Fast

SteriPEN™ water purifiers are fast. They are proven to eliminate viruses, bacteria and protozoa in 0.5 liters (16 oz) in 48 seconds. Compare this to chemicals like chlorine that take up to 4 hours to do this job or iodine, which can’t eliminate some protozoa at all! SteriPEN™’s speed means you can drink quickly.

Light

SteriPEN™ water purifiers are light. The SteriPEN™ Classic weighs less than 225 g (8 ounces) with batteries and the Adventurer/Traveler family weighs less than 110 g (4 ounces). Compare this to pump filters that weigh up to a pound or more! SteriPEN™’s light weight makes it easy to pack and carry in everything from a purse to an expedition pack.

Easy

SteriPEN™ water purifiers are easy to use. Just push the button once for a liter (or quart) or twice for half a liter (or pint) then put it in water until the indicator turns green. SteriPEN™'s integrated temperature sensor and microprocessor determine the duration of the exposure. SteriPEN™'s liquid sensors insure that the timer administers the correct duration. It’s all automatic after you push the button. Compare this to using test strips and timers with chemicals or untangling hoses and balancing bottles with pump filters. When you get water from a tap in a foreign hotel to drink or brush your teeth, the easy-to-use SteriPEN™ is just the tool for the job.
