This multi-stage (six) inline filter does a lot more than just remove arsenic from water at a rate of up to 1 gallon per minute, a rate perfect for use with water fountains, bottleless water coolers, commercial coffeemakers, and ice machines. It uses all six of its filtration layers to effectively remove a number of drinking water contaminants.
- In stages 1 and 6 water flows through pre and post one – micron filters capable of removing suspended particles such as silt, sediment, cyst (Giardia, Cryptosporidium), sand, rust, dirt, and other types of unwanted matter.
- In stage 2 water flows through a specially engineered arsenic removal/reduction media.
- In stages 3 and 4 water flows through a media bed comprised of high purity KDF-55D ®, and KDF-85D ®, which operate using electrochemical and spontaneous oxidation/reduction (REDOX) principles. The combination of these two special media completely oxidizes any chlorine in the water.
While some KDF media beds can harbor unwanted bacteria, studies have shown that this particular unit reduces the likelihood of bacteria growth by as much as 90%, thus eliminating the need for silver, an element considered by some to pose health risks.
Worried about the possible addition of copper or zinc to the water in any significant amount? On a sample of water containing 2.3 ppm chlorinated water, testing after filtration detected <0.05 mg/l copper and only 0.46 mg/l zinc. The EPA has set the aesthetic levels for copper at 1.0 mg/l and 5.0 mg/l for zinc. Additionally, the human body requires both zinc and copper for good health. The FDA recommends a daily intake of 15 mg of zinc and 2 mg of copper.
- In the fifth stage of filtration, water flows through granulated activated carbon (GAC) which adsorbs a wide variety of organic contaminants, such as any remaining chlorine (99.9%), chemicals linked to cancer such as Trihalomethanes and benzene, pesticides, herbicides, insecticides, volatile organic compounds (VOC’s), PCB’s, MTBE’s and a laundry list of other chemical contaminants that may exist in your source (i.e. tap or well) water.
What about replacement filters? Will I have difficulty finding them? Highly unlikely! The manufacturer of this inline arsenic filter, Crystal Quest has existed in one form or another in the commercial water purification industry for more than thirty years.
