GRAYL GeoPress 24 oz Water Purifier Bottle - Filter for Hiking, Camping, Survival, Travel (Bali Blue)

Well made, easy to use. We bought this for travel - not for backpacking (it is pretty heavy). We have been using it for tap water in countries where it is not safe to drink. The design makes it very easy to use and the separation between dirty water and clean water works well. The quantity of water produced is good and given it takes less than a minute it is very practical. The filter is easy to fit and remove and has lasted us so far. I can only say we have not got sick as to its effectiveness. There is some chlorine in some of tap water and this has removed the taste. It is not cheap but I think it is certainly worth the money.

So I bought this entirely for the purpose of when I’m travelling rather than going to buy water from a resort, hotel, or airport. I could just use this as a portable filter to fill up water bottles and other things by filtering faucet water.It works perfectly. I just got back from a six day trip and not once did I have to buy water. This made the faucet tap water taste nearly as good as normal bottled water. It removed the chemical taste entirely from the water and I was able to drink as much water as I wanted the entire trip rather than conserving water from purchased bottled. This model the normal GeoPress is on the larger end, I was able to fit this in the water bottle side pocket of my back pack with a little effort. It is also on the heavier end comparable to a half full 16oz plastic water bottle, and when full probably two full water bottles of weight which made me keep the bottle in the fridge rather than walking around with it on me full.I will also say to make sure you listen to the directions and follow the maximum fill line on the bottle. Due to the design of the filter if you go anywhere over the maximum fill line water will come over the sides. Also, make sure you twist the cap properly to vent the pressure built up when pressing the filter. There’s a small red and green dot to show line up with an arrow on the cap to show red when it’s closed and green when it’s twisted enough to vent.All in all incredibly happy with this purchase even at this price point, since the trip was in vegas I’ve easily recouped the cost of it in the money I saved not having to buy any water at all the entire trip. A word of warning, make sure you do the pressing filter process exactly the way it tells you to. If you’re like me and try to press it shoulder level down on a table it’s possible, but a killer arm workout and much slower than if done properly.

The media could not be loaded. I've used this in the field with good results. The water filter seems to be well built and I think will hold up well over time. The compression can be a challenge if you don't have a solid place to put the base when you are filtering water. My first experience had a learning curve. I only had soft mud along the stream bank I was kneeling over and ended up using my boot to provide counter pressure. That was a lesson learned and not a problem of the filter itself. The filtered water tasted good. Once home the cleaning was straight forward. If you read the instructions the filter components, including the element, should be disassembled and allowed to sit until dry. This may take a couple of days. Don't put it away wet if you expect it to last.

Every easy to use water filter. Air plane friendly. I love too take this bottle on trips.

The GeoPress water purifier was a total lifesaver during my trip through the jungles of the Philippines. With all the uncertain water sources, it gave me clean, safe drinking water in under a minute—no waiting, no chemicals, just press and go. I honestly believe it saved me from a major health scare; while others around me were dealing with vomiting and diarrhea, I stayed strong and hydrated thanks to this purifier. It’s rugged, easy to use, and held up through heat, humidity, and rough terrain. The built-in filter handled everything from muddy stream water to suspect tap sources. If you’re traveling anywhere remote or risky, this purifier is more than just gear—it’s survival insurance.

Pros: Very effective at purifying water - I had no issues with it while backpacking. The purified water tasted great - better than at home (but then again, I had relatively clear water to grab from). You can use drink mixes with the clean water. It seems durable and is a nice size. I did not notice any leaking at all. The color is nice, and cleaning at the end of the trip was easy.Cons: A bit expensive, but worthwhile if your water source is questionable enough to need a purifier. The press feature can be fatiguing, especially if you plan on filling your hydration system with it. I filled my 3L bladder, and after the fourth press my hand felt it. I recommend using a folded up towel or some other padding to help minimize the hand fatigue.Overall, I am happy with the product, and my 11 year old was able to use it, although pressing it became a bit difficult as our hike went on. I plan on keeping for questionable “natural” water source purification, but might explore cheaper filtration systems and use that primarily when water sources are not as questionable.

Great for camping, good price and works well! Can't even taste anything weird once you filter nasty water! Make sure to read and follow care/instructions and it will last!

Great product, I have been waiting for it to come on sale.
