How to Clean a K&N Cabin Filter


K&N CABIN AIR FILTER CLEANING INSTRUCTIONS

 

When your cabin air filter(s) get dirty, the filter can be cleaned and reused. K&N recommends servicing your K&N cabin air filter every 12 months or 12,000 miles. Best of all, the filter comes with a 10 year/100,000 mile limited warranty. Servicing your K&N cabin air filter is simple: just follow the following 6 steps.

 

1.REMOVE FILTER: Remove the K&N® cabin air filter from the cabin air filter housing and or cabin air filter tray. Handling with care, remove loose dirt and debris from the filter by tapping it with your hand or against a hard surface.


2. APPLY CLEANER: Spray a generous amount of K&N’s specially formulated cabin air filter cleaner P/N 99-0650 onto both sides of the filter, with a majority of it applied to the dirty side. Allow the cleaner to soak in for 10 minutes. Do not allow the cleaner to dry on the cabin air filter.


5. REFRESHING: Apply K&N cabin air filter Refresher™ P/N 99-0660 onto the cabin air filter element. Apply liberally, so that the entire area of the cabin air filter media is treated.


3. RINSE FILTER: Rinse off the filter element with cool or warm (not hot) water from the clean side out in order to flush the dirt out of the filter. It may be necessary to use your fingers on the hose, to apply light water pressure. Repeat steps 2 and 3, until the water flowing through the media is completely clear of any dirt and debris.



4. DRY: After rinsing, gently shake off excess water. Allow filter to dry naturally for 20-30 minutes. The filter does not need to be completely dry and can be slightly damp before moving to the next step.

5. REFRESHING: Apply K&N cabin air filter Refresher P/N 99-0660 (Part of the 99-6000 Kit) onto the cabin air filter element. Apply liberally, so that the entire area of the cabin air filter media is treated.



6. RE-INSTALL: Re-install the cabin air filter into the filter housing or tray. Follow original installation instructions that were provided with your K&N cabin air filter.
Use only K&N cabin air filter RefresherTM kit, and not K&N engine air filter Recharger kit. The above process is the only approved procedure for servicing your K&N cabin air filter.
