K&N Cabin Filter Cleaning Kit — 12 oz Cleaner + 8 oz Refresher | Restores Airflow & Reduces Odors

K&N's Cabin Filter Cleaning Kit is a two-spray system that cleans and refreshes washable K&N cabin air filters to restore airflow and reduce odors.

Keep the air inside your vehicle fresher and the cabin filter working closer to its original capacity with this service kit. The set includes a 12 oz pump spray cleaner and an 8 oz pump spray refresher, plus step-by-step instructions. The formulas are biodegradable and designed specifically for K&N washable cabin air filters, breaking down trapped dirt, dust and road grime without harsh solvents.

How does the cleaner remove built-up dirt and debris?

The 12 oz pump spray cleaner loosens and dissolves accumulated particles that clog filter fibers. It penetrates the filter media so contaminants release more easily during rinsing, shortening cleaning time and improving results.

• Spray directly onto both sides of the filter for thorough coverage
• Allows contaminants to be rinsed away with low-pressure water
• Formulated to work safely with K&N filter materials

What does the refresher spray do after cleaning?

The 8 oz refresher spray treats the filter after it dries to neutralize common odors and leave a light, clean scent. It helps address the source of many smells rather than just masking them, making the cabin air more pleasant.

• Applies as a finishing step after filter is fully dry
• Reduces lingering odors caused by trapped particles
• Biodegradable formula designed for enclosed vehicle use

How do I use the kit for best results?

Use the cleaner first, allow dwell time, rinse gently, let the filter dry completely, then apply the refresher. Following the included instructions helps prevent damage and ensures the filter regains as much airflow and filtration performance as possible.

• Spray cleaner, wait several minutes for penetration, then rinse from clean side out
• Air-dry the filter fully—avoid heat sources—and confirm no moisture remains
• Lightly spray the refresher evenly and let it set before reinstalling the filter

Will this kit work on any cabin filter?

The kit is formulated for K&N washable cabin air filters and is optimized for their materials. While the cleaner may work on other washable filters, results and compatibility are best when used with K&N products.

• Guaranteed compatibility with K&N washable cabin filters
• Safe, biodegradable ingredients reduce risk to filter media
• Includes clear, manufacturer-recommended instructions
