The 2018 Honda CR-V uses two air filtration components: an engine air filter and a cabin air filter. The engine filter protects the intake and engine from dust, while the cabin filter cleans the air that enters the passenger area through the HVAC system.
Two filters serving different purposes
The CR-V relies on separate filtration for the engine and the interior. The following list identifies each filter, its role, and where to find it.
- Engine air filter: Located in a square or rectangular housing in the engine bay, typically on the passenger side front. It filters air entering the engine for combustion and performance.
- Cabin air filter: Located behind the glove box inside the dash, it filters air entering the passenger compartment via the HVAC system.
Keeping both filters in good condition helps maintain engine efficiency and interior air quality. Regular checks and timely replacements are part of routine maintenance.
Where to locate and how to replace
Engine air filter
Access and replacement steps for the engine air filter help keep the engine breathing clean air.
- Open the hood and locate the engine air filter housing on the passenger side of the engine bay.
- Unclip or unscrew the housing lid, then remove the old filter.
- Clean the inside of the housing if there is debris, insert the new filter with the correct orientation (typically with the ribbed side facing upward or as indicated by the housing).
- Reattach the housing lid securely and close the hood.
Refer to the owner's manual for exact tool requirements and any trim-specific instructions.
Cabin air filter
Access and replacement steps for the cabin air filter keep the interior air fresh and reduce pollen and dust exposure.
- Open the glove box and remove contents; press in the sides to release any dampers or stoppers if present.
- Remove the cabin air filter door or panel behind the glove box and take out the old filter.
- Insert the new filter with the airflow arrows pointing in the correct direction, then reinstall the door/panel.
- Reassemble the glove box and run the HVAC fan briefly to ensure smooth airflow.
Again, consult the owner's manual for the exact access point and any trim-specific steps.
Maintenance tips and replacement intervals
Here are typical replacement intervals for the 2018 CR-V under normal driving conditions. Actual needs vary by environment and driving habits.
- Engine air filter: commonly replaced every 30,000 miles (48,000 km); more frequently in dusty or harsh conditions.
- Cabin air filter: typically replaced every 15,000–30,000 miles (24,000–48,000 km); more often in urban areas with pollution or high pollen counts.
For precise intervals, check the owner's manual or follow guidance from a Honda dealer, especially if you operate in extreme or dusty climates.
Summary
In summary, the 2018 Honda CR-V has two air filters: one for the engine and one for the cabin. Regular inspection and timely replacement of both filters help maintain engine performance and interior air quality, with specific replacement intervals varying by environment and driving conditions.
