Water pitcher lab testing results. I feel this information should be made freely accessible, not having to subscribe or pay or anything else. It benefits everyone to know which ones work the best and information that helps someone to lead a better life, should be free, in my own opinion. I apologize to anyone that has taken offense to my doing this but, life shouldn't be about money or making a profit in any other form. Life should simply be about people helping people to live a better life.
Big Berkey -
Big Berkey was by far the best-performing gravity water filter tested, achieving near-total removal of all toxic elements when used with the attached arsenic / fluoride filters (which attach underneath the black ceramic filters).
Product assembly was straightforward and simple, and all the parts in the unit worked reliably.
Reduction of elements by Big Berkey:
Zen Water Systems Filter -
The Zen Water Systems filter performed extremely well, removing 99% or better of most toxic elements.
The Zen Water System uses a 5-stage see-through filter element that also alkalizes the water by adding trace minerals after filtration.
The unit was easy to assemble and worked reliably. Two drawbacks to the unit: 1) The see-through construction allows light to provide photosynthesis energy to algae, so if water is left in the unit for a long period of time, algae may begin to grow. (It's not harmful, but might be unsightly.) 2) The unit is made primarily of resins, not stainless steel, so the long-term durability of the unit is likely not be as good as a stainless steel unit. On the positive side, however, the Zen Water Systems filter looks more visually appealing and less like a piece of survival hardware, making it a potentially better choice for offices, kitchens or healing practices.
Reduction of elements by Zen Water Systems:
ZeroWater Water Filter -
The ZeroWater water filter out-performed all other water filters tested, easily earning the top spot in terms of performance.
Astonishingly, ZeroWater removed 100% of several elements (Aluminum, Strontium and Cesium) while removing over 99% of everything else, including lead and arsenic.
This performance is virtually unheard of in water filtration technologies, regardless of the manufacturer.
The only drawback of ZeroWater filters is that they can quickly be "used up" if you try to filter high mineral content water through them such as well water. Because the ZeroWater ion exchange element binds with virtually ALL elements, its life will be reduced if you run high TDS (Total Dissolved Solids) water through it on a regular basis.
Nevertheless, because of its impressive performance, ZeroWater earns our choice as the single best countertop water filter to own for emergency use. It very effectively removes toxic heavy metals as well as elements with radioactive isotopes.
Actual results for the ZeroWater water filter:
Aluminum reduction: 100%
Copper reduction: 99.1%
Arsenic reduction: 99.3%
Strontium reduction: 100%
Cadmium reduction: 99.2%
Cesium reduction: 100%
Mercury reduction: 99.4%
Lead reduction: 99.2%
Uranium reduction: 99.1%
WaterMan Mini water filter -
Despite its small size, the WaterMan Mini water filter performed extremely well, easily out-performing nearly every other water filter tested.
The increase of strontium in the filtered water (+179%) is actually not a concern. This was a non-radioactive strontium which is typically used as an effective ion exchange medium in filtration technologies. Stronium in its stable isotope is actually a positive mineral for bone health.
Actual results for the WaterMan Mini water filter:
Aluminum reduction: 62.4%
Copper reduction: 89.2%
Arsenic reduction: 54.0%
Strontium reduction: INCREASE of 179%
Cadmium reduction: 49.1%
Cesium reduction: 25.7%
Mercury reduction: 99.7%
Lead reduction: 93.7%
Uranium reduction: 72.4%
Mavea Water Filter -
The Mavea water filter test performed relatively poorly, but unlike many other filters, it did not release additional aluminum into the water. For this reason, it's rated as superior to Pur, Brita and Culligan.
The overall ability of the Mavea water filter to removal elements was relatively poor. Based on the laboratory results, it is not recommended to buy Mavea as a water filter for the removal of heavy metals and radioactive isotopes.
Actual results for the Mavea water filter:
Aluminum reduction: 8.1%
Copper reduction: 18.8%
Arsenic reduction: 18.6%
Strontium reduction: 2.4%
Cadmium reduction: 9.2%
Cesium reduction: 15.3%
Mercury reduction: 85.0%
Lead reduction: 23.4%
Uranium reduction: 22.7%
Seychelle Water Filter -
The Seychelle water filter test performed better than most. Lead removal at 72% was respectable, and the filter removed more cesium (38.7%) than nearly all the filters tested.
Seychelle also did an outstanding job removing arsenic. For this reason, Seychelle is recommended as a reliable filter for the removal of heavy metals and radioactive isotopes.
Actual results for the Seychelle water filter:
Aluminum reduction: INCREASE of 27.9%
Copper reduction: 39.9%
Arsenic reduction: 78.4%
Strontium reduction: 30.2%
Cadmium reduction: 27.8%
Cesium reduction: 38.7%
Mercury reduction: 99.6%
Lead reduction: 72.0%
Uranium reduction: 43.2%
Culligan Water Filter -
The Culligan water filter test performed poorly, near the bottom of the performance list. (Only Brita was worse.)
Culligan only removed about 16% of arsenic, 30% of lead and 30% of cesium.
It is not recommended to use Culligan as a water filter for the removal of heavy metals and radioactive isotopes.
Actual results of the Culligan countertop water filter:
Aluminum reduction: INCREASE of 52.4%
Copper reduction: 30.8%
Arsenic reduction: 16.0%
Strontium reduction: 27.8%
Cadmium reduction: 22.6%
Cesium reduction: 30.4%
Mercury reduction: 62.4%
Lead reduction: 30.2%
Uranium reduction: 28.6%
Pur Water Filter -
The Pur water filter test performed poorly, removing relatively small amounts of most heavy metals and elements while actually increasing the concentration of aluminum in the filtered water.
Based on these results, it is not recommended that Pur water filters be used in the removal of heavy metals or radioactive isotopes.
Actual results for the Pur water filter:
Aluminum reduction: INCREASE of 46.8%
Copper reduction: 27.6%
Arsenic reduction: 19.8%
Strontium reduction: 15.4%
Cadmium reduction: 17.4%
Cesium reduction: 27.8%
Mercury reduction: 98.9%
Lead reduction: 34.9%
Uranium reduction: 31.5%
Brita Water Filter -
The Brita water filter test was the worst-performing water filter of all those tested. This was surprising, given the high popularity of the Brita water filter at retail.
Shockingly, the Brita only removed 14% of lead and about 12% of arsenic. At the same time, it actually increased the amount of aluminum in the water by almost 34%.
Based on these results, it is not recommended that Brita water filters be used in the removal of heavy metals or radioactive isotopes.
Actual results of the Brita water filter:
Aluminum reduction: INCREASE of 33.9%
Copper reduction: 8.6%
Arsenic reduction: 12.1%
Strontium reduction: 3.6%
Cadmium reduction: 6.6%
Cesium reduction: 9.5%
Mercury reduction: 74.6%
Lead reduction: 14.1%
Uranium reduction: 10.0%
Cyrstal Drop Water Filter -
The Crystal Drop water filter performed quite poorly compared to the other water filters in this testing. Its ability to remove toxic elements from water was shown to be significantly low enough that the unit should not be considered a reliable tool for the removal of toxic elements from water.
Reduction of elements by the Crystal Drop Water Filter:
Aluminum: -1165.5% (large increase in Aluminum)
ProPur Water Filter -
The ProPur Water Filter showed several problems. From the start, the assembly could not be completed because the attachment screw in the lid knob was too short to attach the knob to the lid.
The first flush of the ProPur system using the standard filters produced a heightened lead level of 5405 ppb in the flush water. This was very surprising and was not observed in any other water filter. The ProPur unit was flushed a total of five times, monitoring the lead levels in the resulting water for each flush. Lead steadily reduced to 140 ppb by the 5th flush, indicating the importance of exhaustively flushing the filters many times before using them.
The test results of the ProPur with its original filters was quite poor, indicating relatively little ability for its standard filters to remove toxic elements. In addition, the standard filters also released Aluminum into the water, nearly doubling the Aluminum concentration in the filtered water.
The ProPur unit also introduced additional lead into the water, possibly from the metal alloy used in the spigot that dispenses the water.
Reduction of elements by the ProPur Water Filter (standard filters):
Aluminum: -91.8% (meaning Aluminum was increased rather than reduced)
Lead: -26.5% (meaning Lead was increased rather than decreased)
Lead: -26.5% (meaning Lead was increased rather than decreased)
Doulton Water Filter -
The Doulton water filter performed the poorest of the filters we tested, removing surprisingly little of the toxic elements tested.
Although the unit might be perfectly capable of removing bacteria, parasites and amoeba from water, it has proven itself quite incapable of removing toxic elements and heavy metals.
Reduction of elements by the Doulton Water Filter:
Aluminum: -248.0% (increase in Aluminum)
