The Filtered water information is based on the unit I chose for my wellness center.
The costs I've computed include the purchase of a high-grade filter, replaced annually; 2 cleaning cartridges, used annually; 5 cleaning services, once every 3 years, performed by factory technicians, and the average cost of tap water, as indicated by the U.S. EPA, at the rate of $.002 per gallon.
How We Calculated the Family of Four Consumption Figures:
Figures were calculated based on a family of four, using a recommended daily water consumption formula of one-half the body weight of each individual in ounces of water. Our hypothetical family of four includes: Father - 190 lbs, Mother - 160 lbs, 13 year old son - 100 lbs, 10 year old daughter - 75 lbs.
Weights based on National Center for Health Statistics for average weights of individuals living in the United States. This family should consume 262.5 ounces, or 2.05 gallons, of water each day. The calculations above have been figured using 2 gallons of daily consumption.
