Best Chromium Water Filter Systems for Hexavalent Chromium 6
Chromium 6 (Hexavalent) is a dangerous carcinogen linked to stomach and other gastrointestinal tumors. The atomic diameter of chromium is .000256 microns. The Chromium water filters that we recommend below all filter out particles down to .0001 microns. This means that any of these water filter systems will effectively filter out chromium 6 from your drinking water. Not all reverse osmosis water filter systems remove Chromium 6 (Hexavalent) as effectively as others. We have done exhaustive research of many, many Chromium water filter systems. We have looked at virtually all brands available today. We did not limit ourselves to just products we carried, but sought the widest cross-section of Chromium water filter systems available because we understand how important it is to you to remove the maximum Chromium from your water. Below are the most effective Chromium water filter systems we found from all the Chromium water filter systems we looked compared.

Operating Pressure RangeOperating pressure range is the min and max range of water pressure that the system will operate under for optimal production/performance. Most homes on city water average between 55 psi - 65 psi of static water pressure. More water pressure is not necessarily a good thing for some systems.

In 2009, California officials proposed setting a "public health goal" for hexavalent chromium in drinking water of 0.06 parts per billion (ppb) to reduce cancer risk. Hexavalent chromium (or chromium-6) gets into water supplies after being discharged from steel and pulp mills as well as metal-plating and leather-tanning facilities.
Chromium has several different forms. Trivalent chromium (chromium-3) is a nutrient essential to sugar and lipid metabolism, but hexavalent chromium (chromium-6) is a dangerous toxin.
People with less acidic stomachs appear to have limited ability to convert hexavalent chromium to trivalent chromium, exposing them to higher levels of the toxic form and putting them at greater risk. Children and infants also are more vulnerable to chromium 6 and its effects because their bodies are less able get rid of this harmful chemical.
Chromium 6, hexavalent chromium, chromium in drinking water is likely to raise everyone’s risk of cancer but it can be significantly reduced by using a chromium water filter system.
