METHOD AND APPARATUS FOR PREVENTING MICROBIAL GROWTH IN DRINKING WATER

摘要

A drinking water filter inhibits retrograde bacteria growth at the user outlet with the combination of a non-carbonaceous submicron filter element immediately upstream of the system outlet and a copper orifice element in the outlet downstream of the filter element. The copper orifice element preferably comprises a thin copper disc having a single orifice. The submicron filter element preferably comprises a hollow fiber bundle filter element.
