Aloha Monkeys, I have listed a Katadyn Expedition KFT heavy duty water filter that was purchased by me ... it was never used and carefully stored... actually purchased a few.... downsizing a bit so thought I would offer this at a great deal for the Monkeys... already sold one locally for @$1000 and this is the last one I'll offer Great for large Family, groups, camping in remote areas, expeditions or Emergencies and Hurricane, Disaster preparations.... If you do a search you'll find the great reputation that Katadyn has for water filtration as well as the detailed descriptions of this filter.... Built like a tank and last forever.... I opened the box for the first time to take the pics... These go for $1200 used from what I found... and are about best price $1400 new... Take a look at the pics... I am happy to answer any questions... $GONE shipped Priority, insured with tracking to the USA only... to some smart lucky Monkey - Filter with Cartridge factory installed plus the extra cartridge (these go for around $150...)... save yourself a bunch if you are preparing for a family or large group... or going on an expedition Thanks for taking a look... Have a great weekend! Take Care and God Bless, Bear
