The ECLIPSE Reverse Osmosis Drinking Water System from Appleton, Wis.-based Water-Right Inc. filters water four times before it leaves the faucet. First, a sediment/carbon prefilter removes dirt, sediment and other particles that cause cloudy water. Second, a membrane separates household water at the molecular level. A high percentage of invisible contaminants are reduced, such as arsenic, lead, copper and other dissolved solids. A carbon post-filter then removes any unappetizing tastes and odors.
