SteriPEN® Safe Water System (SP-SYS) 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.
