Generic Replacement Black Purification Water Filter, Replacement for Berkey® BB9-2 Black Filters and Fluoride Filters (PF-2®) Combo Pack, 4 Pack, 1, Black/White

Compatible models: Replace Berkey BB9-2 Black filter and PF-2 fluoride filter combo pack and Travel, Large, Royal, Imperial, Light and Crown Berkey gravity filtration systems.

Longer service life: We recommend replacing each pair of black filters every 6,000 gallons and each pair of fluoride filters every 1,000 gallons, which will vary depending on the water.

Certified, Material safe: The water filter is NSF/ANSI 372 certified. We not only strictly control the filter material, but also produce the filter housing with lead-free and BPA-free materials.

Efficient filtration: The alternative filter for the BB9-2 filter is made of natural coconut activated carbon blocks to achieve a high chlorine adsorption rate, ensuring that harmful substances do not leach back into the water. The alternative filter for the PF-2 filter has been upgraded and now uses granular activated carbon and activated alumina as the filter medium, significantly improving the taste of the water.

Enjoy healthy water at all times: Convenient for camping and outdoor trips, family or holiday gatherings and other occasions, providing clean fresh water in case of an emergency. All of our water filters are lead-free and BPA free for peace of mind. The 4-piece set is only half of the original, and is made of 1:1 high-quality materials, saving costs and getting twice the result with half the effort
