First, I strongly suggest that you turn your news reader to the
rec.backcountry news group and check out the "Distilled Wisdom"
panel on water purification. It has an excellent colection of
information about the risks in untreated water and the common
treatment methods. This incldues a comparison of a number of
Second, check out the conditions where you will be camping. The
risks vary considerably. In addition, water that contains quite a
bit of either silt or tannin can clog up filters pretty quickly.
Some varieties will do better in one situation or the other. Talk
with people who backpack in your area for their recommendations.
Third, what ever you get read the instructions thouroughly and
always follow them carefully. Before you go out camping, practice
using the filter and performing any field service.
Last, I would take a chemical treatment as a back up. Polar Pure
is what we use.
Now for my experience:
First Need filters are inexpensive and work fairly well, but don't
seem to last very long. We have had several of them quit near the
beginning of long trips and became heavy trash.
I use a MSR Mini-Waterworks with the ceramic filter. It is very
rugged and easy to field disassembly (which is good because it does
tend to clog on north lake country water). I like the way it screws
on to the wide mouth water bottles that many of us use.
The Pur line of filters is also widely recommended. I don't think
you could go wrong with one of these. If you are going to use the
filter for scout groups, be sure to get the larger capacity models.
