Katadyn Steripen Pre-Filter

When in use, pour water through the durable 40x40 micron screen filter cartridge to fill the bottle. Then you're ready to purify the water with a steripen UV water purifier. Remove the filter cartridge from the Pro-Filter, insert the filter into the center of the filter, flip the bottle, and agitate the water until the steripen indicates the treatment is complete.
