Ann: Surface Hygiene Study, page-48

Very true Nodferatu, copper alloys have been studied with actual results published and reviewed. Copper alloys as surfaces for many fixtures/equipment have been approved by the regulatory bodies in EU & US.
As I asked before, why does OBJ not provide any actual data/results of how "effective" this technology is? ( I am not asking to give up the actual tech behind this, but the data that is behind the statement....."resulted in superior bacteria kill to the same disinfectant agents using traditional methods".
