I’m selling my Katadyn water filter. It does need a new filter but otherwise works amazing, durable and in great condition. Katadyn Combi is an all-around filter, suitable for extremely dirty water. Great for any outdoor adventure. Description: This filter moves effortlessly from backcountry to motorhome, global travels to hikes, emergency use to temporary home use. No matter where, the replaceable activated carbon means chemical-free filtering. You also get the Faucet Kit that adapts the filter for homes, boats, or cabins. - Housing has an ergonomic grip. - Supplied adapter directs water into wide-mouth 1L bottles, or Sigg bottles, to minimize spillage and the risk of cross-contamination. - Included measuring gauge is used to check minimum diameter of the ceramic element to determine when replacement is necessary. - Flow rate is 1.2L / minute. - Effective against all protozoa, and most bacteria, including smaller ones such as campylobacter. - Silver-impregnated ceramic filter element. - Nominal life of 50,000L (actual yield depends on water quality and clarity). - Granular carbon treats up to 400L.
