The SteriPen Safe Water System by Hydro-Photon is an all-in-one water treatment system that includes the SteriPEN Classic, Water Bottle Pre-Filter and a Wide-Mouth Water Bottle. This system is all that is needed for treating drinking water while camping, hiking, backpacking or traveling. The 4 micron screen Pre-Filter fits snugly on the wide-mouth water bottle, protecting the drinking threads, and allows clear water to flow into the bottle while removing particulates. See the User's Guide to see how the SteriPEN Classic mates with the Pre-Filter. Ships with neoprene case for the Classic and User's Guide.
