Classic 3 Handheld Water Purifier

The full-featured SteriPEN Classic 3 is an exceptionally powerful portable water purifier that includes a patented pre-filter for extra purification. The micron screen pre-filter fits perfectly on wide-mouth 1-liter water bottles and removes particulates that can get in the way of UV light in water. Operating on four AA batteries, the Classic 3 quickly and effectively eliminates over 99.9% of bacteria, viruses, protozoa and giardia that cause water-borne illness. Like all SteriPEN models, it carries the Water Quality Association’s Gold Seal, so you can be sure it’s safe and effective.
