Virus Protection

With general filter (0.1 micron), bacteria (E. coli etc.) can be prevented, but viruses (Norovirus etc.) are too small and pass through. Grayl’s electroadsorption filter catches them too. This is reason why called “Ultimate Water Purifier”.

2. The Long Haul: Sawyer Squeeze

Biblical item for backpackers. Very light, small, and long life.
