If you read the label carefully, you'll note that Aquamira is to treat bacteria and viruses. If you want to zap protozoan cysts (giardia and crypto), you need a bigger dose and longer treatment time. Read the label (EPA regulated), not the website!

BTW, you will find more on water filters in the Backcountry Gadgets and Backcountry Health and Safety sections.
