Water Filters / Purifiers
Hi, can anyone help me out with advice on Water Filter and Purifier pumps. As I understand it, the difference between the two is that purifiers take out viruses but filters don't (but boiling takes out viruses anyway I believe). So which to go for, do I really need a purifier or is a filter good enough. I don't like using iodine etc except in an emergency cos its a poison and tastes horrible. I was originally tempted by the First Need which is a purifier but have read that it is not very robust and a pain in the arse to use. The Katadyn's seem to be well thought of but I'm not sure how far I need to go with this stuff.
I'm going RTW and plan to camp a lot so it needs to be small, light, good flow rate and very durable. Also it either needs to be field maintainable or have easy to get replacement cartridges (or whatever) worldwide.
Cheers Andy
