Hello,
I'm in the process of choosing a water filter. Basically I plan to use it like a regular counter-top filter (I currently use a Brita), but I want it to be usable in the event of a long-term emergency. My local water source would be rain, snow and a nearby creek.

A neighbor recommended an RO (reverse osmosis) system but I believe those require a pressurized system and clog rapidly in less than "clean" water.

The only one I've found that seems to fit the bill is the Berkey System. Does anyone have any experience with these? The Berkey Light seems to be the obvious choice, though the other models in stainless steal look really good.
Are the other options out there?

Thanks,
Michael
