The HydroPress Gravity Filter is SummitBase's hands-free water treatment system — fill the dirty-water reservoir, hang it from a branch or trekking pole, and go set up camp while 2 or 4 liters filter themselves. No pumping, no squeezing, no attention required. The 0.1-micron hollow fiber filter removes 99.9999% of bacteria and 99.9% of protozoa at about 1 liter every 3 minutes.
An ideal group and base camp solution: the 4L version can filter enough water for dinner, morning coffee, and breakfast while your group does camp chores. Backflushes easily in the field to restore flow rate. The dirty-bag and clean-bag system keeps water sources clearly separated.
