Sawyer® PointONE™

Sawyer^® PointONE™ filtration technology uses hollow fiber membranes that exceed EPA and NSF standards. The original PointONE™ model features 0.1-micron pores that filter out 99.99999% of bacteria, while the Point ZeroTWO Purifier with 0.02-micron pores removes 99.9997% of viruses.

This system is inspired by the human kidney and the principles of dialysis. In partnership with a fiber manufacturer, Sawyer^® developed a solution with consistently accurate pore sizes and excellent flow rate.

The filters contain U-shaped microtubes with microscopic pores that trap contaminants inside while allowing clean water to flow through. Due to the high surface area of the membrane, Sawyer^® filters rank among the fastest-flowing filters available, enabling direct drinking without storing water.

All Sawyer^® filters are individually tested and certified to ensure no pore is larger than the guaranteed threshold, providing users with safe, repeatable filtration.
