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