Abstract
A cleaning system and method of cleaning filters that removes the ash in the plugged regions is disclosed. The filter is subjected to vibrations, which serve to loosen trapped and packed retentate from the filter. The loosened retentate is then captured by a collection bin. The cleaning system can be integral with the intended application, such as within an automobile. In another embodiment, the cleaning system is a separate cleaning station, where the filter is removing from its intended application, cleaned, and then reinstalled.
