detergent. The adhesive helps to retain the dirt particles, and when the filter is washed, the
detergent helps to release the used adhesive and contaminants from the media. To clean a dirty
filters, rinse it with a moderate-to-heavy stream of warm water. High-powered steam cleaning or chemical dips are unnecessary and are not recommended. Re-spraying with Filter Coat will help maintain the filter's efficiency.
