Aluminum removal 除铝
Only one filter removed 100% of all aluminum (Zero Water).
Copper removal
Copper removal ranged from a low of 8.6% to a higher of 99.1%.
The average copper removal rate was 44.8%.
Copper is associated with mental insanity if consumed in very high quantities. Many homes still contain copper pipes, causing copper contamination of tap water.
Arsenic removal
Arsenic removal ranged from 12.1% to 99.3%, with an average removal of 42.6%.
Arsenic is a cancer-causing metal that's linked to cancer and organ damage. It's a common contaminant in well water.

Cadmium removal
Cadmium is a toxic heavy metal which can cause kidney damage, heart damage and hardening of the arteries.
Cadmium removal ranged from 6.6% (Brita) to a high of 99.2% (Zero Water). The average removal was 33.1%.
Mercury removal
Mercury is an extremely toxic heavy metal that can cause brain damage, kidney damage and reproductive damage.
Because mercury is a "sticky" element, it's the easiest to remove of all. Removal rates ranged from 62.4% (Culligan) to a high of 99.7% (Waterman Mini).
Average mercury removal across all the filters was 88.5%.
Lead removal
Lead is a toxic heavy metal that causes brain damage and organ damage in the human body. Natural News has found significant quantities of lead in Organic Rice Protein superfoods imported from China.
Lead removal ranged from a low of 14.1% (Brita) to a high of 93.7% (Waterman Mini).
Average lead removal was 52.5%.
Strontium removal
In its non-radioactive form, strontium is a bone-building nutrient that's often found with calcium.
Some water filters removed almost no strontium (Brita and Mavea), while the Zero Water Filter removed 100% of strontium.
One filter, the Waterman mini,
increased strontium concentrations in the resulting water, indicating use of strontium in the filter media. This is not a bad thing. Strontium is actually a nutritive mineral, much like calcium.
Cesium removal
Cesium removal is important to consider due to the Fukushima disaster and the radioactive fallout of Cesium-137.
I am intimately familiar with cesium binding and removal technologies, as I invented the patent-pending Cesium Eliminator dietary supplement that binds with and captures radioactive isotopes of cesium.
In our testing of water filters, cesium removal varied from a low of 9.5% (Brita) to a high of 100% (Zero Water).
Average cesium removal was 35.3%.
Uranium removal
Removal of uranium is crucial for those planning on surviving a nuclear accident or nuclear war. Following nuclear events, uranium and cesium both fall out of the sky in radioactive forms, settling on bodies of water which are used for irrigation and public water supplies.
Removing radioactive uranium isotopes from drinking water is a crucial survival strategy following a nuclear incident. Only two filters we tested showed an ability to remove substantial amounts of uranium: Zero Water and the Waterman Portable Alkaline Water Purifier.

Magnesium mineralization
Two water filters we tested substantially
increased the level of magnesium in the filtered water. The highest water mineralization rate was achieved by the Waterman mini filter, which is advertised as creating "alkaline water."
The claim is true. While the magnesium concentration of the water we poured into the water filters was only 1.3 ppm, the Waterman Mini increased the magnesium concentration of the resulting water to
nearly 250 ppm.
This is a substantial increase in magnesium concentration. The Seychelle filter also increased magnesium concentrations to nearly 250 ppm, indicating it has a "mineralization" component in its filter cartridge.
真的吗?
Brita我可是用了近10年啦...
如何看出滤过的效果也差?
