60 PSI is the maximum amount of pressure a Berkey Shower Filter™ can withstand.
The Super Sterasyl™ shell is primarily diatomaceous earth. The Granulated Activated Carbon (GAC) is actually made from carbonized coconut shell. Trace amounts of silver are included to prevent mitosis.
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.
Berkey PF-2™ Elements are designed for use in conjunction with Black Berkey® Purification 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 solution at a […]
The capacity of the Sport Berkey® is 22 oz. and the bottle will efficiently filter 160 refills of raw untreated water and 640 refills of municipally treated water. Always use the cleanest source water possible as the dirtier the water, the quicker the filter element will become clogged.
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® Purification Elements is 11mm.
Each set of four PF-4™ filters is will last for 1,000 gallons or six months, whichever comes first. The reason for the six-month limitation is that the carbon within the PF-4™ filters extracts contaminates that can be nutrients on which bacteria can grow. If the filters are used longer than six months, “grow-through” can occur.
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 […]
