description Sawyer Select S3 Overview

The Sawyer Select S3 is a unique purifier that uses a foam-based filter to remove viruses, bacteria, protozoa, and chemicals. It is designed for high-risk water sources and international travel. The foam filter is effective but has a limited lifespan compared to standard hollow-fiber filters. It is a specialized tool for those who need virus protection in a portable, squeeze-style format.

While it is a powerful purifier, the cost of replacement foam filters makes it less practical for everyday backpacking compared to the standard Sawyer Squeeze.
