OKO ÖKO - Advanced Water Bottle with Filter Derived from NASA Technology, Filtered Water Bottle for Travel, Outdoors & Home, 1 L, Moss

Great bottle for travelling as it allows you to squeeze the water through the filter - much easier than sucking a straw as in some other filter bottles. Also means you can filter into a different bottle if you want extra filtered water (perhaps a friend does not have a filter or you want to boil it).

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.

You can’t squirt the filtered water into your mouth or cup. You have to literally pull on the spout with your teeth to get water.

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.

I'm not going to be drinking out of any ponds, I just wanted a water bottle that would filter out nasty chemical tastes from city water when traveling. Pros: doesn't use a straw so you don't have to suck water out of it and you can squeeze water into the hotel coffee maker. It doesn't leak on the plane with the air pressure changes. Removes chlorine/algae smell/taste. Cons: a bit bulky yet small in volume, but I guess I don't need to lug 64oz of water on the plane and I can refill anywhere. After it's about half empty you have to turn it vertically upside down to drink out of it, but still better than sucking on a straw. Overall pleased with this product.
