Are the Black Berkey® Elements NSF certified?
NSF certifications are not required but rather optional. In our opinion, NSF certifications are limited in their application with respect to our gravity fed filtration elements. NSF Standard 42 (aesthetic effects) and Standard 53 (health effects) would specifically apply to our filtration elements. NSF Standard 42 covers systems “designed to reduce specific aesthetic or non-health-related […]
What is the thread size for the Black Berkey® Element’s Stem?
The thread size on the stem of the Black Berkey® Elements is 11 mm. The outer diameter is about 3/8 of an inch and the inner is about 2/8 of an inch.
What are the washers for the Black Berkey® Elements made out of?
The washers are made of food grade Neoprene Rubber. However, keep in mind that the washers never touch the filtered water.
Will the Black Berkey® Elements remove kerosene?
Petroleum based products are some of the easiest to remove from water. The Black Berkey® Elements have been tested to reduce the following petroleum contaminants up to 99.9%: Gasoline Diesel Crude Oil Kerosene Mineral Spirits Refine Oil For complete lab results on the Black Berkey® Elements, click here However, please keep in mind that it […]
Do the Black Berkey® Elements remove lithium?
It is our understanding that Lithium is an alkali metal, found in Group 1 of the Periodic Table. Lithium can be very reactive when exposed to water. Current testing of this potential contaminant has not been conducted, at this time.
If Arsenic is removed using Black Berkey® Elements then what is the need for Berkey PF-2™ Elements?
NMCL’s most recent laboratory testing indicates that the Black Berkey® 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 life […]
What happens if I use my Black Berkey® Elements after 3,000 gallons?
We determine the typical lifespan of the Black Berkey® Elements by their ability to reduce heavy metals. The breakthrough of heavy minerals can occur at about 3,000 gallons. Heavy metals can leach through beyond 3,000 gallons. However, the elements can be used beyond that point because other reductions continue well beyond 3,000 gallons.
Black Berkey® Elements Assembly
The Black Berkey® Elements are the leader of gravity-fed water filtration. We recommend replacing Black Berkey® Elements every 3,000 gallons (6,000 per set of 2 elements). Elements may require replacement sooner based upon the quality of influent water. The Black Berkey® Elements are sold as a set of two and can be used to upgrade […]
