ÖKO for life!!
Perfect! The delivery went very smoothly, and I highly recommend the Öko water bottle.
I never leave home without it—whether it’s for everyday use, at work, or when traveling, it’s with me wherever I go.
Thank you to the whole team

Top Filters!
Thanks to the Tap Filter, I drink my filtered tap water with confidence, and I use my water bottle for hikes. The water has a neutral taste after filtration. I keep spare filters on hand, so there are no unpleasant surprises when it’s time to change them!

Awesome
As a big hiking enthusiast, I no longer have to worry about fetching water—the only question is where I’m going to go next with my Öko.

Oko: Life Strategy
Hi, I chose the tactical water bottle because of its size. It has the same filter as the other sizes and is just as effective. I can’t wait for my next long outings—in the meantime, it’s with me every day. Happy Water Bottle Day, everyone :)

Top-Notch Water Bottle
I finally feel at ease when I drink tap water. With all the pollutants that keep being discovered, it’s scary.
I’d like to install the device designed for the faucet, but I have a handheld showerhead. Is there another system in the works that would be installed before the faucet?
Even though this system is really convenient and easy to install.
Nice green water bottle 👍
Thanks, oko

Effective in Guadeloupe
I live in Guadeloupe, where water quality and water outages affect my daily life. I purchased the 1-liter filter water bottle. I’m happy with it—it’s easy to refill and maintain. I know I can safely drink filtered water. I’m also saving money because buying bottled water in Guadeloupe is very expensive—we’re dealing with the high cost of living here. I’m very happy with my water bottle, which I use at home, at the beach, on hikes, and at work. Thank you, OKO. Sophie

This water bottle is great—especially for long hikes, and even more so when you're hiking with a dog—since it lets you have filtered (and cool) water from rivers and such... It doesn't leave any unpleasant aftertaste. I highly recommend it.

Peace of mind
First of all, congratulations on the quality and professionalism of your company. As for my 650-milliliter water bottle, I’m very satisfied with it—its size is perfect for on-the-go use because it’s so compact. The water tastes great, and knowing that I can easily refill it while out and about is a major advantage that ensures I always have clean water, especially given how important it is for my health.

Pure water
I've trusted OkO for a long time. I have several water bottles for my outings, as well as the faucet filter, which is really great. I can't drink water without the OkO filter anymore because the water is so pure—I can drink it without moderation or worry. I still love OkO and remain loyal to the brand. I'm glad I discovered OkO. Long live OkO! Plus, they're a partner of my soccer team, OM. Thanks again. Sergio

All right
I bought this after a trip abroad, and I’m satisfied—I just filled it with tap water and everything went smoothly. Great filtration, convenient, nice color, lightweight. However, there are two things that bothered me: the pipette comes off every time I use it, and I had to reattach it at the two marks as indicated!! Also, it was difficult to sip water directly from the bottle or squeeze it out every time I wanted a drink, so most of the time I ended up pouring it into a glass; otherwise, I wasn’t staying hydrated enough.

Awesome device
We contacted the company by sending a photo of our faucet because we weren't sure if it would be compatible. We received a quick and clear response. We bought it, installed it, and it's really great.
We're now going to buy a few water bottles for the family.
