Everything about Gravioxy



Gravioxy was a lifesaver on our five-day Scottish Highlands trek. Filtering 10 litres of stream water effortlessly while setting up camp saved us hours of hard work.

Super compact and lightweight for my bug-out bag. The water tastes crystal clean even when drawn from murky lake water. Highly recommended for every camper.

No pumping and no batteries make this gravity filter unmatched. Filled the bag, hung it from a tree branch, and had pure drinking water for our entire group in just a few minutes.
