Filtering the Facts: Some independent reviews of Grayl Water Purifiers

Being from NZ it's easy to take water quality for granted. When I did the Old Ghost Road none of us thought twice about filling our water bottles from any running stream we came across, and none of us got sick. Unfortunately this is not always the case. In fact, even in NZ, streams and rivers can often be contaminated and undrinkable. This is even more so the case when heading overseas.

Whether exploring the vibrant streets of Mexico City, savoring the exotic flavors of Bali, or embarking on a thrilling Amazon rainforest expedition, Ensuring the water I'm drinking is virus free allows me to immerse myself in the local culture and landscapes with confidence and peace of mind.

Enter Grayl Water Purifiers, a compact and innovative solution designed to quench your thirst for adventure while keeping you hydrated with pure, refreshing water wherever you roam.


One of the biggest benefits (at least in my mind) of the Grayl Water Purifiers is their ability to filter out viruses. This is a huge win for travelers venturing to places such as Mexico, Bali, and South America. These regions, while rich in culture, natural beauty, and amazing food, can also knock you down and ruin a good few days if you drink the wrong water. And I'm not talking about drinking from a sketchy pond, even the tap water in these countries can contain waterborne viruses that can make you violently ill.

Having a Grayl Water Purifier on hand gives me the ability to filter that water into clean, virus free drinkable water. So I can do that thing I had planned tomorrow, instead of hugging a toilet bowl.

But don't just take my word for it. Here are two independent reviews examining its features, performance, and real-world usability.

In the first review Outdoor Gear Lab take the Grayl GeoPress and put it to the test with backpacking in mind. They weigh up the benefits of water quality, ease of use and durability against weight, lifespan and quantity of water that can be purified.

In the second review the guys at Too Many Adapters take the UltraPress and review it for overseas travel and hiking.

Whether you're a seasoned traveler, an outdoor enthusiast, or simply curious about what options are available to you, take a read and do your research. You may find that a Grayl is perfect for you, or you may find something that better suits how you travel.

My two cents.

  • Love that it filters out viruses on top of everything else (not all of them do, be careful).
  • I personally like that it's a water bottle and filter in one. I mostly carry my own water bottle anyway so "the extra weight" does not concern me. 
  • Being able to decanter water into friends bottles is also super handy.
  • It's simple to use and just "works" which means you actually use it. Don't have to hang it from a tree, or bend over a river and suck through a straw.
