ÖKOH2O Purification Water Bottle with Advanced Filtration, Charcoal, 33.8oz | BPA-Free Reusable Bottle, Long Lasting 100 Gallon Filter, Portable Water Filter Bottle for Travel, Hiking & On the Go

I recommend this product to anyone who’s looking for a high quality, functional bottle (basically a Brita but portable!) I’ve been struggling to find a no-frills, lightweight bottle to take around with me to the gym and on hikes. All of the big brands like Hydroflask and Stanley are way too heavy and only really offer aesthetic value, which doesn’t really fit into my everyday life. This bottle makes it super easy to carry water around and I also love the filtration feature which means I don’t have to worry about where I’m getting my water. I also haven’t experienced any leaking or loosening of the lid. I would definitely recommend this to anyone in the market for a bottle they can lug around anywhere and everywhere!

AMAZING product!! If you remotely care about your health or water quality, you should be using this product instead of a regular water bottle. This is my second bottle, and I literally take it everywhere with me. It's been especially great for airports and flights, outdoor activities like camping and hiking, but even just everyday stuff like school and workout classes. I've been paying a lot more attention to water quality and trying to avoid microplastics from bottled water, so I did a ton of research before buying. From everything I found, OKO seemed to have the best filtration system out there and filters things that a lot of other brands miss. I also love that it's BPA-free. Overall, you can tell a lot of thought went into the design. It's super simple to use, easy to clean, and durable. One thing I'd note is that you need to make sure the lid is closed tightly after filling the bottle, but as long as you do that, I had zero issues with leaking. I'm also very picky about the taste of water, and the water from this tastes significantly better than both bottled water and tap water, which is a HUGE plus for me. What I didn't expect is how much I'd end up using it at home too so now I'm excited to try their tap purifier as well. Safe to say I'm never going back to Brita!!!

Been using this bottle for a few weeks now and it’s become my daily driver! Love how you get the high quality filtration with the convenience of any normal water bottle. I’ve tried other ultra filtration water bottles before, but they either require you to pre-filter or don’t have squeeze bottle functionality, making every day use a bit annoying. Also saw some other reviews about leakage, but haven’t had any issues on my end

Unfortunately, there is a small leak on my product that appeared within one month of usage. Sometimes it leaks out of the bottle from the sides and sometimes it seem like the water goes through the filter without getting filtered which can be dangerous. The leak is not huge but it's not good to have because everytime I drink and put it down I see a few drops are getting out of the bottle and can't keep the bottle sideways due to same issue. It's a shame because I think the product itself is nice.

Follow the instructions and this is one bottle that actually works as described in doing what it says. It’s easy to maintain. I look forward to using it on my upcoming European trip to make sure that I have very clean water. Hopefully avoid any stomach problems.

They work great. Good bakery.

I'm really sensitive to the taste and smell of water (even the bottled waters you buy), and this water bottle/filter does a great job getting rid of both. I'd say it's surprisingly lightweight and easy to carry, especially considering it has a robust filter attached. It's easy to carry around, especially when I'm outdoors, and I'd recommend it for anyone traveling somewhere with questionable water quality. I saw some reviews saying it's hard to squeeze, but I actually prefer that since it doesn't pour out too easily. Really happy with it so far.

I find it very hard to squeeze the bottle to get the water out. I'm disappointed with the product.

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.

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).

Awesome
