Water Filtration System / 5-Stage Ion-Exchange Filter / Push Button Dispenser / Filter Change Indicator # With the ZeroWater Pitcher you can get cleaner, fresher water without tapping into your plumbing line, using bulky water coolers, and wasting your money on expensive bottled water. Thanks to an innovative five-stage filtration process, the ZeroWater Pitcher offers more complete water filtration than ordinary carbon filters. When you test a ZeroWater sample, you’ll see why it’s the best-tasting water you can drink. “000" means the detectable dissolved solids have been removed. That’s why they call it ZeroWater. Unlike conventional gravity-fed water filters, ZeroWater’s Patented 5-stage ion-exchange filter delivers the only filtered water to measure absolute 000 on the TDS meter. Compare that to the levels you’ll find in other filtered waters, most bottled waters and plain unfiltered tap water—all of which contain measurable amounts of dissolved substances. Meter readings for tap water average between 75 and 300. Conventional filtered water measures between 030-500, and bottle water between 000-350. The sleek design allows for easy Storage in your refrigerator door or other small spaces. The patent-pending pitcher is the only one on the market with a spout on the handle allowing access to water without removing the product from the refrigerator. 5-Stage filtration # Exclusive push button dispenser for in-fridge use # Contemporary design # Storage compartment for Z-Tester # Offers the ability to know exactly when to change filter cartridges
