Petroleum based products are some of the easiest to remove from water. The Black Berkey® Purification Elements have been tested to remove 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®Purification Elements, click here However, please keep in mind that it […]
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.
When water is filtered through our system, the Black Berkey® Purification Elements increase the PH level of the water. This is healthful because pathogenic bacteria and viruses thrive in acidic environments and have difficulty surviving in alkaline environments. An environment with more alkalinity does have a higher PH level. The PH level will depend on various […]
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 […]
We determine the typical lifespan of the Black Berkey®Purification 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.
The Black Berkey® Purification Elements are the leader of gravity-fed water purifiers. Each element is designed to purify approximately 3,000 gallons of water before needing to be replaced; 2 elements in a Berkey® system will purify approximately 6,000 gallons of water before replacement is recommended. The Black Berkey® Purification Elements are sold as a set of two and can be […]
