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. Do not wash with detergents or rinse in hot water as it will damage the unit.
Keep in cool/dry place when not in use
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.

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.

Annual Savings
The average user saves hundreds of dollars a year by switching from single-use plastics to a reusable ÖKO bottle.
100
Gallons Per Filter
A single replaceable filter yields months of pristine drinking water without needing constant replacement.
Zero Waste.
Real Impact.
Every refill prevents plastic waste from entering our environment. One single ÖKO filter is the equivalent of keeping hundreds of single-use bottles out of our oceans and landfills.
Certified
Performance.
We work with independent, NSF-accredited laboratories. Every drop meets the highest official standards for safety, clarity, and quality.
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.
