AQUA CREST NSF/ANSI 42&372 Certified Water Filter, Replacement for Berkey® Gravity Water Filter System, Berkey® Black Purification Elements, Pack of 4

AQUA CREST gravity filter replacements are designed for Black Berkey Elements–style systems (Travel, Light, Big, Royal, Imperial, and Crown series) and the AQUACREST AQ-TN gravity system; they are not sourced by or sponsored by Berkey, as AQUACREST is an independent brand. Made with natural coconut activated carbon, they are designed to help reduce chlorine (up to 99%), taste and odor, sediment, larger particles, and certain heavy metals for better-tasting water in outdoor or emergency use (does not reduce TDS). For best performance, replacement is recommended at up to 6,000 gallons per pair, depending on local water conditions. The set is designed for a secure, leak-resistant fit, can be used as a pair alongside a compatible fluoride filter, includes a priming button, and should be flushed for about 1 minute before first use (minor splashing may occur if the faucet connection varies).
