2x Fluoride Reducing Gravity Filter

This set delivers two activated carbon water filter elements designed for Berkey gravity systems needing PF-2–style replacement. Each measures ~6.5″ × 2.5″ and weighs ~340 g. They reduce fluoride, arsenic and chlorine when installed beneath Black Berkey elements. Each filter ships with its own tan rubber priming button — used to seal the filter end against a cold faucet for priming. Steps include gentle pressure application, slow cold-water flow, and flushing both ends for at least 30 seconds until water flows visibly clear. Final verification is performed by examining filtered water in daylight or under room lighting for residual cloudiness. Only two filters and two priming buttons are included — no additional components or documentation beyond essential priming guidance.
