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 destroys viruses, bacteria and cysts, including Giardia and Cryptosporidium, by using high-energy Ultraviolet (UV) light. 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 fill a 16 oz. or 32 oz. glass, plastic, ceramic or metal container with clear water, push the SteriPEN Classic button once for 32 oz. or twice for 16 oz., 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 16 oz. of water in less than a minute and 32 oz. in 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. The SteriPEN Water Bottle Pre-Filter is included to filter particulate-filled water before UV treatment takes place.
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.
