ÖKO H2O Filtration Water Bottle with Advanced Electro-Adsorption Filter, Portable Water Filter Bottle for Travel, Hiking & On The Go, BPA-Free Reusable Bottle, Long Lasting 100 Gallon Filter, 33.8 Oz

I've tried at least a dozen different water filter approaches, and this one is the best for the price. The bottle is well-built with a soft yet sturdy plastic. It's easy to drink out of with the usual pace of these types of filters. It packs light, though it does take up a little more space than a normal bottle for travel. I would highly recommend it for backpacking trips or international travel. Quit driving yourself crazy searching through hundreds of options. This is the one to go with.

Wonderful to use in countries where water purity is questionable. The filter is the most important thing about this water bottle. Love using it!

good but filters too weak compared to other brand

I am a long term Hydro Flask user and was having a hard time deciding on what filter to get to use with it on my travels. I gave up after reading reviews saying how hard it was to get water out using that system. I figured I'd give this bottle a go and on my last trip I put it to the test. It is pretty easy to drink from and to squeeze water out into another container when needed. How much of the yuckies does it get rid of? Well it's not a reverse osmosis system, so just enough. I wouldn't put water from a mud puddle to test it's filtration as it would clog the filter, but from the company's website I was confident enough in it to make the water better where I was going.

I just love the idea and it works, but the mouth piece you have to suck on doesn’t come out very far and it’s not as easy to get the water out.

Very good product, it is useful when you travel or hike. You will save money, earth and yourself.

I really wanted to like the ÖKO Advanced Water Bottle, but the water flow is incredibly frustrating. Even when I squeeze the bottle, barely any water comes out. It feels like I’m fighting with it just to get a sip. For something marketed as an “advanced” water bottle, this is a major design flaw. I’ve tried adjusting the cap and filter, but nothing helps. Not worth the hassle—there are better options out there.

Prompt shipping. Owed a previous version of this bottle and I was delighted to see they made some changes to improve the design to be a bit more robust.

Started leaking after few use

Es kommt kaum Wasser durch den Filter und es braucht sehr viel Kraft (mit einer Hand fast unmöglich) um Wasser aus der Flasche herauszudrücken. Sehr ärgerlich für so ein teures Produkt. Keine Hilfe durch den Kundendienst obwohl das Problem wohl bekannt ist. Hat mir auf meiner Weltreise nicht geholfen.

Bouteille d'eau pratique conserve la qualité d'eau. Sans changer le goût.

Extremely hard to drink the water from that bottle. You have to squeeze and suck in the same time and even though it's almost leaking drop by drop. Also the bottle cap is really not good designed. The filter is probably one of the best but those two points makes my drinking experience every time an inconvenient experience.

The packaging looks a bit cheap with some photoshoped picture on it but the quality of the product seem’s good
