Silver in the Filter, Priced by Arithmetic: A Published Kill of the In-Flow Disinfection Claim, and the Narrower Claim That Survives

SIMULATED, NOT MEASURED — an arithmetic claim test. In-flow silver CT in a ceramic element is 0.52 mg.min/L fresh and 0.1 late, against a required 60-300 for 3-log kill: the disinfection claim falls short by a factor of 114 to 2857 and is killed. A narrower storage regrowth-suppression claim survives on 24 h CT of 58 mg.min/L. No device was built or tested.

Abstract

SIMULATED, NOT MEASURED — an arithmetic claim test. In-flow silver CT in a ceramic element is 0.52 mg.min/L fresh and 0.1 late, against a required 60-300 for 3-log kill: the disinfection claim falls short by a factor of 114 to 2857 and is killed. A narrower storage regrowth-suppression claim survives on 24 h CT of 58 mg.min/L. No device was built or tested.
