<p>A water purification apparatus (10) for household use in treating municipally supplied water for removal of solid and chemical contaminants in which serially connected first (16), second (18) and third (20) water purification stage units are contained in a compact cabinet (12) enclosure. The first (16) and third (20) stage units function as aerating and filtering units as well as to control flow through the second stage unit (18) in which a column (72) of granular activated carbon is contained with a small percentage of silver to inhibit growth of bacteria in the granular activated carbon. Each of the first (16) and third (20) units includes an interior chamber spaced by restricted aperture plates (52, 54) and contain between 3 and 5 multifaceted silicon beads (70) which function as scrubbers to remove filtered particles from filter pad units (62, 64, 66, 68) on opposite ends of each of the first and third units.</p> |
