    • My thought about the Grayl Purifier Bottle filter system
Color: Bali Blue
I have always used a Sawyer purifier and it is easy and light to use. The Grayl as a storage unit is heavy. But for me it gives me peace of mind. It cleans the water so well, it gives me confidence. I do not want to get sick. I think best for Car and motorcycle or even bicycle camping, and all my kayak trips I have it with me. Not so much for section hiking. Too heavy. But I'm happy with my purchase and hope to get much use out of it. Very easy to use and easy to clean. ... show more
Reviewed in the United States on July 7, 2026 by I bought this headlight and it had bad circuit because it would operate and if you moved your position it would shut off. Move it around and it would come back on. Could not send it back because of time limit on return. So I bought another one and it does the same thing. Beware.
    • Amazing filter...mind the quirks and you'll be a happy camper
I'm a practical person and decided this was the best filter to get since it does so much more than others. It: -Removes bacteria & viruses PLUS chemicals and microplastics. This is good for survival situations as well as camping. And with so much plastic in the environment, it's possible that even wilderness water sources have some degree of plastic and chemical contamination. This is really an "overall" solution for today's water issues--everything but desalination. -Improves taste & odor -Takes less time and grunt work than other systems -Has a super simple design and no small delicate plastic parts that could break easily on trail We took it on a backpacking trip recently that had only lake water (no springs) and on a car camping trip with river water. It absolutely makes water taste great and no one got sick. Overall it's wonderful, but it takes a bit of getting used to. Here are the quirks we discovered: 1. For people just buying it, please note that you have to unscrew the cap to press the thing down, or water will spill up and out the sides. I never read the instructions but figured that part out by trial and error. Unscrewing the cap gives a way for air to get out so you don't end up wasting water by having it come up and out the sides. It's also VERY hard to press down when the cap is screwed on. 2. It's a bit hard to press down, even with the cap unscrewed. My husband did most of it for both of us. For me to do it myself, I find it easier to set it on the ground or something pretty low and lean over it, using my body weight to press. Press slowly--if I counted to ten it was easier than if I tried to force it down. 3. It's easy to think you're done pressing, then find out you missed a bit because water leaks out the sides. Once you're done pressing, press again 2-3 times to make sure the lip of the press part is totally flush with the top of the bottle. You can test it by tilting the bottle and seeing if it drips, or looking closely. It would be easy to think the bottle was defective if it leaked and you didn't realize you hadn't pressed it all the way down. 4. Sometimes while pressing, water would spill out the sides even with the cap unscrewed. If you look closely, there's a faint fill line on the back side of the bottle, about 4/5 of the way up. If you fill exactly to this line and not above, you won't have water spilling out the sides. It took me a few tries to figure this out. I thought you had to guess how high to fill it and was carrying wasted air space in the bottle before my son noticed and pointed out the handy line. 5. As a side note, at one campground we had amazing spring water piped into the campsite. I filled the Grayl from the top (no filtering) with this awesome water to bring home. Several weeks later it still tastes fresh and sweet. The same water "soured" a bit in other containers after sitting a while. Not sure why the Grayl performed better as a storage bottle, but it did. The system is a bit heavy, but it doubles as a water bottle so it's not wasted space. And it's the only one that does everything in one. If you're on the fence, just buy this one. Once you get used to its quirks, it's unparalleled. ... show more

    • Ideal if you have young kids
If you have young kids, this is your answer. I needed an easy purification system to use while hiking with my kids, and I needed something that would produce water "normal" enough for a young kid to drink abundantly. The Grayl was a home run. This filter works great, but it is especially perfect if you are traveling with kids. I took one of my kids (8 yrs old) on a short backpacking trip this summer and this was the ideal filter. She can't really work the slowish straw-type or pump-type filters; adding the purifying drops makes the water taste like medicine and sometimes you have to wait awhile; and the UV-light systems might kill the bugs but the water remains silty or murky. The Grayl solves all of those problems. My kid isn't a wimp; she would have reluctantly drunk murky or bad-tasting water, but she drank a lot more water (esp. important in July) since I could refill her water bottle with clear, great-tasting water as quickly and as often as she wanted. The second time I used the Grayl (long day-hike), I was able to continuously refill the water bottles for the entire family. Again, it was super convenient and not difficult to convince the younger kids to drink the clear and clean water that came out. Maybe it's not 100% perfect: it's a little hard to push the inner bottle down (but not that hard). I squirt myself in the face sometimes as excess water comes out the sides as I push down, but with young kids this thing was absolutely worth its weight in gold. The water looks and tastes like fresh clear tap water, and you can refill others' water bottles as much and as quickly as you want. Like I said (wrote) above: Home Run. ... show more

    • Excellent for travel.
Color: 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. ... show more

    • Effective at purifying, great tasting water, maybe excessive for most hiking adventures.
Color: Coyote Brown
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. ... show more

    • Fantastic device, works amazingly well- but requires strength to use
Color: Peak White
This is a fantastic product, but read my one concern. I took it on a canoe/camping trip and used it constantly. So much better than boiling water and drinking warm water. Now you really can drink directly from the lake or river. Turned water with sediment swirling into crystal clear, cold water. However... it takes a lot of strength to use. The best method was to put it on the ground and use your body weight to slowly press down on the water. Using my full body weight made it simpler. I also did it in the canoe, where I was only able to use my arms, and that was doable, but more difficult and took longer. I wondered if my wife would have been able to operate this. Make sure to read directions well before tossing them. ... show more

    • Hotel travel lifesaver
Color: Oasis Green
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. ... show more
