SteriPEN Discontinued The Journey LCD in Fall 2014
The SteriPEN Journey LCD is a light, fast, and high tech system for purifying water, using UV light technology. Though the SteriPEN does not filter out particulate unless you purchase a separate pre-filter, it does treat viruses, which is more than most pump filters, and it does so without adding chemicals to your water like the Katadyn Micropur Purification. At 7.82 oz. for the device, batteries, pre-filter, and case, it is far lighter than most other filters, which average around 11 to 13 ounces. The SteriPEN is also one of the fastest treatment systems for a single liter of water, taking only 90 seconds, with the Platypus GravityWorks working slightly faster. Unfortunately, the SteriPEN has a list of limitations. The batteries require frequent replacement, the water on the threads of your bottle are not treated, it only works in certain sized bottle openings, and multiple backcountry users have reported device malfunction with this model. It seems that SteriPEN has resolved some of these issues in some of their other models, such as the SteriPEN Adventurer Opti and the SteriPEN Freedom. If you prefer something that does not require charging or changing batteries but that also treats for viruses, check out the First Need XL pump filter.
