I will be traveling to Africa to climb Mt. Kilimanjaro in December, and I m looking for the best purifier around. The tour company said that Water Tech or First Need is good, but you seem to like the PUR Explorer.
Filters are fine for giardia and creepy-crawlies of that sort, but won t kill viruses.
That s what a purifier can do. I m not familiar with the Water Tech purifier you mention. It s an effective filter, but there have been some complaints that it clogs fairly easily.
