We keep two Gravioxy units in our family disaster kit. No pumping or electricity required is a lifesaver. Fast flow rate and easy to pack away in minutes.

Lightweight at just 500 grams and fits easily in my pack. The 10L bag fills fast and gravity does all the hard work while we set up camp. Absolutely fantastic investment.
