Yes, the BOROUX Proactive™ Fluoride filters are designed to be fully compatible with Berkey water filters. They attach directly to the Black Berkey filters and are therefore also placed in the lower chamber, just like Berkey’s fluoride filters. This allows you to continue using your existing Berkey system while benefiting from BOROUX’s advanced fluoride-reducing technology. Of course, they also fit into the housings of other brands of gravity-fed water filters, provided that Black Berkey filters or BOROUX Foundation™ Black filters are used.
