How do you clean the ceramic elements?

The ceramic elements are very easy to clean. You simply remove them from the upper container, and while holding the threaded end of the filter upright, brush lightly downward toward the end cap. After you have lightly cleaned the surface, simply rinse and reinstall the element . Occasionally it will be necessary to lightly abrade the surface with the supplied green pad to restore full flow rate, perhaps after 3 to 5 brush cleanings.
