  • Elements come with a 2-year, pro-rated warranty

PF-2 Fluoride and Arsenic Reduction Filters

The PF-2 reduction elements screw onto the bottom of the Black Berkey water purification elements and work in conjunction to adsorb the following unwanted elements found in drinking water.

• Fluoride
• Arsenic V and pre-oxidized Arsenic III
• Other residual heavy metal ions


FLUORIDE: Testing for fluoride was based on 20-30ppm of the ion in the influent aqueous solution at a flow rate of no more than 3 gpm (11 lpm) per cubic foot of media. Results of < 1ppm of the fluoride ion in the effluent were typical for the media (>95% reduction). Under optimum conditions, effluent concentrations of less than 50 ppb were readily achieved (>99.75% reduction).

ARSENIC: This product uniquely targets the entire family of arsenic oxide anions as well as the arsenic cations.

REPLACEMENT:  Under normal circumstances, a set of 2 fluoride filters should be replaced every 1000 gallons

    Happy customer for 10 years :)

    Posted by John on 17th Oct 2019

    I got a Big Berkey ten years ago after reading the water report for my local water. With our water usage, we replace the filters once a year, and it's been a great decision for us! The water is not only clean but it tastes better. There was one time that the filters didn't work properly, and they sent a replacement right away, no problem! I recommend them very highly.

    Calcium is reduced to 22 ppm.

    Posted by Kirk on 7th May 2018

    No more calcium deposits when boiling water that was filtered. I have an Osmosis filteration system first and this final product reduces the calcium from 448 ppm to 22 ppm after it comes out of the Berkey black carbon filter. Perfect taste!

    Wouldn't Buy Any Other Filter Brand!

    Posted by Esther II on 16th Dec 2016

    I have used the Berkey water filtering system for 2+ years and will not purchase any other brand. The water tastes so fresh, cost is very reasonable. I love seeing the clearness of my water in clear glass containers. My daughter had purchased a different system two years ago that cost $300. They then switched to a very expensive reverse/osmosis system. The whole family and pets were frequently getting ill. After hearing me praising the Berkey system she switched to Berkey and the family and pets have remained healthy.

    Excellent water filter system.

    Posted by Herb LeCompte on 4th Feb 2015

    We recently started using the fluoride filters with our black filters for our Berkey water treatment system. The water is so clean and tastes so much better. When we travel we take our system with us. We refuse to drink water from the tap or bottle without filtering it through our filters. We highly recommend this system to protect your family.

    I was absolutely delighted to find that the Berky water filters fit the Katadyne gravity water drainage system perfectly. Prepping the carbon filters was a bit of a challenge, and messy. I called customer service for help and got a few pointers. In contrast the fluoride filters were very easy to prep. The water tastes wonderful.

    Excellent filters

    Posted by DS on 5th Feb 2014

    Having owned the Berkey system for more than 15 years, I have always bee satisfied with its' performance. My recent purchase of replacement elements and post filters caused a minor concern when the post filters began with a trickle, rather a constant drip. I feared something was wrong. I checked the filters using the red food color test, but all was well. Thumbs up for Berkey! DS, NH

    purity you can trust

    We use the Berkey filters for all drinking and coffee and tea making. I usually change the filters after 6 mos to 1 year. We like it better than bottled because we are not filling the landfills with plastic.
