Care guide

While the bottle itself is dishwasher-safe (top rack only), we recommend hand washing to maximize its lifespan and protect the cap threads from potential wear.

IMPORTANT: Never put the filter in the dishwasher—it will be permanently damaged.

Hand Washing (Recommended):

Remove the cap and filter
Wash with lukewarm water and mild detergent
Rinse thoroughly
Repeat if necessary

Dishwasher Instructions:
If using a dishwasher, remove the cap and filter first, then place the bottle on the top rack only. Note that high heat settings may affect the bottle over time.

Great

We just took a trip to Cape Verde and were very glad to have our filtration bottles. That being said, there are problems with leaking water that occurred with each of the 4 bottles purchased. I have concerns that that unfiltered water gets into the glass used to collect the filtered water.

Best water bottle ever!!

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!!!

Perfect for a long trip. Taste of water was good, better than from a plastic bottle. Quick to set up for use. Bottle very durable

Awesome

Others Just Filter. ÖKO Purifies.

Most filters just block contaminants, forcing water through a dense mechanical barrier. ÖKO is different: our electro-adsorptive media attracts and retains contaminants while letting clean water flow freely through. The result is faster flow and cleaner water.

Frequently Asked
Questions

What's the benefit of a squeezable plastic bottle?

We use soft plastic because it's the only material that delivers everything outdoor enthusiasts need: ultralight weight for long-distance hiking, impact resistance for rugged adventures, and the flexibility required for our FilterSure™ technology that provides fast, natural water flow.

How often do I change my ÖKO Original filter?

The lifespan of your filter greatly depends on the quality of the water you filter through it. The more contaminated the water, the shorter the life of the filter. We suggest you change it every 50 gallons for best tasting water, but it should be fine for up to 100 gallons with most tap water. Based on 100 gallons of water, you will get:

ÖKO-750 (0.75L) Adult Bottle – 580 Refills
ÖKO- 1000 (1L) Jumbo Bottle – 375 Refills

How do I clean my ÖKO filter?

Don't! Unlike basic, simple carbon filters, the ÖKO filter media is made of a high-performance and sensitive material. Subjecting the filter to harsh detergents, soapy or hot water will not only loosen its pores and reduce its performance level but may impair its function permanently.

How do I know its time to change the filter?

As a general rule, if water does not look clear, taste clean or if the flow seems to be slower than usual, the filter should be replaced.
