If NMCL’s recent test results show that the Black Berkey® Purification Elements reduce Fluoride, then why do I need the Berkey PF-2™ Post Filter Elements?

NMCL’s most recent laboratory testing indicates that the Black Berkey® Purification Elements will initially reduce Fluoride up to 99.9%. Typically, carbon-based elements that reduce Fluoride begin to lose that ability rather quickly. This may be the case with Black Berkey® Elements as their efficiency at removing Fluoride likely plays out long before the 3,000-gallon life […]

If Arsenic is removed using Black Berkey® Purification Elements then what is the need for Berkey PF-2™ Elements?

NMCL’s most recent laboratory testing indicates that the Black Berkey® Purification Elements reduce Arsenic up to 99.9%. Typically carbon based elements that reduce Arsenic begin to lose that ability rather quickly. This is likely the case with Black Berkey® Elements, which means that their efficiency at removing Arsenic likely plays out long before the 3,000-gallon […]
