We recommend cleaning the Coldstream FTO PLUS filter elements once a month, as well as the containers and other parts of your water filter. However, if you notice a change in the taste or odor of the water and/or a slowdown in the flow rate before then, this may indicate that your filters need to be cleaned.
Cleaning
IMPORTANT! DO NOT use soap when cleaning a filter element. Make sure that NO water gets into the filter element’s shaft.
It is important that no water gets into the blue stem of the filter element. So hold the filter element by the base and run it under cold running water for about 2 minutes. While water is continuously flowing over the filter element, gently scrub the white ceramic exterior with a scouring pad. Rinse it thoroughly and set it aside until it is ready to be reinstalled.
