BOROUX Proactive Fluoride Add-On Filter

An alumina-free fluoride add-on filter that reduces up to 99% of fluoride from your drinking water. The BOROUX Proactive uses a patent-pending upflow design and dual-layer nano-carbon filtration housed in a 304 stainless steel shell — up to 1,000 gallons per pair. Compatible with BOROUX Foundation and Black Berkey elements in the lower chamber.

Options

The Proactive filter sits in the lower chamber, attached to a Foundation or Black Berkey® filter in the upper chamber. The reusable 304 stainless steel shell drives water through a patent-pending upflow design — routing water from the bottom up to slow the flow and maximize contact time with the dual-layer nano-carbon media. This optimized interaction is designed to enhance fluoride reduction beyond what conventional designs achieve.

The BOROUX Proactive™ Fluoride Add-On Filter is a high-performance, alumina-free fluoride reduction filter that pairs with BOROUX Foundation and Black Berkey® elements. Its patent-pending upflow design and dual-layer nano-carbon media are designed to reduce fluoride by up to 99%.
