    • 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

    • 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

    • 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

    • Best purifier/filter bottle you can buy!
Color: Oasis Green
I scored the Grayl GeoPress on a sale, which made the purchase even that more enjoyable; however, even at full price, I've found the Grayl GeoPress to be the best purifier bottle you can buy. They work excellent, filter out all the nasties that would concern you, and the filter life is excellent if well maintained. The GeoPress is my purifier bottle go-to and a product that's never let me down. Excellent company and a product you can trust to keep you safe. ... show more

    • Used it to filter tap water in South America duing a 3-week trip. Worked great. Recommended.
Color: Peak White
It is difficult to use for the first few times, but is fairly easy to use after that. We filtered all of our drinking water during our 3-week trip to South America. We only filtered tap water. If you want safe drinking water in South America, I recommend this product. We did not filter water from streams or lakes, so I can't say how long it would last in those conditions. ... show more

    • It is a great product if you have strong muscles
Color: Peak White
I like the idea of using this purifier bottle for filtering water from tap at the hotels when we travel. That makes filtered water easily accessible anywhere we go and there is no longer a need to buy bottled water on the road. The taste of the water after the filtration tastes a little weird but it is not bad. The only two negative comments that I have are: (1) It is extremely difficult for me to remove the inner sleeve from the outer bottle. I have to hold the unit in one arm and pull/twist the inner sleeve/top handle out with the other hand, and it takes maybe 1-2 minutes for me in this battle to get the two separated, leaving me with sore hands and arms; (2) it is not easy for me to push the inner sleeve down during the water filtration process. There is so much resistance from the filter that I have to put the bottle on the floor and push the top part of the inner sleeve down with the help of my body weight. It is as if this product is designed for strong people. For an older female like me, I have a lot of difficulties using this product. Therefore I took 1 star off my rating to reflect the lack of ergonomic design. ... show more
