This is the Katadyn Combi Plus water filter. I purchased it, but only used the necessary parts, so the main unit is unused. Two filters are included. Of the part numbers in the instruction manual, parts ①, ⑦, ⑧, and ⑨ are not included. The other parts are as shown in the photos. This is a high-performance water filter that uses a 0.2-micron ceramic filter and an activated carbon filter. It is a popular model for outdoor activities, camping, and disaster preparedness. The accessories are all that are shown in the photos. Thank you.
