Trying to understand so correct me if I am wrong...
So as I understand it the
#1 culprit, big nasty stuff, Giardia, Cryptosporidium, and other nasty
gastro bugs and parasites etc
2-3 microns in size.
Tablets or chlorine drops only and 4 hour wait time to kill hard shelled eggs.
A 1 micron filter will take these nasties out.
In theory an Aquamira Frontier pro (3 microns) or smaller will filter out these.
#2 culprit - Bacteria
Tablets or chlorine drops only and 30 minutes to kill Bacteria.
A Sawyer or other .1 micron filter would trap these.
#3 culprit - Viruses
None USA and mostly 3rd world countries, Central/south America, Africa, probably India etc
.005-.2 although one of the bad ones, Hepititis C is about .05 microns
Tablets or Chlorine drops and 30 minutes to kill viruses
A reverse osmosis filter will take out viruses
In theory a Sawyer .02 should take out most larger viruses like Hep C. but not
all of the smaller ones.
Steripen, Iodine, Boiling, Distilling, Reverse osmosis removes/kills all above, with the addition of distilling and reverse osmosis also removes salt.
Any comments or opinions welcome.
