We recommend cleaning the Coldstream FTO PLUS filter cartridges once a month, as well as the housings and other parts of your water filter. However, if you notice a change in the taste or smell of the water and/or a slowdown in the flow rate before then, this may indicate that your filters need cleaning.
Cleaning
PLEASE NOTE! Do NOT use soap when cleaning a filter element. Ensure that NO water enters the filter element’s shaft.
It is important that no water gets into the blue shaft of the filter element. So hold the filter element by its base and run it under cold running water for about 2 minutes. Whilst water is continuously running over the filter element, gently scrub the white ceramic outer surface with a scouring pad. Rinse it thoroughly and set it aside until it is ready to be reinstalled.
