The BOROUX Proactive Fluoride Filter is a high-performance, alumina-free solution that removes up to 99% of fluoride. Its patent-pending upflow design and dual-layer nano-carbon filtration maximize contact time and filtration efficiency. Housed in durable stainless steel shells, it’s compatible with BOROUX Foundation and Black Berkey® filters, delivering up to 1,000 gallons of clean, fluoride-reduced water per pair. The fluoride filter is an add-on filter located in the lower chamber and must be attached to a filter housed in the upper chamber. The reusable stainless steel shell is required for use with Fluoride Filter. It supports our upflow design, which directs water from the bottom up—slowing the flow rate and increasing contact time between water and filtration media. This optimized interaction enhances fluoride reduction and overall effectiveness.
