Re: water filters

From the multi-pure website it says that it can get rid of down to 0.5 microns, (is it written somewhere else about the system, I just found it in faqs), which means it still wouldn't get rid of
Bacteria: Cholera, E. coli, Salmonella: 0.2–0.5 microns and
Viruses: Hepatitis A, rotavirus, Norwalk virus: 0.004 microns

Which look like they need a microfilter or water purifier (not filter) for those sizes respectively.

From a backpackers field manual website:
There is a difference between a water filter and a water purifier. Filters do not filter out viruses, but there are water purifiers, like the PUR Scout, that pass the water through both a filter and an iodine compound that kills any smaller organisms that have passed through the filter. These purifiers kill all microorganisms down to 0.004 microns; however, the filter should not be used by people who are allergic to iodine.

I have a super sensitive stomach so I have tried to do lots of research but there is so much out there, that I really don't know, hoping my stomach will just get used to it, at least a little bit!

Looks like this is a common topic, looks like from Jan! I must have missed it
