Ceramic & Fluoride Filter Replacement Kit Upgraded Compatible with Berkey® BB9-2® White Filters & PF-2 Fluoride Filters, Works with Gravity Water Filtration System, 4 Pack Combo

Enhanced Compatibility: This gravity water filter is fully compatible with Berkey Gravity Filtration System, including Travel, Big, Royal, Imperial, Crown Series. Carefully designed washers and wing nuts are securely connected to prevent leaks

Washable and Reusable: We recommend replacing the white fluoride filter every 1,000 gallons per pair to maintain peak performance. The external ceramic filter is washable and reusable, providing long-lasting water filtration without the need for electricity. Regular daily use of the gravity filtration system ensures delicious water for at least six months

0.1-Micron Filtration: The ceramic filter utilizes a ceramic and silver-infused carbon block gravity-fed 2-stage filtration system, providing precise 0.1-micron filtration. The white fluoride filters utilize a natural mineral synthesis material called Carbonate Apatite as the filter medium. They efficiently absorb 99% of residual chlorine and fluoride and effectively filter various impurities such as sand, rust, sediment, and unpleasant tastes

Certified Safety Upgrades: The ceramic filter uses a two-stage ceramic carbon block gravity-fed filtration system with an outer ceramic casing and an inner silver-infused coconut shell activated carbon block. This design helps prevent the growth of harmful contaminants and is NSF/ANSI 42 certified to ensure your family's water safety

Maintenance Suggestions: After some time, the ceramic filter may accumulate a significant amount of impurities on the ceramic surface, reducing water flow. To address this, we suggest using the provided sandpaper to gently scrub the ceramic surface under cold water, eliminating clogged pores and revealing a new layer for continued use
