Our unfiltered tap water was generally acceptable by the lab with the following notable exceptions:
1. Arsenic: 2.5 parts per billion (ppb) - lab considered this reason for "caution"
2. Uranium 238: 3.1 ppb - also "caution"
3. Aluminum: 94 ppb - caution
4. Fluoride: 0.8 parts per million (ppm) - EPA has not established levels for this category
Here are our results with the Big Berkey (using 2 black filters and 2 fluoride/arsenic filters):
1. Arsenic: less than 1 ppb - lab considers "acceptable"
2. Uranium 238: less than 1 ppb - acceptable
3. Aluminum: 19 ppb - acceptable
4. Fluoride: 0.4 ppm (I wonder if we used 4 fluoride filters instead of 2 if the fluoride would be removed completely)
Items of note, the lab that tested the water is a professional lab (not a home kit) and there are three levels of interpretation: acceptable (safe), caution (consider filtering) and unacceptable (contact municipality and consider alternative sources). The lab uses ICP-MS method to test the water.
Hope this helps. Disclaimer: I have no relationship to the company....I just wanted to know whether or not the filters work!
Cons: If you're putting this together for the first time remember to prime your flouride filters. I recommend you repeat the priming process 3 or 4 times! Don't use what they suggest (30-60 second intervals). To remove the bitter taste I had to disassemble my unit and prime each filter 4 times for 90 seconds on each end. That, in theory, is a total of 8 priming attempts! As you switch from end to end you will see a glimpse of milky water. Repeat until you do not and don't skimp on the duration. I still taste an extremely minor bitter hue to the water, but again it's not noticeable. If you want to save yourself some time and frustration, bite the bullet and prime these filters BEFORE HAND. The Black Berkey filters, however, prime wonderfully according to the instructions.
NOW ONTO THE SPIGOT. I came home to a soaked floor three or four times. The beveled washer will not sit flush as easily as they depict. Remember to visually line up the washer so that you can see no gaps when tightening it. I also recommened you tighten it a quarter turn as they say, but tighten the nut inside the unit as much as you can. I got fed up on the last attempt. I woke up to a wet floor, grabbed gloves, and fiddled with the nut while water was still in it. This way I could MAKE SURE it didn't leak. Long story short you need to overtighten the internal nut in order for it to not leak. If you don't get lucky lining it up then you will have water everywhere.
The Berkey System caught my attention after reading positive reviews, watching related videos on youtube and doing a bit of research. In the end I can say that I am 100% satisfied with this system.
I initially took my time setting up the system as to assure it was done properly. I read stories about people ruining their filters by improperly installing them (ie., screwing the filter on too tight). Also, prior to using the filters they must be "primed" by flushing them with water. The filters must be flushed in the correct direction and doing so takes a a little bit of skill. I flushed the PF-2 filters for 20 seconds according to the Berkey Manual Instructions, however the factory dust that discolors the water with a white foggyness did not flush out in just 20 seconds. In fact, it took me about 90 seconds to completely flush them out.
In anycase, after they were primed, I screwed everything to the canister very carefully according to the instructions. I then filled the canister up with 2 1/2 gallons of water and then discarded the first filtered batch. I filled up the canister again for a second batch and when that completed I tasted the water.... Wow! the water tasted great. I filled up a glass of Berkey Filtered water and another glass of regular tap water and compared side by side. I could not notice any difference in the look of the water. However, the difference in smell was significant. The Berkey filtered water smelled like water should; clear, crisp and odor free. The tap water (i kid you not) in comparison smelled a bit like sewage.Read more ›
