Howdy all.

Wife and I are looking for some good water purification systems that would be a good fit backpacking with less than trust-able water near by. Might be taking a trip to Peru next year and backpacking the Andes mountains including Machu Picchu. Can't trust the water in the faucet, or in the streams, so need good filtration, long life, and compact size. Price is the least important factor.

I've got a big pump driven system for here at the house, but these will also serve as a good backup for BoB when not used backpacking.

So what works well, and what do you recommend?

Thanks,
