How to Clean a Katadyn Water Filter
The Katadyn water filter was developed for hikers and backpackers so they can have a fresh supply of water while out in the wilderness without carrying water with them. The Katadyn water filter removes up to 99.9999 percent of bacteria and up to 99.9 percent of protozoan cysts. The Katadyn water filter is also small and compact enough to carry with you as you hike. After use, some cleaning is needed to keep the filter working well.
