Unlike a water bottle without a filter, the water flows slowly, which means you have to drink in small sips—which is great!

After testing it on a 4-day trek, the OKO water bottle proved to be very practical for long hikes. Its main advantage is clearly its built-in filtration system, which allows you to drink directly from natural sources (rivers, streams, fountains) without having to carry large quantities of water. It really saves on weight.

It’s quick and easy to use: just fill it up, screw the cap on, and drink—no fuss. The flow rate is good, which is a real plus. The filtration quality is excellent, especially on hikes where access to drinking water can be difficult.

The water bottle is durable and designed to withstand outdoor conditions. It can withstand impacts and fits easily into a side pocket. It’s easy to clean, even after several days of use.

In short, the OKO water bottle is an excellent choice for a 4-day trek: practical and well-made, it gives you more freedom while keeping your pack lighter. It’s a piece of gear I’d highly recommend to hikers and camping enthusiasts.

Very fast shipping

A water bottle I use on hikes.
Now I filter everything—water from fountains, cemeteries, streams, and the tap.
I'd have a hard time doing without it.

My Oko water bottle is always with me—at work, on hikes, at the gym, and in my car. I don’t have to worry all day about where to get water. I’m completely satisfied! I recommend it 1000%

I've been using the Oko filter bottle for two years now, and I'm here to buy one for my wife.
It even works with snow 😊

OKO's customer service was very responsive in answering our questions about compatibility before we placed our order. Shipping was fast. Installation was very easy. We're very happy with how easy it is to use, and the water no longer tastes bad. I'm thrilled to support such an ingenious idea. I highly recommend it!

While traveling in Thailand, I have absolutely no regrets about this purchase. The water here isn't safe to drink at all, and there are a lot of plastic bottles. If this helps me drink purified water and reduce my plastic consumption, I can only be happy!!

It's just AMAZING! We tested our water bottles with some friends who no longer drink the tap water at home (it tastes bad and smells like chlorine). Once filtered through the bottle's filter, the water no longer has any smell or bad taste!
Our friends are going to buy a bottle each!
My wife and I have had a bottle for several months now. We’re so happy with them that we gave them to our kids for Christmas last year. If there’s a problem, they’ll be able to filter and drink clean water, or when hiking, or abroad!

I’ve been using my öko water bottle every day for several months now (I just bought a new one because I lost the previous one). It’s become something I throw in my bag just as automatically as my phone and wallet. I wasn’t drinking enough water because I’m super sensitive to the chemical or chalky taste of most tap water, but now that’s no longer an issue—I happily drink at least a liter and a half of water every day.

A huge thank you to Oko for their incredible water bottle and top-notch customer service!
Thanks to it, we can finally go hiking with the whole family (4 people) without each of us having to carry our own water bottle. One is enough!
As soon as we come across a water source—a river, spring, or whatever—we fill it up and can continue on our way with peace of mind.
It’s so practical and reassuring when you’re out in nature.
Honestly, it’s just awesome!
Thank you, Oko, for this great innovation!

Great filter. No more chlorine taste or impurities.
I filter my water every day using the water bottle and filter.
I much prefer this filtered water to store-bought mineral or spring water.
I take it everywhere with me and know I’ll always have water that’s right for me.
No more lugging around bottles. I highly recommend it.

With this water bottle, you can refill your water anywhere, avoiding the stress of running out of water or the sometimes prohibitive costs of water abroad.

It's great—no more plastic water bottles or binchotan; I take it everywhere with me.
Super easy to assemble and the instructions are clear.
