Protects from global waterborne pathogens (virus, bacteria, protozoan cysts), pesticides, chemicals, heavy metals, and even microplastics



Grayl GeoPress Purifier

Unrivaled Ease, Speed & Convenience. No other purifier rivals the speed, simplicity, and effectiveness of GeoPress. In eight seconds, it makes 24 ounces (710 ml) of safe, clean drinking water anywhere on earth. Tap into the world’s water sources and safely drink from sketchy spigots, hotel sinks, murky rivers, wells or lakes.

GeoPress protects from global waterborne pathogens (virus, bacteria, protozoan cysts), pesticides, chemicals, heavy metals, and even micro-plastics. It also improves taste, smell, and clarity!

The Grayl Purifier Cartridge uses a patented G3+™ Filtration Media– three filtration technologies in one for added protection:

1) A triple-charged mesh traps disease-causing germs while allowing water to flow quickly,

2) Activated natural carbon (made from coconut shells) attracts and traps many heavy metals, industrial chemicals,

3) An integrated anti-microbial agent suppresses the growth of mold, mildew and bacteria, keeping GRAYL fresh between uses.

Add a GB2 Millbank Bag to greatly extend the life of your Grayl Geopress Purifier.

    These things are awesome and this is my second (one dedicated to my car kit or as an extra for a fellow traveler), great quality and is exactly as described. I’ve taken dirty, silty water from the ground and this flawlessly filters it into fresh, clear, tasty water. I’ve used the Sawyer Mini, Micropur tabs and just boiling in metal…this is faster, cleaner, tastes way better and easier. And the price is spot on, easy decision to make and I highly recommend.

    Excellent response and prompt shipping. Kind of weird we had to pay Massachusetts sales tax, but it was not a deal breaker. Needed two of the item, only one in stock and will be ordering the second when they arrive. I expect to be hearing that in a day or two. We will be ordering from them again and recommend the company to others.

    Price was fair and it arrived timely. I have not had the chance to use this filter so not qualified to comment on it. The replacement filter was in the box with the full product.

    quick way to get drinking water. If there is water available on your route, it saves carrying it.

  17. Noreen (verified owner)

    Was looking for a water filtration system to take out in camping or emergency situations. Love this one!

  18. John Hunter (verified owner)

  19. Geoffrey (verified owner)

    My purifier initially leaked water during the fill process. With feedback from Grayl the floating seal appears to now do its job; however, the fit remains very tight and takes much longer than 8 seconds to fill.

    This has become my go to water bottle. Not just for wilderness but even when you are out of town for an event in a hotel with the wife and you got your bug out bag and Grayl with you, and you get back from bar hoppin and the coke machine is broke, no Dasani water to drink before bed. All you got is the water from the hotel bathroom sink. Just fill the Grayl and presto, no more nasty hotel water. The filters have a 10 year shelf life, so it’s not bad for home preparedness as well.
