Multiple award winner (time magazine best invention), the SteriPEN® is the only portable water purifier that uses ultraviolet (UV) light to destroy waterborne microbes.
For those who already own a wide-mouth water bottle, SteriPEN offers the Classic with Pre-Filter Pack. The Classic with Pre-Filter pack is all that is needed when camping, hiking, backpacking or traveling. Use the 40x40 micron screen Pre-Filter to remove particulates from the water. The Pre-Filter is designed to be stored directly on the wide mouth bottle. Comes with neoprene carry case and User Guide.
Like all SteriPENs, the Classic is Fast (48 seconds for 0.5 L (16 oz.)), Light (128g /4.5 oz.), Effective, and even easier with its LED light indicator which tells you when cycle is finished.
Uses 4 x AA batteries (not included) which is great for travel because AA batteries are available worldwide unlike other models with small c-type batteries.
