I'm currently looking into some different ideas for "purifying" my water. I've used for over a decade a sweetwater filter system and I need another new filter for this coming season. I've been able to find a replacement filter cartride for $30 but I'm tempted to switch things up and go lighter weight.

The sweetwater system weighs about a pound or so but has been very reliable. Any personal experiences out there along with recommendations, drawbacks, and weights of the system you use?

I would even consider prefiltering and chemicals as long as the taste of the water is not like drinking from a rinsed out DOW chemical truck.

Almost all of my backpacking is done in Colorado, Wyoming, Montana, Idaho, etc. Think high mountains in the west and possibly a little desert packing thrown in.

Thanks for the ideas,

Skippy
