CRYSTAL QUEST CQE-WC-00908 Turbo Countertop Water Cooler Systems are advanced, attractive and durable. They are the perfect way to enjoy clean, crisp, filtered water without the hassle of dealing with heavy bottles and delivery schedules. Save money, space, and time with your own bottleless water cooler system. Enjoy filtered water 24 hours a day. Installs easily. Plumbs directly to your cold water line for a continuous water supply. This system has a cord that plugs directly into a standard electrical outlet. Water travels through 5 stages of filtration: In stage 1, water flows through 1 micron filter pads (1 micron equals 1/25,000th of an inch), which removes suspended particles such as silt, sediment, cysts (Giardia, Cryptosporidium), sand, rust, dirt, and other undissolved matter. In stage 2, water passes through a granular activated carbon (GAC) cartridge. GAC is universally recognized and widely used as an effective adsorbent for a wide variety of organic contaminants such as chlorine (99.9%), chemicals linked to cancer (THMs, benzine), pesticides, herbicides, insecticides, volatile organic compounds (VOCs), PCBs, MTBEs and hundreds of other chemical contaminants that may be present in water, which cause bad tastes and odors. In stages 3 and 4, water flows through a bed of media made of a special high-purity alloy blend of two dissimilar metals--copper and zinc (ERA-6500 and ERA-9500). ERA-6500 and ERA-9500 are major advancements in water treatment technology that works on the electro-chemical and spontaneous-oxidation-reduction (Eagle Redox Alloy) principles. Chlorine is instantaneously and almost inexhaustibly oxidized. In stage 5, water flows through another 1 micron filtration pad for further reduction of undesirable particles. The end result is a great reduction or the total elimination of a wide variety of contaminants.
