SteriPen "SteriPEN Bottle Pack Water Purifier"

Providing optimal filtering and purification, the SteriPEN Classic Bottle Pack includes the SteriPEN Classic water purifier, a Nalgene water bottle and a SteriPEN Water Bottle Pre-filter. Utilizing the same technology used to purify water in municipal treatment facilities, hospitals and water-bottling plants, the SteriPEN Classic is the only portable water purifier that uses high-energy Ultraviolet (UV) light to destroy viruses, bacteria and cysts, including Giardia and Cryptosporidium. The SteriPEN Classic is easy to operate and purifies water quickly and efficiently without the need for chemicals or pumping. Thanks to the SteriPEN Classic, purifying water is a cinch. Simply secure the threaded SteriPEN Water Bottle Pre-filter to the top of the 32 oz. Nalgene water bottle, fill with water, remove the pre-filter, push the SteriPEN Classic button, dip it in the container and stir slightly to agitate the water. Ultraviolet light is invisible to the human eye, but a visible blue light indicates that the SteriPEN Classic is working and shuts off as soon as a full dose has been delivered. The SteriPEN Classic purifies 32 oz. in only 90 seconds! The UV light breaks down the DNA of viruses, bacteria and cysts, rendering them harmless. Because the penetration of UV light can be limited by discoloration, solids and debris, it is important that clear, unfrozen water be used. When clear water is unobtainable, the SteriPEN Water Bottle Pre-filter easily and efficiently removes particulates and debris prior to the UV water treatment. The SteriPEN Classic requires 4 AA batteries, sold separately. Alkaline or lithium batteries will work in the SteriPEN Classic, but rechargeable Nickel Metal Hydride batteries are your best option, as they last far longer and outperform other batteries in cold temperatures. The SteriPEN Classic's electronics are designed to activate only as long as there is enough battery power available to produce the required UV dosage, so there is no risk of an inadequate dose as batteries run low. The Ultraviolet lamp used by the SteriPEN Classic is very durable, providing up to 5,000 doses. To ensure that the SteriPEN Classic provides optimal effectiveness, the lamp is automatically disabled after 5,000 doses and a red LED light alerts you that a new lamp is required.  more
