My son recently traveled for three weeks through Indonesia. Then, I traveled across the Eastern Sierra in California. Vastly different places, but we had something in common: we both utilized the water treatment system that is the Grayl GEOPRESS Purifier.


My Grayl in the wild.

We both needed purified water during our trips; he didn’t want to rely on single-use plastic bottles, and I didn’t want to risk contaminated water in the Sierra. I’ve tried a lot of different water filter systems, from pumps to gravity-based systems to straws, and none are as easy to use as Grayl. You just scoop up water from a creek, lake, river, or faucet, then press the filter down through the water vessel like you would a French press coffee container. It takes about ten seconds and while you do need to use some force, if you have a sable surface, it’s easy.

Once you’ve filtered your water, you’re good to go. I don’t like drinking my filtered water from a straw if I can help it, so I really liked the design of the GEOPRESS, which allowed me to gulp instead of drink from a straw. With the GEOPRESS, you get 24 ounces of safe drinking water swiftly.

The water bottle is heavier and bulkier than I’d like (but they do have a slimmer, lighter version if you’re willing to reduce your ounces), but it’s worth it if you don’t have to also carry a water filter or pump with you. I love the ease of arriving at a river and just scooping up my water.

GEOPRESS protects from global waterborne pathogens (virus, bacteria, protozoan cysts), pesticides, chemicals, heavy metals, and even microplastics, so you’re getting the purist water possible. The cap has a flast-flowing drink spout that can be sealed closed, and vents air while purifying (unscrew the cap a bit when you’re filtering, or you’ll be hard-pressed (pun intended) to press down the filter).

Pick up a GEOPRESS in one of four colors for $89 (less than most filter systems) or opt for the smaller ultralight filter for $59. We found options for Grayl on Amazon as well!
