Key item features

  • Compatibility (Replacement/Compatible With): These black carbon filters are replacement for Berkey BB9-2 black filters and are compatible with Berkey-style gravity systems in the Travel, Big, Royal, Imperial, Light, and Crown series. They are also compatible with the Waterdrop gravity-fed water filter system. Please note: this is a compatible replacement part and is not sourced by or sponsored by Berkey; Waterdrop is an independent brand. Before first use, flush the filter for 1 minute by connecting it to a faucet. If the faucet connection is not fully compatible, minor splashing may occur but should not affect use.
  • Efficient Filtration: Made with natural coconut shell activated carbon, these filters help reduce sand, rust, sediment, odor, large particles, and can achieve up to 98% chlorine reduction (tested by a third-party laboratory) to improve taste. Note: This filter does not reduce TDS, and TDS is not a complete indicator of water quality.
  • Leak-Resistant Design: The filters are designed for a secure, leak-resistant fit when installed properly in compatible systems, helping provide dependable daily use.
  • Service Life Guidance: Each pair is rated for up to 6,000 gallons before replacement, depending on local water conditions and usage patterns.
  • Support: If you have questions about installation or compatibility, customer support is available to help.
