Pack of 2 x 7-inch activated carbon filters, replacement for water filter, black activated carbon filter, compatible with most gravity filters (5.08 cm per pack)

Compatible Models: The Filterlogic black water filter can replace the Berkey BB9-2 water filter and Berkey gravity filter systems, including the Travel, Big, Royal, Imperial, and Crown Series. The precise design of the washer and wing nut ensures a secure connection to prevent leaks. Please rinse the filter for 1 minute before use by connecting it to the faucet. Note: If the faucet is not fully compatible, some splashing may occur, but this will not affect the product. High-Efficiency Filtration: The black water filter, with the same high purification capacity as the original filter, can reduce up to 99% of chlorine. It can also reduce heavy metals, sediment, chlorine, sand, rust, odors, and large particles in spring water, improving the taste of the water. Certification, Safe Materials: The Filterlogic water filter has passed NSF/ANSI 42 and 372 certification. Our filters use high-quality natural activated carbon made from coconut shells. We strictly control the filtration materials and produce them with lead-free and BPA-free materials to guarantee excellent filtration performance and user safety. Please note that the TDS level does not fully indicate water quality, and our filters do not lower the TDS value. Economical choice: We recommend replacing the black filters every 1000 liters per pair, which can save 45,000 bottles of water. This saves you time and money on frequent replacements.
