    • Simply the Best!
Style: Reduction Elements
Supremely reliable and long-lasting. I will change out my Berkey Blacks every 6,000 gallons (or 6 years), and I change out the PF-2's every year. Can't beat it. In Texas we fluoridate our municipal water. These post filters do an excellent job at removing fluoride and it's varying derivatives. Also, due to the agriculture surrounding every municipality, arsenic is a big concern. The PF-2's remove fluoride and any potential arsenic from the water without having to wait 24 hours for water to adequately flow. Previously, I owned Pro-Pur filters. The first Pro-Pur ceramic filters I owned were dual domed and contained a weird filter core. The water took HOURS to filter through. I eventually got the pair working, until 6 months later the core came of the filters and settled in the bottom drinking water tank. I then changed them out for a pair of the newer Pro-Pur G2.0. Worked great but the filtering time for every Pro-Pur filter is AWFUL! I made the change to Berkey and it's been AMAZING! ... show more

you get what you pay for. the only company that has proven filters. so you could go with cheaper options but there is nothing to prove those companies are actually filtering the water. thats why these are so expensive. good quality and durability. waterflow is good. i had someone put lemons in the top of my filter so i had to remove and clean them out which was easy cleaning. ... show more

I am the person that usually gets generic brands for disposable things but I don't compromise when it comes about water quality. These filters are absolutely worth it. I don't own Berkley system though, I got a generic brand off Amazon but use these genuine filters because I am confident my family will get quality water. last a long time. ... show more

    • These are authentic Berkey filters... it's my preference!
Style: Reduction Elements
Authentic Berkey filters. I received these filters a couple days ago and the only issue I encountered was due to operator error. 🤣 I misread the instructions and forgot to remove the black plugs from each end of the first filter. Water sprayed everywhere while I tried to get water to go through a capped filter! One thing I did differently... Instructions say to run water through one end and after the water runs clear, repeat this step on the opposite end of the filter and then you're done prepping the filters. After I ran water through both ends, I went back to the first end and tried it again and it was cloudy again so I ran it some more and then did the same for the other side. I flipped back and forth 3-4 times until I didn't see cloudiness. After I installed the new white filters I noticed a faster drip rate. (I was way overdue for replacing these. ) Tips: 1) Our black Berkey filters aren't due for replacement yet so I didn't not remove them from the upper tank because I didn't want to mess with thread integrity of the plastic screws. Also, there's no need to remove the black filters when swapping out the white filters. 2) Berkey recommends scrubbing the outside of the black filters occasionally to maintain filter life. I've never done this, but using a new kitchen brush and water (no soap!) , I scrubbed the sides of the black filters and then rinsed them and the upper chamber several times. ... show more

    • Works fine despite other recent reviews. Don't let it dry out!
Style: Reduction Elements
I had to replace my barely used PF-2 fluoride filters in my Royal Berkey because I allowed them to dry out completely through a use hiatus. It is frustrating that this particular MAJOR CAVEAT is not mentioned more clearly for the consumers, and I'm sure that many Berkey owners end up resuming the use of the dried out filters unknowingly. I only found out that PF-2 filters MUST be discarded after it's been allowed to dry out after I contacted a Berkey support. On a further web search, if you're not actively using the PF-2 filters, you need to remove them and store it in the refrigerator (not freezer) for only short term to prevent them drying out and to discourage pathogen growth on the media. You must flush them before resuming use before re-install. If PF-2 filters have ever been activated/primed/wet, the clock starts ticking and you must keep the medias wet and replace them after 1 year or 1,000 gallons filtering, whichever comes first. Many Berkey users buy the costly system not only for daily water filtering, but to use for emergency survival backup system, so this is quite disappointing. The filter setup is cumbersome and must be followed very carefully. Because of so many recent negative reviews for Berkey as a whole, I actually ended up trying another water filter instead of buying replacement PF-2 filters. However, that ended up being a failed experiment, so I proceeded to order the replacement PF-2 filters. I purged the fluoride filters for total of 6 minutes each (2 minutes x3 changing the flow direction) instead of the recommended 20 seconds x2 past water running clear (using a strong thumb pressure on top of the faucet against the purging button for complete water seal with water spraying everywhere occasionally!), and made sure to turn the filters exactly 8 full revolutions. There was some resistance to tightening at 6 1/2 revolutions, so I was actually afraid of puncturing the internal filter media screen while following the install instruction for the full 8 turns because the Berkey rep pointed out that's causative to many reported problems. I may have been overzealous in my purging effort, but my PF-2 filtered water tested at 59 ppm for TDS and the water stayed absolutely clear. Without the PF-2 filters installed (double filtered with Filtrete Maximum), the Berkey water tests at 79 ppm. Berkey really should've improved the filter design to make it more fool-proof since its introduction a long years ago. Also, many reports of the main black filter manufacturing defects (forums & reviews) should prompt you to run a red dye (must be non-organic) test as soon as you receive your system so that you may return/exchange a defective element. If the black elements are not functioning properly, it'll drastically shorten the PF-2 filters service duration. When I initially contacted Berkey with my concerns over many of the critical reviews, including one in particular which stated that PF-2 removes flourosilicates only, the Berkey agent disagreed and shared a recent lab result done on 2/18/2018 by an NELAC ISO accredited lab. ---- Accumulated Volume, Influent Water FluorideConcentration in mg/L, Influent Water pH, TDS inmg/L, Effluent Fluoride Concentration in mg/L, Fluoride % Reduction. Start, 3.82, 6.46, 327, 0.10, 97.4 5 gallons, 3.82, 6.46, 327, 0.06, 98.4 25 gallons, 3.75, 6.48, 320, 0.07, 98.1 50 gallons, 3.79, 6.52, 318, 0.07, 98.2 75 gallons, 3.80, 6.51, 310, 0.07, 98.2 100 gallons, 3.80, 6.52, 312, 0.11, 97.1 ---- Your water PH level should be between 5-7 (closer to 5 the better, my PH is near 7), or the efficiency of the media will decline. Berkey also states that the PF-2 media will remove any types of inorganic fluoride salts soluble in water(sodium fluoride, sodicum fluorosilicate & calcium fluoride) along with fluorosilicic acid (aka hydro-fluosilicic acid). It also removes arsenic V and pre-oxidized arsenic III along with other residual heavy metal ions. There are many reviews concerning aluminum detection/suspension, but Berkey uses aluminum oxide (Al2O3) which is a safe non-toxic bio-compatible ceramic (corundum as in rubies and sapphires), different from the toxic aluminum metal. Lab testing can result in a false positive by counting the separated pure aluminum ion from the oxygen component. The use of activated alumina is one of three EPA and WQA recommended methods for removing fluoride, the other two being Bone char carbon (cheaper and not as effective) and reverse osmosis. Appropriated purged, installed, and maintained PF-2 filters most likely will not result in cloudy particulate in filtered water unless due to unexpected manufacturing defect. Be sure to order yours from a trusted reseller source to avoid counterfeit/used filters. The water temperature rises during the activation so you should definitely notice warm cloudy water during the initial filter purging procedure. I am taking a star off for the aforementioned issues and for the persistent deficit in manufacturing design improvement endeavors along with the specific PH requirements. However, I can't find as effective competing gravity-fed system that filters above 97.* % of fluoride short of going full-on reverse osmosis or steam distillation that strip water of beneficial trace minerals unless using re-mineralization for taste and health. I will monitor the TDS level steadily to track the reduction of its efficiency throughout the use duration; after just 20 gallons refill, the TDS went up 10 ppm, so I will reverse-flow flush the PF-2 element continually during monthly chamber maintenance. Berkey water makes the best coffee. ... show more

Due to autoimmune issues I try to avoid tap water with it's chlorine, flouride, etc. I've been buying bottled spring water and have been wanting a Berkey, but didn't know what size to get. With pandemic and the difficulty in finding bottled water I decided it was time to finally make my purchase. They were backordered at Berkey so I was grateful to find a Travel Berkey on Amazon, and then was able to purchase these filters, as well. They arrived several days later. With my faucet having a built in sprayer, it made priming the filters a bit more of a challenge. But I got them primed and installed and am enjoying the clean taste and peace of mind that my filtered Berkey water provides. ... show more
