Iodine will not kill the spore types of protozoa like Giardia and
Cryptosporidium - BUT, your basic PUR hiker or Explorer will
filter them out.
Iodine leaves a hideous taste in the water and, in my opinion,
defeats the purpose of the filter - except for removing the
spores. Unless you're traveling in a third world country or an
Urban Survivalist, I'd opt out on the Iodine and just go with the
filter. In fact, I'd rather boil the water than treat it
chemically but that's a personal preference.
The caveat is, where I hike may be different than where you
hike. I don't believe, for instance that there has been a cholera
outbreak in Virginia in the last 50 years - but your area's
mileage may vary.
It's probably a good idea to know something about the water
conditions of the place you're going before you go there (duh).
That way you can make your own assessment of the kinds of
precautions you'll need to take. Fortunately, we the taxpayers
have funded exhaustive studies of water quality in about every
place in the country you'd care to name.
The following site is a good place to start -
Ther e also a number of sites that specifically deal with Giardi
and the like. I guess I mentioned that I worry about Giardia.

I could be wrong.
