Every time you turn on a drinking faucet, source water passes through a 5-micron sediment filter that traps particulate matter — such as dirt, rust, and silt — that can affect the taste and appearance of your water, and potentially clog the system. A 5-micron GAC filter reduces chlorine taste and odor, as well as mineral oil, BTEX, Poly aromatic hydrocarbons (PACs), phenol, and halogenated substance. At the third stage, a denser carbon block filter removes any residual color, taste and odds (CTO), as well as difficult-to-remove chemicals such as chloramines. The system's fourth stage of filtration is especially important, as it involves the pressing of water through the NSF certified reverse osmosis (RO) membrane, the same technology used to produce bottled water. This semi-permeable membrane features tiny holes at a size of 0.0001 micron (µm) effectively removes arsenic, lead, perchlorate, chromium, copper, TDS (total dissolved solids), sodium, and a long list of other water contaminants. It also removes parasitic cysts, such as giardia and cryptosporidia. The 5th stage of filtration utilizes a finer GAC filter, which works as a final polishing filter when the water leaves the storage tank. The 6th stage features alkaline and mineral filter that adds a small amount of calcium and magnesium minerals (30-60 mg/l), just enough to make the water slightly alkaline and improves the taste. The end result is consistently great-tasting water at merely one cent per bottle. Besides helping your family, with any type of iSpring water-filtration product you use you may also prevent up to 16,000 plastic bottles from polluting the environment — all in the time it takes to use and replace a single filter.
