Re: [at-l] Re: Cold giardia and Iodine



Your getting a bit confused. 1) Viruses don't metabolize, they
parasitize. 

2) Iodine works as a bleaching agent. It oxidizes/burns the buggers. The
problem with cold water is not the rate of metabolism, but the rate of
oxidation. It simply is slower at a colder temperature. 

3) Purifiers make very little sense in US, in any case. The idea of a
purifier is to treat warmer (usually tap) water from questionable
sources overseas. The folks who use purifiers rather than filters simply
have a belt and suspenders and duct tape mentality.
