Save yourself from the illness of nasty bacteria and gut-wrenching protozoa by filtering your hiking or backpacking water with the Katadyn Combi Microfilter. Drop the pre-filter hose in the water supply, attach the Kombi to the top of your water bottle, and in about a minute of pumping you're left with clean drinking water. An internal ceramic filter pulls apart for easy cleaning on the trail, and an activated carbon cartridge keeps your water tasting fresh. Externally an impact-resistant housing protects your pump from the rigors of backpacking. Included with the Kombi are a bottle adaptor, carry bag, and cleaning kit so you've got everything you need to sip high-quality H20 no matter where you are.
