The Black Berkey purification elements are the leader in water purification, and have been tested by State & EPA accredited laboratories to exceed EPA 7 ANSI / NSF (Std. 53) protocol. (Scroll Down For Contaminant Removal List) Lab Test Results Found Here
Black Berkey Purification Elements are more powerful than any other gravity filter element currently available. In fact, the Black Berkey purification elements have been tested with more than 10,000 times the concentration of pathogens per liter than is required by standard test protocol. This concentration of pathogens is so great that the post filtered water should be expected to contain 100,000 or more pathogens per liter (99.99% reduction - the requirement for pathogenic removal). Incredibly the purification elements removed 100%. Absolutely no pathogens were cultured from the effluent or were able to be detected, even under an electron microscope, setting a new standard in water purification.
No need for expensive disposable filters that need replcaement every couple months. Black Berkey purification elements are re-cleanable during their 6000 gallon lifetime. When the flow rate decreases simply brush the Black Berkey purification elements with a ScotchBrite pad under running water, reinstall and your system is again ready to purify water. Each durable and efficient purification element will last for up to 3,000 gallons (6,000 gallons per set of two) and provide years of efficient water purification. What's more unique is that the Black Berkey purification elements are self-sterilizing.
Black Berkey purification elements are so powerful, they can remove food coloring from water without removing the beneficial minerals your body needs. Virtually no other filtration element can duplicate this performance. Perform this test on your black berkey filters at any time to ensure your filters are operating to design specifications.

Note: Black Berkey purifying elements are upper chamber elements. They do not work simultaneously with upper chamber Ceramic Super Sterasyl elements. Only one technology is designed to operate in the upper chamber at a time. These filters will work in the British Berkefeld systems and other many other gravity water filter systems on the market. They can also be chosen as a upgraded filter to replace the ceramics.
Black Berkey purification elements have a 2 year prorated warranty calculated in 6 months intervals. The manufacturer will replace or repair any product that it deems is not properly functioning during the stated warranty period.
BigBerkeyWaterFilters is always at your service to assist you with any warranty claims, send you replacement hardware free of charge if needed, or provide system maintenance support during the life of ownership.
Note: Some Black Berkey filters may come with a small dimple or chip off of the top filter. This does not affect the performance, filtration efficiency, or life of the filter in any way. As a result, it would not be covered under the warranty as it is not considered defective. This can be verified by performing a red food coloring test on the filters to test them.

You would multiply the number of times out filter your system per day "times" the size of your system "times" the number of days you've used it. For example, if you use a Big Berkey system 1 year: 365 days x 1 time per day x 2.1 gallons (Big Berkey size) = 767 Gallons used.
Hope this helps!
Thanks, and I look forward to hearing what you have to say.
Without EPA certified lab test results for this toxin, we cannot state what the Microcystin removal rate will be by the berkey. Currently, the EPA does not have guidelines and testing parameters for this toxin, thus the labs are not certified for consumer filter system testing. You can do a google on water filters and microcystin and you will see papers on the subject. For more and the latest on Berkey removal of Microcystin can be found in this blog post: http://www.bigberkeywaterfilters.com/blog/microcystin/algae-bloom-and-microcystin-removal-berkey-faq
The final PH will be dependent on the source water PH. The berkey filters do not add anything to the water to increase the PH, but they remove acidic contaminants that can ultimately result in a PH increase. Most customers see a rise, but there is no guarantee.
No, the black berkeys do not contain any alumina. As for their process of operation, from the FAQ "Without getting too complex, several methodologies are utilized by the Black Berkey purification elements. The elements are composed of a formulation of more than a half dozen different media types constructed into a very fine matrix creating millions of micro-fine pores. The pores are so small that pathogenic bacteria, cysts, parasites, sediment and sedimentary minerals are not able to pass through them. The media formulation both "absorbs" some contaminates and "adsorbs" other contaminates. Next, heavy metals ions (mineral molecules) are extracted through an Ion exchange process where they are essentially electrically bonded to the media. Finally, our filter elements are designed such that each water molecule can take several minutes to pass through the filter elements whereas these molecules passing through other filtration systems pass through those filters in literally microseconds. The longer the water molecules are in contact with any media, the greater the removal of the various contaminates."
Ye, they would still be functioning as designed. The 6000 gallon mark per set of 2 is an approximation simply because all water sources are different. Some having higher levels of contaminants, and others having lower levels. We would just caveat and say that we'd consider replacing them soon as we know from experience that the filters start to reach full saturation around this 6000 gallon mark per set of 2.

Also, the PH will be dependent on the source water PH. The berkey filters do not add anything to the water to increase the PH, they only remove acidic components that can result in a PH increase. With that being said, we cannot provide a estimated PH number for your end result filtered water. Most customers see a rise, but there is no guarantee.
Yes, this can happen given it's a moist surface. However, the inside of the filters is self sterilizing, so algae cannot grow down into the filter and disrupt that process. You can just scrub this algae off to allow water access to those filter pores, and you're good to go.
This article will provide some good information for cleaning your filters.
The filters would remove the bacteria and any chlorine just fine, so this would not be a concern. The question would be if there were other soaps or chemicals that were in the water that might not be able to be removed. As you know, the Black Berkeys will remove most contaminants, but the only way to be 100% sure is know exactly what's in that hot tub water, and compare it against what the berkeys will remove.
Fluoride does not have a taste to it, and the black berkeys do not remove fluoride. You may be thinking of chlorine, which the black berkeys do remove, and does have a noticeable taste. We would recommend checking your connections and seeing where this leak may be occurring. It would typically be a loose connection and just a wing nut that needs fastening. If it's not a connection issue, and you think it may be coming through the black berkey itself, then you would want to follow the procedure for performing a red food coloring test on the filters (shown here), to isolate the filter that may be problematic or exhausted.
I'm starting to see an indent on the filter. Over time, how will I know when I've removed enough that replacement is in order?
The vegetable peeler should only be used as a last resort, but if you're current situation requires this, then you would want to do periodic red food coloring test on the filters to make sure the integrity of the filter has not been compromised and they are still performing effectively. Explained in detail here:
The Black Berkey filters should remove the cyanobactaeria due to the fact that they remove other bacteria to 99.9999%, in addition to smaller sized viruses from the water. The microcystin toxin released from this bacteria has not been tested however. We do know that studies of filters of similar ingredients were able to have an affect removing the microcystin, but this is the extent of what we can state without specific test results.
