Are BOROUX Proactive™ Fluoride filters compatible with my existing Berkey system and filters?

Yes, the BOROUX Proactive™ Fluoride filters are designed to be fully compatible with Berkey water filter. They are attached directly to the Black Berkey filters and therefore also hang in the lower tank, just like the Berkey 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 in conversions of other brands of gravity water filters, provided they use Black Berkey filters or BOROUX Foundation™ Black filters.
