Design Specifications

This filter is comprised of a large number of tiny “U” shaped hollow fiber micro-tubes with 0.02 micron absolute- size pores that trap contaminants as small as viruses, allowing the decontaminated water to pass freely. The product weights around 0,340 – 0,513 Kg and has dimensions: 149 x 184 x 184 mm. The Sawyer Point ZeroTwo Bucket Purification System kit includes: a Sawyer Point ZeroTWO™ 0.02 Micron Absolute Inline Water Purifier, a Hole cutter, Adapter, Hose, Filter Cleaner, Filter Hanger, and a Detailed instruction book. To set up the Point ZeroTwo Water Purifier, a large container to fill with water (such as a standard 5-gallon polyethylene bucket, not included) must be used. The included drill bit must be used to cut a hole 1.5 inches from the bottom of the container. The adapters must then be installed onto the bucket, and the hose connected and snapped it into the Point ZeroTwo filter. To start the flow, the filter head must be lowered below the bottom of the bucket, and raised above the bucket to stop the flow. When not in use, the filter can be hung onto the side of the bucket with the included hanger.
