filter cleans the air circulating inside the vehicle’s cabin, improving air quality for passengers. Some cabin filters are equipped with activated carbon to reduce odors and pollutants.
- Engine air filter: located in the engine compartment, inside a rectangular plastic housing attached to the intake tubing. It protects the engine by filtering dust, dirt, and debris from entering the combustion chamber.
- Cabin air filter: located in the HVAC housing, typically behind the glove box or under the dash. It cleans the air that blows through the vents and, in carbon-activated variants, helps reduce odors and pollutants.
Knowing there are two separate filters helps explain maintenance needs and why regular replacement matters for both engine performance and passenger comfort.
Where they are and how to replace them
There are two distinct replacement procedures, one for each filter. Below are the standard steps for typical CR-V models.
Engine air filter replacement steps
Follow these steps to replace the engine air filter. Note that steps can vary slightly by year and trim, so always refer to your owner's manual for model-specific instructions.
- Park the vehicle on a flat surface and turn off the engine. Open the hood and locate the engine air filter housing, usually on the side of the engine bay near the front.
- Unclip or unscrew the housing cover and remove the old filter, taking note of orientation.
- Clean out any debris from the housing with a clean cloth or compressed air if available.
- Insert the new filter in the same orientation as the old one, ensuring it seats properly.
- Reattach the housing cover and secure the clips or screws firmly.
Keeping the engine air filter in good condition helps maintain performance, fuel economy, and emissions compliance. Typical replacement intervals are around 20,000–30,000 miles (32,000–48,000 km) or as advised in the owner's manual, especially in dusty or high-mileage driving conditions.
Cabin air filter replacement steps
Replacing the cabin filter improves interior air quality and HVAC performance. The access point is usually behind the glove box or under the dash, depending on the model year.
- Turn off the vehicle and locate the cabin air filter access panel, typically behind the glove box or under the passenger-side dash.
- Remove the panel by sliding, unclipping, or loosening screws as required.
- Gently pull out the old filter and note its orientation (arrow indicating airflow).
- Insert the new filter with the correct airflow direction and reinstall the access panel.
- Test the HVAC system by turning the fan on and ensuring air flows smoothly through the vents.
Cabin filters are usually changed more frequently than engine filters, often every 15,000–25,000 miles or 12–24 months, though intervals can vary by environment and driving conditions.
Model-year and regional notes
In the current generation and most recent model years, Honda CR-Vs use two filters—engine and cabin. Some older generations or non-U.S. markets may have had variations in filter placement or presence, so it’s best to confirm by consulting the owner's manual or a dealership service bulletin for your specific year and region.
Summary
Bottom line: a Honda CR-V typically houses two air filters—one for the engine and one for the cabin. Regular inspection and timely replacement of both filters help protect engine performance and maintain interior air quality. Always refer to your vehicle’s manual for the exact replacement intervals and procedures tailored to your model year.
