AQUA CREST NSF/ANSI 42&372 Standard Water Filter, Replacement for Berkey® Gravity Water Filter System, Berkey® BB9-2® Black Filters & PF-2® Fluoride Filters

This combo set is replacement for Black Berkey Elements (BB9-2) and PF-2 Fluoride Reduction Elements, and compatible with Berkey-style gravity systems (Travel, Light, Big, Royal, Imperial, and Crown series) as well as the AQUA CREST gravity system (Model AQ-TN-A-FS); it is a compatible replacement part that is not sourced by or sponsored by Berkey, and AQUACREST is an independent brand. Made with a natural coconut activated carbon block and a food-grade fluoride-reduction media, it helps reduce chlorine (up to 99%), fluoride, certain heavy metals, taste and odor, sediment, and larger particles (third-party tested), while not lowering TDS. The package includes two black filters, two fluoride filters, and one priming button; for best results, flush the black filters for 1 minute and the fluoride filters for 20 seconds before first use, and replace the black filters at up to 6,000 gallons per pair and the fluoride filters at up to 1,000 gallons per pair (actual service life varies with local water conditions). If a faucet connection isn’t fully compatible, minor splashing may occur but won’t affect use; support is available if you need help.
