Spending lots of time outdoor? The outdoor line keeps you hydrated when on the go. Outdoor SteriPENs treat up to one liter of water, last for 8,000 treatments, and are powered by internal rechargeable, CR123 batteries, or AA batteries.
When camping or hiking, it's convenient to draw water from fresh water sources rather than carry a supply. To be safe for drinking, water should be filtered or purified.
Water filters can be difficult to use and inconvenient. Iodine or other additives affect the taste and are time consuming. Ultraviolet light is the preferred method for outdoor adventures because it purifies water quickly and conveniently without affecting taste.
Even a stream that looks clean may not be. Microorganisms from animal and human waste and are spread by water run-off. Since we can’t visually detect contaminated water, it’s best to protect yourself with a water purifier.
