GRAYL UltraPress 16.9 oz Water Purifier & Filter Bottle for Hiking, Backpacking, Survival, Travel (Desert Tan)

Not quite perfect… but close enough!
Original review: I really want to love this water bottle, but I just can’t. To be fair, my use-case is slightly different than what it’s advertised for. The tap water where I live is gross and chemically, so I only drink filtered water. I have a “zero water” filter at home that I love, but I got tired of carrying around a giant jug of water every day. Then I saw this and figured that the ability to filter water anywhere was worth the price premium.The pros: it does filter water. Pretty easily too. It doesn’t taste as good as the water from my filter at home, but it’s probably 90% as good and that’s fine with me. It’s also constructed nicely and feels solid and rugged in the hand. Swapping filters is also easy, and the one way valve that allows me to add sports drink powder without damaging the filter is a pretty smart feature.The cons: this might seem nitpicky to most, but it bothers me that the cap for the drinking spout doesn’t have anything attaching it to the lid. So if you were using this outdoors (which is the use it’s advertised for) and you accidentally drop the cap and lose it, then you completely lose the ability to seal it. You also can’t open and drink from the bottle with one hand because there’s nothing holding the cap on. This seems like such an unnecessary problem for a premium bottle like this.Also it leaks… Kinda. You HAVE to keep it right side up at all times, because if you lay it on its side then it leaks water. Which means you can’t just toss it in your bag or on the car seat without getting everything wet. Basically when you put water in the outer cup and then press the inner cup down to filter it, there’s still some water left over in the outer cup. I’m not sure if this was done intentionally so that the filter doesn’t get crushed/cracked by pushing too hard, or if it’s a limitation of the filter itself, but there’s always about 1-2 ounces of dirty water left in the outer cup. There’s a small seal around the top of the inner cup to prevent that water from seeping out when the bottle is on its side, but it’s not effective. So whenever I filter water, I then immediately remove the inner cup and dump out the excess dirty water and put the inner cup back in, which solves that problem. But I have to completely remove the drinking cap to allow the pressure to equalize, again increasing the risk of losing the cap.So overall, I’m probably still going to use this bottle all the time to have access to clean water. Because I’d rather deal with these minor inconveniences than have to carry around a large jug all the time. But if I ever lose the cap I’m going to be furious. Because having to spend another $90 on a new bottle because a $1 piece fell off is going to be a tough pill to swallow.Also it’s really tall, so I can’t put it in the cup holders in my car because then it blocks the shifter (it’s a manual transmission). I’m not dinging this product for that though because that’s a specifically “me” problem. Just something to note.Edit: my original review was after about 4-5 days of use. It’s been another week or so since then and the leaking issue has gone away. I’m not sure if it just needed to break in or if I was doing it wrong at first, but it’s all good now. I still wish that the drinking cap was attached to the bottle, but I don’t think it bothers me enough to knock off a star. Maybe it’s like a 4.5 now, but I’ll round up.Also the taste has improved over the last couple weeks, and I can now have tasty clean water everywhere!

Takes all nasty water taste away!
Worth it’s weight in gold! Whenever I travel to my brother’s house their water is so yucky, full of minerals smells and tastes like Sulphur:/ I drink so many bottles of water and the waste and the microplastic is the worst. This took out ALL the nasty flavor and smell. Im seriously impressed!

Great design. Super easy to use.
This is a great product! I used it for 10 days in Mexico. I easily filtered tap water, avoided travelers diarrhea, and didn’t have to buy & throw away a hundred plastic bottles. Other reviewers said it was hard to push down. Granted, I was not filtering swamp water, but over 10 days of use refilling water bottles for multiple people, multiple times per day, I never had any trouble pressing the water through the filter. Other reviewers also mentioned it overflowing. Yup, it will do that if you fill it above the fill line! This was a perfect size for carrying in my fanny pack. I even like the color!

Good for travel
So used this in Morocco. unfortunately, still had a little bit of an issue when I wasn’t paying attention that there was ice in a drink at a restaurant, but up until then this worked nicely so I wasn’t always having to buy water and was able to use to filtered water for brushing teeth and such. It is a bit heavy for a water bottle. I often would filter through this and then poor into another thinner lighter water bottle that held more.For those who have a hard time pressing the filter down. Tip: Keep the cap off or at least the top open. Cap off is better. When it gets hard let it sit for a few seconds so water has time to go through the filter and then press the rest of the way down before adding the cap back on.

Se purifica muy rápido sin tanto esfuerzo, me gusta que el filtro es intercambiable y la botella ligera para no sumar más peso en los viajes de larga caminata

One of the kids (23) travelled around Australia and Fiji for 3 months. She used this bottle every day, sometimes as a standard water bottle. When she lived with in a Fijian family in a village, she filled the bottle from the local rivers and streams using the bottle’s push down filter system. Katie pushed and drank. All the others in her party used trendy/fashionable pieces of kit. They had to wait for their filter systems to work. Katie was the only member of her group who avoided being ill. We can’t recommend this bottle strongly enough. Still looks like new.
