Two: one engine air filter and one cabin air filter.
In the 2020 CR-V, the filtration system covers both the engine’s air intake and the cabin air you breathe. The engine air filter traps dust and debris before they can enter the engine, helping maintain performance and fuel efficiency, while the cabin air filter cleans outside air entering the HVAC system, reducing pollen, dust, and odors inside the vehicle.
Two filters and their locations
Below is a quick guide to the two filters, where they reside, and their roles in the CR-V’s systems.
- Engine air filter — located in the engine compartment, inside a rectangular housing. It protects the engine by filtering incoming air used for combustion.
- Cabin air filter — located behind the glove box or near the passenger-side of the dashboard. It cleans the air circulated through the HVAC system to improve interior air quality.
Replacing both filters as part of routine maintenance helps preserve engine performance and interior comfort. The exact replacement intervals can vary based on driving conditions, pollen levels, and dust exposure.
Recommended maintenance intervals
Typical guidance is to replace the engine air filter about every 30,000 miles (48,000 km) and the cabin air filter about every 15,000 miles (24,000 km). In dusty or high-pollen environments, more frequent changes may be beneficial. Always check the vehicle’s owner’s manual or consult a Honda service center for your specific model and regional guidance.
Summary
The 2020 Honda CR-V employs two air filters—an engine air filter and a cabin air filter. They’re located in the engine compartment and behind the glove box, respectively. Adhering to recommended replacement intervals helps maintain engine performance and interior air quality.
