Glacier Fresh Black Elements & Fluoride Filters BB9-2 Black Purification and PF-2 Fluoride Reduction Water Filter

The GF-S001A-1 black purification filters are designed to replace Black Berkey Elements BB9-2 and fit Travel, Big, Royal, and Imperial Berkey series gravity water filter systems.

The full weight depends on the specific gravity system size and how much water is added. Travel, Big, Royal, and Imperial Berkey series systems have different capacities, so check the system manual for the filled weight before moving the unit.

Filtered water should be kept in a clean covered container and used within a reasonable time. For the best taste and freshness, clean the stainless steel chamber regularly and avoid leaving water standing for long periods.

A gravity water filter system lets water pass from the upper chamber through the filter elements into the lower chamber without electricity or water pressure. The GF-S001A-1 uses coconut shell carbon block filtration to help reduce chlorine, sand, rust, odors, sediment, and large particles.

Each GF-S001A-1 black purification element is recommended for replacement every 3,000 gallons. Actual service life may vary depending on water quality and usage.

No. Compatible gravity water filter systems work without electricity or water pressure. Water moves through the filter elements by gravity, making them suitable for countertop use.

The GF-S001A-1 filter elements are tested and verified by independent laboratory testing to reduce contaminants such as chlorine, sand, rust, odors, sediment, and large particles, helping improve water taste.

The product information lists reduction of chlorine, sand, rust, odors, sediment, and large particles. It does not state bacteria or virus removal, so it should not be relied on for microbiological purification unless the water source has already been treated or confirmed safe.
