Black Berkey® water filters do not necessarily need to be cleaned every time you clean your Berkey® water purifier. Nevertheless, this is to be weighed against the quality of your water. If you live in an area where the water is much dirtier than normal, it may require more frequent cleaning of the elements to remove debris that can clog the pores of your Black Berkey® purification elements.

Regarding the frequency of filter cleaning, it can be assumed that it is necessary to do so when you notice that the flow rate starts to decrease considerably.
For hard water, cleaning should be done every month. In other cases, set a limit of 6 months maximum, so as not to reach the point where the filters become completely clogged.

How to clean your filters?

1. Start by emptying and disassembling the Black Berkey® Purification Elements from the Berkey® System. Then use a cleaning pad similar to a Scotch Brite pad or a stiff toothbrush and gently scrub the outside of the Black Berkey® Purification Elements under running (and cold) water.
2. Reboot the filters.
3. Reassemble the Black Berkey® purification elements in your Berkey® system and refill the upper chamber.
