The handheld Katadyn Steripen Classic 3 UV water purifier uses ultraviolet light to make your drinking water safer, wherever you are. SteriPEN's germicidal ultraviolet light destroys over 99.9% of waterborne viruses, bacteria and protozoa (giardia) in water.
Suitable for hikes, travel, or any situation when pure, drinkable water is not available, this water treatment device uses no harsh chemicals, and won't change the taste or color of the water, or add an unpleasant smell. Simply press the on button, place the lamp in your water bottle and stir. The lamp automatically shuts off when the treatment is finished.
Ensure your water is always safe for drinking!

Device activates when the lamp is placed in water, simply insert and stir until the light shuts off.
