Waterdrop NSF/ANSI 42&372 Certified Water Filter, Replacement for Berkey® BB9-2® Black Filters, ProOne® or Alexapure® Gravity Water Filter System and Waterdrop King Tank Series, (Pack of 2)

Customers find the water filter easy to install and use, and appreciate that it works at half the cost of brand-name alternatives. However, the filter's performance receives mixed feedback - while some say it works fantastically, others report it doesn't properly filter water. Moreover, customers disagree on the water taste, with some saying it tastes good while others mention plastic residue. Additionally, the filter's durability is concerning, with reports of filters breaking in half and separating from their bases.
