The Allstar Filter cleaning station simplifies and speeds up the process of servicing 14" washable air filters. Simply spray your air filter with a cleaner/degreaser as recommended by filter manufacturer, allow a brief time to soak then flush clean with a garden hose. You can allow your air filter to dry completely by rotating as necessary. Once the filter is dry, use stand to rotate filter for even application of filter oil, if applicable. For use with washable filter elements only. Filter not included.
