Berkey PF-2 elements

  • PF-2 fluoride and arsenic reduction elements are designed for use in-line with Black Berkey water purification elements to adsorb the following unwanted elements found in drinking water:  Fluoride, (Sodium Fluoride, Sodium Fluorosilicate, Fluorosilicic Acid, and Hydrofluorosilic Acid) >99.75% reduction, Arsenic V and pre-oxidized Arsenic III, and other residual heavy metal ions.
  • Element lifespan:  Each set of two PF-2 elements must be replaced after 3,785 liters (1,000 gallons) or 1 year, whichever comes first.  If filtering 10 liters per day, this is about 1 year they will last.  Make a note on your calendar when it’s time to replace them.
  • PF-2’s thread onto the ends of the Black Berkey elements (work inline), see 2nd photo above.
  • Number of PF-2s in the bottom chamber must match the number of Black Berkey Purification Elements in the top chamber; for example, 4 Black Berkey Purification elements would require 4 PF-2 Filters.
  • Made from safe, non-leaching Polypropolene #5 that is BPA-free.


  • NOTE:  
  • PF-2 filter elements reduce your units flow rate by 15-20%.
  • For maximum removal efficiency, maintain the water being treated between a PH level above  5 and below 7. Actual capacity is dependent on the level of contamination of arsenic, fluoride and other competing heavy metal ions. Unusually high levels of these contaminants may reduce the capacity and efficiency of these elements.
  • Storing your elements after usage:  The Berkey PF-2™ elements can be stored in a refrigerator for up to one month.  To do this, remove the filters from the system, place them into a sealable sandwich bag or container and place the filters in the refrigerator.  If it’s longer than one month they must be discarded.  If you do store them in a refrigerator, we recommend re-purging the Berkey PF-2™ post filter elements, for 1 minute each in both directions, before using them again.  Do not freeze.  The Berkey PF-2™ elements should not be allowed to air dry as this could allow some bacteria growth in the media to occur.

    I was looking at several sites for these water filters. Some sites had fake numbers when I tried calling to verify them. This one had a voice mail and Scott called me back within a few minutes. My filters came the next day!
    I will definitely order from here again. Thanks Scott!

    I bought the stones about 8 months after using my Big Berkey. They give quite an unusual taste to the water at first but it dissipates after about one month. I use only 2 charcoal and flouride filters but am wondering if you are supposed to use the total number of 4 slots?

      Hi Sue! Thanks for your comment and question, I am here to help. You can use either 2 Black Elements combined with 2 PF2s, or 4 of each. Up to you! Using 4 of each will simply make it twice as fast.

    I’m glad you decided to start your business. Buying direct from Berkey would have cost more in shipping & customs than purchasing from you. I wish you all the best with your business and will be sure to refer my friends to you if they want one of their own (I already have one friend contemplating ordering one and my three housemates are all grateful that I bought it).

    I couldn’t be happier. My pineal gland is already clearing up some. I’m experiencing full color dreams and I haven’t had them for the better part of 40 years. We are 92%+ water so it’s no wonder people are sick in North America. The taste (or lack of it I should say) is awesome. Just like the pure spring water my grandfather and I would stop and drink when going up to the camp when I was 9 years old. I’m hooked on Berky’s for life now!

    Thanx again for bringing this to us!

    We bought the Berkey PF-2 fluoride filters along with our Big Berkey in November.
    Removing fluoride was very important on my list, having learnt of its toxic effects on the body.
    Installation was simple and we’re glad we can now drink pure, safe water without anymore dangerous fluoride in it.
    Great product.

    I’ve been using Berkey Light for a couple of years now. the water just tastes way better without fluoride!!! Scott is the best guy to deal with for all the Berkey products in Canada!

  7. Jennifer

    I have an illness and have been advised to avoid fluoride. I bought the Berkey because of these filters. In the few short months I feel so much better and my test results are looking good! So happy!

  8. Sabrina

    Easy to install and worth every penny for the peace of mind that comes from knowing my water is free from fluoride, arsenic, etc. Until the city of Winnipeg stops adding toxic chemicals to our water, I’ll be drinking as much as I can from my Berkey with the fluoride filters!

  9. Artur Jany

    We purchased these fluoride filter additions for our Berkey water filter and have
    been very satisfied with them. We wanted to make sure that our drinking
    water doesn’t contain fluoride and this has done the job very well. They were easy
    to install, and easy to clean. I do wish they lasted a little longer, but then we drink a lot
    of water on a daily basis, and they are inexpensive to replace when a new one is needed.
    Satisfied with this product.

    We ordered the Flouride and Arsenic Filters for our Crown Berkey which is at our office of 20 people, we weren’t as concerned about the Flouride in our water since that has never been found but at one time a water tower and pumping station which we receive water from did have amounts of arsenic found within that water supply, In order to be certain and to build confidence within our water drinking staff we opted for this filter to be on the safe side, after priming it properly and thoroughly rinsing the filter we are happy to have installed it in our Berkey.

    An excellent addition to the Berkey water system. With concerns about fluoride and other chemicals in water these filters are fantastic and you quite a great job.

    I purchased my Berkey Water Filter last year and a good friend in the alternative health field reminded me to buy a Fluoride filter. Scott was very helpful in getting a pair to me and I’m very happy to have them. I recommend them highly, especially if you live in a city or in an area where the water supply is questionable. It would be ideal and lovely to be living in a time when we didn’t have to be so concerned about our water but until we can make this possible again, let’s be grateful for Berkey and Conscious Water! Thanks Scott for always prompt service and replies!

    We ordered 2 of these to go in our Big Berkey. They are essential for us, as we are filtering Los Angeles city water, and no other filter we could find can eliminate the flouride – a very dangerous element, when ingested long term. They may decrease the flow a bit, but it doesn’t matter to us since we are only 2 people using it, we just fill up the night before, and by morning there is plenty of pure water! These PF-2s are highly recommended. Also I would use them for filtering well water, which can often contain a lot of arsenic, also not good when ingested long term. Thank you Conscious Water!

    One of the main reasons we wanted a filter was to remove fluoride, and this does the trick well! Definitely worth it…fluoride is implicated in many health issues, and we feel confident that using these filters have helped us stay well! 🙂

  15. Stefan Choptiany (verified owner)

    This is a great product and one of the few techniques aside from RO that will get the fluoride out of your water. Be sure to follow conscious water’s instructions on flushing them, because it can take a while to fully flush and prime them. There are also many other chemicals that these filter will help remove, aside from fluoride.
