Multiple award winner (time magazine best invention), the SteriPEN® is the only portable water purifier that uses ultraviolet (UV) light to destroy waterborne microbes. 

No tablets, no liquids, no tesing, no test strips, no aftertaste, no clogging, no replacement filters, no pumping – just hold the pen in the water and 1 litre of water is purified in 90 seconds!  By far and wide the most amazing and revolutionary water purifier we have ever tested.

Whether your source is a woodland brook or an overseas hotel tap, SteriPEN purifies clear water by destroying viruses, bacteria and protozoa?including Giardia and Cryptosporidium in seconds.

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 40×40 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.

 Water Treatment Myths Busted!

An independent scientific study* has thrown more light onto the lightweight water treatment debate. The study reveals why SteriPEN is the safest choice in the plethora of devices that travelers and wilderness enthusiasts have to choose from to render drinking water safe.

Alarmingly, the study shows that most of the chemicals and treatment devices that reportedly claim to effectively treat water infected with Cryptosporidium type organisms are not in fact effective.

All the contaminated water tested was passed through a one micron filter and then was subjected to testing using most of the commonly available treatment methods. As seen in the table below, results showed that the only effective treatments were heating or Ultraviolet light delivered by a UV Lamp.
