How will this kit improve my cabin filter's performance?

Cleaning removes the particles and residues that reduce airflow and trap odors, helping the filter return closer to its original efficiency. The cleaner breaks up grime, and the refresher helps eliminate lingering smells left in the filter fibers.

• Lifts dust, pollen, and road film from filter pleats
• Restores air passage through the media for better airflow
• Reduces odor sources by treating contaminants directly

The kit contains a 12 oz pump spray of cabin filter cleaner, an 8 oz pump spray of cabin filter refresher, and printed cleaning directions. Apply the cleaner to loosen debris, rinse or shake out residue, let the filter dry, then apply the refresher to neutralize odors and finish the service.
