  1. Dot Forscht

    No five stars because I primed these much more thoroughly than required in the instructions, yet when I installed them the water was still cloudy and some grey residue was in the bottom of my Big Berkey. I had to refill and empty three more times on top of the first recommended time, and in addition to extra rinsing of the elements themselves. BUT once that was done, they’re working great and the water tastes great.

  2. Aaron Kesseler

    After several weeks, I noticed white particles in the lower chamber of the Big Berkey, which I feared was the the PF-2 filters failing somehow and releasing aluminum oxide into the water. Because I am pregnant and drink this water, and I also give it to my toddler and husband, in a panic I ordered an aluminum test for the water (thank you, Amazon!) and found that the aluminum levels exceed EPA and WHO standards! For comparison, I tested our tap water and it had a reading of essentially zero. I should also note that I sufficiently primed the filters upon set-up. Shame on Berkey for selling a dangerous product! I have since contacted the company, which responded initially, and now has fallen silent. I’m not sure how far I can take the issue, but I will certainly try

    I am on my second set of filters. These are great! If you are impatient and do not flush them long enough you will have an oily residue in the water and have to keep dumping batches until that clears, which is what I did the first time I got these. This last time I really took some time to flush the filters and I didn’t have that problem. No matter what, these give you the best tasting water in my opinion. I think they are a great value and highly recommend them.

    State Environmental Laboratory Results
    A sample of the Berkey water was submitted to my State Env. Lab. The results showed a value or 0.40 MG/L Units. We use our City water to fill the Big Berkey.
    Our City water’s fluoride level is 0.87 MG/L to 0.96 MG/L.
    Hope this helps someone to evaluate their decision about choosing the best water system

  5. Clara Calmelat

    I got my Berkey because my village adds fluoride to the water. Removing it myself seems to be the next best thing since I have not been successful in getting them to stop. I looked into several water filter options and this was the most affordable and realistic for me.

  6. Kristy Archambault

    They are a b**** to prime, but I’m so glad to have them. Flouride and whatever other chemicals in the tap are no good for you or your kids! Anyway, just prepare to prime them under high-pressure water flow for a good long while. Like maybe even up to 20 min.

  7. Carl Bishop

    I can not even smell tap water after using a Berkey for over a year now. I feel generally healthier and use Berkey water for drinking, making tea/coffee and filling the water bladder up before hikes. Please note, I incorrectly ordered the PF-4 size now knowing they come in different sizes so make sure you order the correct size (though I have to say, Amazon’s return process was ABSOLUTELY INCREDIBLE with no hassles). There is one thing I’m curious about… both this order (and the incorrect order) had only ONE of the gray washers in the package. It seems like there should have been two since you are replacing both filters.

  8. Denisa Goad

    For starters people have been complaining about the white film in the water, which is undeniably there when you first install them (even after priming). I have been using these for about two years and it doesn’t matter how much you prime them, this will always happen. I have a Royal Berkey and I have to run 4 full filters of water through these before it goes away. My town as high levels of fluoride in the water and so I use these filters to lower the level for my children’s drinking water so they don’t get discolored teeth from the drinking water. It occurred to me that maybe I should be changing them more frequently because of the high level of fluoride and the customer service person from Berkey told me that that was NOT the case and the level of fluoride did not matter. This didn’t make sense to me so I got the water tested: once from the tap, once from the filters that were 5 months old (the customer service person told me I should change them after 8 months BTW because of our level of usage) and lastly from a set of new filters that had been cleared of their white gunk. The results were that our tap water was 2.5 (it should be under 2 to prevent damage to children’s adult teeth as they are growing), the 5 month old filters had only reduced it to a 2.2, and the new filters reduced it to a 0.5. From these results it seems obvious that the level of fluoride in the water affects how long the filters will last.

    I’m going on 2nd year ordering these filters to deal with the filtration of my public water in my home. I’m happy with the water quality so far. My whole family loves drinking our purified water.

    I personally add Pink Himalayan Salt to my filtered water as this raised the pH of the water and provides over 84 trace minerals our bodies need. I don’t need soda, coffee or sports drinks. This is perfection in simplicity.

    I must say that I am pleased with the shipping, quality and durability of ALL my Berkey products that I’ve purchased. I’m a Berkey customer for life.

  10. Mer Hess

    Love these filters! One thing that I will give a heads up on is that you need to prime them really really (really) well or else your water will have a slightly off taste for a while until all the loose powder is worked through. Once it is primed well, the filters do an excellent job of taking the fluoride out. I have not done any formal testing of our filtered water other than with my own taste buds but Im really sensitive to tastes and pick up on nothing in the filtered water now.

  11. Shiaoting Jing

    We have been using our Berkey system for over a year now (it replaced the PUR). This is the BEST product out there. It is cost-effective and reduces chemicals better than any other. We recently added the fluoride filters and wish we had done this sooner. Ingested fluoride is a neuro-toxin and should not be in our water supply.

  12. Nathan Yandle

    We’ve had our Berkey for over a year. The fluoride filters are the main reason we purchased a Berkey. They are only good for six months. I tested my water twice to verify this. Our water comes from a well and is naturally fluoridated at about .9 ppm (parts per million). I tested a filter by purchasing a kit through 3M (about $20) after seven months of use and the water tested at 0.79 ppm. I replaced the filter and tested after about a month and the water came back to 0.06 ppm. Hardly any fluoride! I am curious to test my water again at the five month mark but not sure I want to spend an additional $20. I think I will just stick to the manufacturer’s recommendation of changing out ever six months. Overall, this is the way to go if you want to remove fluoride from your drinking water.

    After seeing multiple reviews state that their water tested so high for fluoride I would be curious to ask when they tested their water. They might have misunderstood the directions and be using their filters after six months. The black filters can be used indefinitely, but the fluoride filters lose effectiveness after six months of use. Another possibility is the ph of their tap water. I think the ph of your water can affect the effectiveness. I am not a scientist but have read that the filters work better with slightly acidic water (pH range of 5.5 – 6.5 and generally don’t work well if the water is neutral (pH = 7) or more alkaline (higher pH). So if you want to be sure that your filter will work to filter out fluoride you could test the ph of your tap water first.

    This consumable will normally last about 1 year of regular use. Tells you how much flouride there is in our water to begin with

    In Singapore where the flouride content is high, this is an absolute addition to the Berkey black filters we use. The water comes out tasting soft instead of hard (is there even such a term).

    We don’t even need to boil our water everyday. The result, just good, quick and clean tasting water for the family everyday.

    P.S. Also one of the filters was punctured inside. Amazon sent a replacement with minimum hassle, which arrived very quickly

  14. Henri Augustus

    These filter quickly in our Imperial Berkey. We use 4 black filters and 4 PF2s. I think that there is a very noticeable taste difference with these over just using the black filters. Our water doesn’t taste hard or metallic. We fill the 4+ gallon Berkey at least 3 times daily so we’ll see how long they last…so far so good.

    Berkey “fluoride filters” for the black to go with the Black Berkey, work as advertised. They need priming before use to flush out the powder residue in the filter. I have found this takes many flushes before the water runs clear, so I leave them by the sink for a few days and flush them every time I wash something. And finally a word of warning don’t buy the PF-4 filters by mistake, they only work with the ceramic Berkey filters (yes I did this – but only once :-).
