When you go camping, staying hydrated is very important if you don’t want to suffer from dehydration. Although having access to water is important, however, water purity is equally important too.

Drinking just anything to keep your fluid level up is not enough; in worse-case scenarios, it may jeopardize your health. One popular water purifier brand is Grayl, and this manufacturer has two very good water purifier bottles; Grayl Geopress and Grayl Ultralight. In this review, we highlight the key attributes of both and leave the final decision as to which to go for.

Grayl Geopress

Grayl Geopress is the flagship model of the Grayl brand. This water bottle purifier can purify up to 5 liters per minute. If you are looking for a container that doubles as a water container and a purifier, you have that with Grayl Geopress.

It is an excellent choice for camping and hitchhiking, and its purification quality is second to none. Geopress removes different kinds of viruses, bacteria, and protozoa from water and renders it clean, safe and hygienic.

The filtration system works really well, and it has a replaceable cartridge that will last for a very long time before the need for replacement. 


  • Large size capacity
  • Efficient filtration system
  • Cartridge purifies up 250 liters before the need for a new one
  • Drink directly from the bottle


  • Quite expensive 
  • Heavy

Grayl Ultralight

The Grayl Ultralight is another model by the same manufacturer. The Ultralight is similar to the Geopress, albeit with one major difference. As the name suggests, the Ultralight is much smaller and lighter than Geopress.

More importantly, it is cheaper too. The Ultralight filters water to remove impurities and can purify up to 2 liters of water per minute.

Like the Geopress, it can eliminate viruses, Protozoa, and bacteria from water. Ultralight weighs much less than Geopress with a more flexible filtration system. However, it still works just as well as Geopress.


  • Easy to use
  • Lightweight
  • Cartridge purifies up to 150 liters of water before the need for a new one
  • Comes with a hook


  • Small capacity
  • Heavy filter


Both bottle purifiers basically offer users the same value, with one having a larger capacity than the other. So, at the end of the day, the one you buy should be a matter of choice and your budget.

The Geopress costs more but can purify more water volume, unlike Ultralight. However, Ultralight is lighter and costs less. So, if comfort is a priority and you don’t want to spend more, the Ultralight is a better option. However, if capacity ranks high in your list of priorities, the Geopress ticks all the right boxes.

Before you make a final decision on which to go for, ensure you consider all important factors so as to pick the ideal model for your next camping or hiking trip.
