NSF/ANSI 42 Certified Black Purification Elements, for BB9-2® Water Filters Replacement, Compatible with Berkey Gravity Filtration System, Replacement for Berkey Black Filter, Pack of 2

Customers find the water filter to be of good quality, matching Berkey standards, and appreciate its easy installation and perfect fit, particularly noting it works well with 1.5-gallon Berkey systems. Moreover, they consider it a great value option. However, the filter's performance receives mixed feedback - while some say it works well, others report it stops working after 30 gallons. Additionally, customers disagree on the water's taste, with some saying it tastes better while others find it awful. The filtering speed and clarity also receive mixed reviews, with some reporting fast filtration and clear water, while others experience slow flow and cloudy water.
