Abstract

A water purification apparatus comprising at least: (a) one or more water purification components (40, 43, 44, 45, 46) and water pathways (26, 28) to provide an ultrapure purified water stream from one or more water outlets, the purified water stream preferably having a conductivity of less than lμS/cm; and (b) one or more UV LED units (30,30a) located around at least one of the water pathways, a point of dispense of one of the water outlets, or both. The relatively small size of UV LED units (30, 30a) makes it possible to use them to provide local irradiation at various locations in and around a water purification apparatus, and particularly at a point of dispense (i.e. where the purified water leaves the apparatus), to prevent/inhibit microbial contamination at the air/water interface, during dispense, more particularly during periods of non-dispense.
