As your schemes get more ambitious, your destinations further-flung, and your adventures more remote, having the essentials like clean water covered is, well, essential.

Hippo is an ultra-light, palm-sized water filtration system that can be used in-line with a hydration pack, on a 28 mm standard disposable water bottle, or direct from a fresh water source. With a swift 1 litre/minute flow rate, it’s ace for camping, trekking, bikepacking, running, adventure travel, or keeping in your pack in case of emergencies. 

Hippo uses a hollow fibre membrane to filter bacteria and protozoa out of fresh water, which means no chemicals are used. This works by drawing water into the hollow core of the tubes, leaving bacteria and protozoa trapped on the outside. This method of filtration maintains a higher flow than others and requires les cleaning, so although you can easily clean the Hippo in the field, most likely you won’t have to.  

You can easily clean the Hippo by backwashing the filter. 28 mm thread on both ends of the device make it easy to backwash with a disposable water bottle. A month indicator on one end helps you keep track of your filter’s life, and the transparent window lets you inspect the filter for yourself. 

The Hippo water filtration system includes: 

  • Hippo mini filter,  

  • a 1 litre hydration pouch,  

  • a drinking straw

Hippo Filter Kit Mini water filter

I used this filter on a recent backpacking trip. It is a superb water filter. I filtered water with ease, and the flow rate was equal to other more expensive filters that are often reviewed as the fastest filters (which I have used). My friend who was on the trip ordered one as we drove home as he was so impressed with it. Buy it with confidence.
