Boroux Foundation Black Replacement Water Filter for Berkey BB9-2 & Gravity Systems

Effortless, high-grade filtration for Boroux and Berkey systems

Upgrade your hydration routine with the Boroux Foundation Black Replacement Water Filter, designed to fit the BOROUX legacy system and a wide range of gravity-fed filters. It directly replaces Berkey BB9-2 fittings and is compatible with Travel Berkey, Big Berkey, Berkey Light, Royal Berkey, Imperial Berkey, and Crown Berkey models. This filter brings premium filtration straight to your home, helping you enjoy clearer, better-tasting water with confidence about compatibility.

At the core is advanced filtration technology. The filter uses premium activated carbon and is NSF/ANSI/CAN 372 certified by WQA, engineered to reduce chlorines and other common contaminants. While results can vary with water quality, you may notice a fresher taste and a more inviting aroma after purification. The filtration media is designed to preserve essential minerals while targeting taste-impacting compounds, making everyday water use—drinking, cooking, and mixing—feel more approachable.

The foundation also features a reinforced Stem Saver design. This re-engineered stem strengthens the filter’s most vulnerable point, helping it endure regular cleaning and handling. The improvement is built into the product to support durability over time, so you can rely on consistent performance during routine maintenance.

With robust longevity in mind, a set of two filters can deliver up to 12,000 gallons of filtered water, offering a practical balance of performance and value for families, offices, or outdoor setups. Expect steady filtration across refills, making this a dependable choice for extended use without frequent replacements.
