Main Materials: The GRAYL GeoPress 24 oz Water Purifier Bottle is robustly designed with a beefy polypropylene exterior shell, a thick ABS plastic inner bottle, and oversized rubber grommets – the Grayl Geopress was built to survive the apocalypse and brush off 3 meter drops onto concrete with ease. However, the Geopress’ overkill durability comes with a significant weight penalty. When empty, the bottle weighs a hefty 450 g (15.9 oz) and will weigh a bit more overtime as the filter retains water and particulates. To our surprise, the bottle’s exterior shell is actually prone to collecting scratches. While the scratches are only cosmetic in nature, don’t expect the Geopress to age with grace.
Main Feature Set
Filtration: with a simple construction that features two main parts (the exterior shell and the inner bottle), the Geopress filtration method is intuitive and similar to a French Press.
To begin filtering, you first separate the inner bottle from the exterior shell to scoop up the dirty water. You then place the exterior shell on a relatively flat surface and press the inner bottle into it with a steady downwards force. As you press, the water will slowly seep through the filter and into the inner bottle. Once fully pressed, the water is ready and safe to drink. While Grayl states that it only takes eight seconds to purify a full 24 oz of water, this claim is incredibly misleading. Eight-second presses were the exception, not the rule. After the first few filtrations, the press-time increased exponentially. Within 20 presses, the time had already increased to over 21 seconds – near Grayl’s suggested replacement time. Now after 200+ presses, that time has increased to 42 seconds for 24 oz of tap water.
Cross-Contamination: to mitigate dirty water from contaminating the bottle’s pour spout, the Grayl Geo press comes with a heavy-duty top cap that screws on tightly for a leak-free carry.
This feature is why we chose the Grayl Geo press over their Ultralight model. It makes it easier to drink from, lowers cross-contamination risk, and makes the whole system more functional as a stand-alone water bottle when traveling.
Water Quality: after drinking from the Grayl Geopress a couple of hundred times from various sources, we’ve never gotten sick.
The Grayl Geopress does what it claims to do: it purifies clear water by removing 99.9% of bacteria, protozoa, viruses, micro-plastics, and heavy metals. As a bonus, the carbon filter even removes odors and tastes from water sources. However, while the water quality is excellent, the Grayl Geopress does suffer from one major usability con.
As the filter ages, it can become incredibly difficult to push down. So much so, that May was typically unable to fully filter her water on most attempts. Depending on your size and strength, the Grayl Geo press might not be worth the hassle as the press-action filtration is prone to excessive pressure build-up that acts as a strong counterforce.
(Grayl claims the filter can last up to 350 presses, before needing to be replaced – depending on water quality)
Looks-wise, the Grayl Geopress has a rugged aesthetic that gives off an outdoorsy, “I live in the mountains,” type vibe – which we dig… to an extent.
For those wanting a more urban-friendly aesthetic, Grayl offers a blacked-out bottle. For the more adventurous souls, seven funky di- and trichromatic colorways are available.
The GRAYL GeoPress 24 oz Water Purifier Bottle is a solid option for international travelers that want a double-duty water bottle – one with a built-in water purification system. And unlike UV filters, the Geopress will remove particulates in the water – giving you the best drinking quality.
Outside of international travel, the Grayl Geopress is also the most convenient water purifier for day hikes and camping. Its easy-to-use and intuitive design allow for one of the best flow rates with a little-to-no cross-contamination risk.
As long as you’re physically able to consistently push down the filter, the GRAYL GeoPress 24 oz Water Purifier Bottle is a decent option for most recreational adventures and international travel situations.
