Waterdrop Replacement Black Elements for Waterdrop King Tank Systems and Other Gravity-fed Filtration Systems

Transforming gravity-fed storage into clean, great-tasting drinking water, the Waterdrop WD-BB9 black elements use natural coconut shell activated carbon. Each element filters up to 6,000 gallons and fits Berkey BB9-2 and other compatible gravity systems.

Key Features

• Coconut Shell Activated Carbon: Reduces chlorine, sediment, sand, rust, odor, and large particles while improving the taste of your water.
• 6,000-Gallon Capacity: Each filter handles up to 6,000 gallons, providing long-lasting value for home and emergency use.
• BPA-Free Housing: The filter housing is made from BPA-free materials for extra safe drinking water.
• Tool-Free Installation: Designed to fit the original brand without leaking, with no additional tools required.

These elements replace the Berkey BB9-2 black purification element and fit popular gravity-fed systems from other brands. Compatibility is listed in the table below.

If flow seems slow, the cause is usually air trapped in the micro pores of a new element. Prime the filter as the owner’s manual directs to purge the air and restore normal flow.

Avoid scrubbing the elements. Unnecessary cleaning can introduce bacteria and hinder performance, so replace them on schedule instead.
