This is the countertop water purification system that uses ultraviolet light to destroy 99.9999% of germs and bacteria. Its thorough two-step process first passes tapwater through a 1-micron carbon filter which removes impurities that can produce foul tastes and odors. Then the water is treated with the same UV technology used by hospitals to destroy dangerous germs including E. coli and salmonella. A superior, simpler alternative to bottled water and installed filtration systems, the countertop unit purifies water as it is dispensed, and all plastic components are BPA-free and coated to resist mold and bacteria. The 1 1/2-liter reservoir can be detached and stored in the door of a refrigerator, and the carbon filter and UV bulb last about one year. Plugs into AC. 12" H x 5 1/2" W x 12 1/2" D. (8 lbs.)
