User Review: Katadyn Pocket
Price Paid: $305 CND
Terrific filter, worth every penny and more. Used on a week-long canoe trip as the only filter for 8 campers. Pumping became a bit harder (and stayed that way even after cleaning) towards the end of the trip but was still pretty easy to use. Filtering a 1L bottle takes 2-3 un-flustered minutes though if pumping hard, you can do it in a minute flat.
Easy to clean and maintain. A bit heavy but will take a lot of abuse (just don't drop it in a lake!). At 13000 gallons per filter cartridge it's at least $1,500 cheaper per gallon than any other filter.
