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.
Yes, both bottles function identically; the only difference is the generic version has no silk-screening on the exterior of the bottle. The generic versions of the Sport Berkey® filters have been designed for missionaries and relief organizations, where it is critical to keep costs to a minimum.
Unfortunately the Sport Berkey® filter is not cleanable. Replacement filters however, are available. To view information about replacement filters or place an order click here.
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 […]
I noticed that the PF-4™ elements also remove MTBE and heavy metals. Should I use these with my Black Berkey® Purification Elements?
No, the PF2™ is used in conjunction with the Black Berkey® purification elements and the PF-4™ elements are used in conjunction with the ceramic filters. The Black Berkey® Purification Elements remove MTBE and reduce heavy metals whereas the ceramic filters do not therefore; we incorporated MTBE and heavy metals reduction capabilities into the PF-4™ elements.
That is correct, high or low PH impedes the ability of the media to remove fluoride. For maximum removal efficiency, maintain the water being treated between a PH level above 5 and below 7.
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.
I installed my Berkey PF-2™ Elements but my water is a bit cloudy and why does it have a funny taste?
The odd taste is from process dust that may not have been washed free from the filter elements during the priming process. Please remove the PF-2™ elements and re-prime them for 60 seconds on both ends. It may be necessary to repeat the priming process up to ten times to expel all the residual process […]
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.
How do I know when 1,000 gallons has been filtered and when its time to replace the Berkey PF-2™ Elements?
The best way to gauge when to replace the Berkey PF-2™ Elements is to do the following: 1) Keep a track of how many times per week you need to refill your system.2) Then multiply that figure times the capacity in gallons of your particular system (for example the Berkey light™ system is 2.75 gallons) […]
