Micropur Tablets vs. Filtering
I used Micropur MP1 tablets to treat water on a recent 4-day hike in the Tetons. Others in our group used a water filter. I think each method has its pros and cons, but I like the convenience of the tablets. They worked great since there is plenty of visibly clean, running water in the Tetons. We waited 30 minutes typically for treatment and had no problems at all with bacteria or viruses. The tablets do give the water a very slight change of taste, but it's quite subtle and not bothersome. We did not treat water for cooking since we boiled that. That helped to limit the number of tablets we needed to bring.
