Pure water, fast

The Kiyo water bottle purifies water in as little as 60 seconds, and neutralizes up to 99.99% of bacteria in Deep Clean.

Sustainable

One Kiyo can eliminate the need for 100 plastic bottles a year, making it good for the planet (and your wallet too). 

Travel-ready

Portable and packable, the Kiyo water bottle gives you easy access to purified water, no matter where you go.

Pure water at your fingertips

Simply fill up your Kiyo bottle with water from a potable source, screw on the cap, and press the button to activate the UVC purification technology –  once for Quick Clean and twice for Deep Clean. Within minutes, you’ll have access to clean, pure drinking water.

Behind the design

Kiyo’s soft, understated silhouette takes inspiration from handmade artisan pottery, while its gentle curves and stone-like, speckled texture recall smooth pebbles from a riverbed – their edges softened over time by the flow of rushing water.

Likewise, our days flow in continuous motion, quietly shaping our life’s journey with each passing moment. Finding beauty in life’s transient nature is called mono no aware in Japanese, and we’ve inscribed these words at the bottom of each Kiyo as a reminder – for all of us – to slow down and savour the present.

    Love this bottle!

    This is the first time I’m using a UV water-cleaning water bottle and I love it so far! I’ve been using it at home with tap water and the taste of the water is near the flavor of the Brita-filtered. I’ve been using the green button and it’s quicker than 3 minutes. I’m hoping this will help me drink more water on a day to day basis. In terms of travel, I can’t wait to try it out for when I’m on the go. It makes me happy to know I’ll be buying less plastic bottles of water with this around. Thanks, Monos!

    Love But Would Like a Straw

    It’s a great product and very sturdy. Would love even more if it had a straw to make it more convenient.

    3 kiyo bottles I bought

    I love it! for the fact that I don’t have to worry drinking water taste like chlorine. I tried filling it up water from the tap and i tap 2x for extreme cleaning. oh my gosh! It does not taste/ smell like chlorine. I have been advertising it at my work.

    Subtle beauty

    Ya, I know, it’s a ‘water bottle’. But it’s gorgeous! In the week I’ve had it, the amount of compliments and interest has been (nearly) surprising. Fill, press, shake, wait one minute and your water is ready. Love the silicone bottom. No loud clunk/bang on tables etc.. Good feel/grip in the hand. Ans the loop is super handy as well. All I could ever want in a 750ml water bottle 💛
