Black carbon filter elements sit in the upper chamber of a compatible gravity-fed system. As water moves by gravity from the upper to the lower chamber, it passes through the dense carbon media, which adsorbs contaminants while allowing clean filtered water to collect below. The reinforced Stem Saver design adds durability during routine handling and cleaning.

BOROUX Foundation™ Black Filters are gravity-fed replacement filter elements designed to give you up to 12 months of clean drinking water per pair. Compatible with popular gravity-fed filtration systems, including Big Berkey-style housings.
