1). The History Of The Refrigerator Water Filters By : Ray Scardigno
The earliest recorded method of water filtration dates back to 2000 B.C. where hieroglyphics depict methods of boiling water, placing hot metal instruments in water and filtering water through charcoal and sand. These early methods are thought to have been instituted to make water taste better, thus, cleaning it. Water filtration was further developed with the advent of the microscope, which made it possible to see foreign particles and contaminants in water that would have otherwise been considered to be pure and clean.
