Pedant alert: chlorine and chlorine dioxide are very different. End of pedant alert.

The four-hour hold time is for cryptosporidium, luckily uncommon in the U.S. high country. It is common in certain waters, however, and I think calls for different measures--filtering or UV.

The Hiker/Hiker Pro are good filters, dependable and pump quickly. I'd also look at UV combined with prefiltering. It gets basically everything, and is only challenged in cloudy or very cold water.

Cheers,

You don't mean using both with each water treatment do you?
Lastly:), which pump filter would you recommend? If I were to get one, I was leaning toward the Hiker Pro.
