60 PSI is the maximum amount of pressure a Berkey Shower Filter™ can withstand.
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.
Berkey PF-2™ Elements are designed for use in conjunction with Black Berkey® Elements to adsorb the following unwanted contaminants found in drinking water: • Fluoride • Arsenic V and pre-oxidized Arsenic III • Other residual heavy metal ions TECHNICAL INFORMATION: FLUORIDE: Testing for fluoride was based on 20-30ppm of the ion in the influent aqueous […]
The capacity of the Sport Berkey® is 22 oz. We recommend replacing the filter after 640 refills of municipal water. Filter may require replacement sooner based upon the quality of influent water.
I understand that the media used within the Berkey PF-2™ elements is activated alumina. Is that the same thing as aluminum?
Our PF-2 filters reduce fluoride and arsenic in your water using the media aluminum oxide (aka activated alumina). As a consumer, it’s important to know that pure aluminum and aluminum oxide have vastly different characteristics. Pure aluminum is water-soluble, it is highly reactive and it is associated with negative health effects. By contrast aluminum oxide […]
The individual elements are 6” in length and 2.5” in diameter. The side of the Berkey PF-2™ Elements that attaches to the Black Berkey® Elements is 11mm.
Each set of two Berkey PF-2™ Elements will last for approximately 1,000 gallons of water.
In the past the Berkey Light® systems were made of food grade polycarbonate that was approved by the US Food and Drug Administration. Some research suggests that polycarbonates have been known to leach BPA (Bisphenol-A) when either exposed to High Strength Industrial Grade Alkaline Detergents or when they are repeatedly exposed to temperatures in excess of […]
The Sport Berkey® Portable Water Filter is the ideal personal protection traveling companion- featuring the IONIC ADSORPTION MICRO FILTRATION SYSTEM. The theory behind this innovation is simple. The bottle’s filter is designed to extract, remove and/or dramatically reduce a vast array of health-threatening contaminants from freshwater sources and water supplies, including those in foreign countries […]
With respect to the micron rating, NMCL does not use or publish a micron rating for the Black Berkey® Elements for the following reasons: There is much confusion with respect to nominal and absolute micron ratings. An absolute micron rating is one that states the maximum pore size expected within an element. The nominal micron […]
