SteriPEN Water Bottle Pre-filter Water Purifier Accessory

Product Highlights

Because the penetration of Ultraviolet (UV) light can be limited by debris, it is important that water be clear prior to SteriPEN treatment. Threaded for screw-top connection to the top of your Nalgene water bottle, the SteriPEN Water Bottle Pre-filter easily and efficiently removes particulates and debris, allowing the UV light of your SteriPEN to effectively treat water.
