SteriPEN Sidewinder Water Purifier

The innovative SteriPEN Sidewinder purifies 1 liter of water in just 90 seconds without any need for batteries. An excellent choice for disaster preparedness, the Sidewinder and its long lasting UV lamp can purify up to 8,000 liters of water during their lifetime.Utilizing the same technology used to treat water in municipal treatment facilities, hospitals and water bottling plants, the Sidewinder destroys viruses, bacteria and cysts, including Giardia and Cryptosporidium by using high energy Ultraviolet UV light.To purify water, simply fill the included BPA free 1 liter water bottle, screw it into the base of the Sidewinder, turn the purifier over and engage the UV lamp by turning the integrated hand crank. No batteries are needed which makes the Sidewinder an economical choice for water treatment and, most importantly, a perfect option for emergency preparedness.NOTE: Because the penetration of UV light can be limited by discoloration, solids and debris, it is important that clear, unfrozen water be used. A Pre Filter is included to filter particulate filled water before UV treatment takes place. SIDE SYS
