I thought I'd mention the water filter I use--it's called the
Sweetwater. It's a simple pump filter with a ceramic core, through
which suspect water is forced. The ceramic core filters out
particulate matter (sediment, algae) as well as bugs, including
giardia. The kit comes with a cleaning brush and a carrying sack, and
weighs about a pound.
The intake tube comes with a small rubber float on the end, so that
the end of the tube can be suspended in the water without touching the
bottom, thus minimizing uptake of sediment, which clogs the filter
faster and makes for more frequent cleaning. You know it needs
cleaning whenever the pumping gets more difficult. To clean, simply
unscrew the core and swab it out with the brush, rinsing it, of
course, with already-filtered water.
The core should be stored in the freezer when not in use; keeps
bacteria from breeding. Also, the company which makes the filter
recycles. When you need to replace the core (after a certain number
of gallons--I'll check how many, if anyone's interested) you can take
the core back to the store where you bought it (in my case, REI) and
they'll give you $2 off a new one.
The Sweetwater seems to work fine; we used it at Lenhok'sin last
summer with no problems. I highly recommend a filter as an essential
piece of crew equipment anytime you are in the backcountry. Of
course, you can always boil your water for a couple of minutes, but
then you have to wait for it to cool before you can drink it.
