Optimum hydration
The ÖKO water bottle filter is an innovative solution for purifying the water you drink every day. Equipped with a patented filter based on technology developed by NASA in 2002, it effectively eliminates a wide range of contaminants present in tap water or water from natural sources.
Advanced filtration technology
The heart of the ÖKO water bottle lies in its nano-charged filtercomposed of a natural mineral fiber called pseudoboehmite. This filter uses a combination of pores calibrated at 1.2 - 1.4 micron and electro-adsorption technology to attract and retain submicron particles. This approach mechanically blocks sediments and impurities while removing contaminants such as :
- Bacteria (99.9999% elimination)
- Virus (99.98% disposal)
- Parasites and cysts (99.9993% elimination)
- Heavy metals (up to 99% disposal)
- Chlorine (95% disposal)
- PFAS (eternal pollutants)
- Microplastics
- Pesticides and herbicides
These performances are confirmed by laboratory testing to stringent NSF standards. (source : okoeurope.com)


Eco-friendly materials and design
Designed to be both lightweight and durable, the ÖKO water bottle is made of food-grade polypropylene (PP5), BPA-, phthalate- and microplastic-free. This material can be used for many years, helping to reduce single-use plastic waste.
Versatile use
Whether for everyday use, travel, hiking or sporting activities, the ÖKO water bottle goes everywhere with you. It is available in different capacities (500 mL, 650 mL and 1 L) to suit your needs. Its high-performance filtration system means you can drink water with complete confidence, even from untreated sources.
Ecological and social commitment
By choosing an ÖKO water bottle, you not only contribute to your health, but also to the environment. environmental protection by reducing the use of disposable plastic bottles. ÖKO EUROPE is also a partner of Water.org, an association co-founded by Gary White and Matt Damon, which has been working for over 30 years to improve access to drinking water worldwide.


Using the ÖKO water bottle
Initial preparation Before using for the first time, unscrew the cap and remove the filter. Clean the bottle body and cap in hot, soapy water, then rinse thoroughly.
Filter installation After cleaning, screw the filter firmly onto the cap. Make sure it is securely fastened to ensure optimum filtration.
Filling Fill the flask with water from the tap or a natural source.
Filtration and consumption Screw the cap back on with the filter installed, then pull on the pipette until you see two notches, indicating that it's open. Squeeze the bottle's flexible body to allow water to pass through the filter and drink directly from the pipette.
Filter and bottle maintenance
Regular cleaning We recommend cleaning the bottle at least once a week with a mild detergent. Remove the filter before cleaning. The bottle body and cap can be washed in the dishwasher, but manual washing is preferable to avoid long-term damage.
Filter maintenance The filter does not require any special cleaning. If you have filtered water containing sediment, gently rinse the outside of the filter with clean water, without using soap or detergents, to preserve its efficiency.
Filter replacement
The service life of the ÖKO filter is estimated at around 400 liters of filtered water. However, this may vary depending on the quality of the treated water.
Signs that it's time to replace the filter :
Reduced flow If you notice that the water flows less easily under pressure, this may indicate that the filter is saturated.
Return of chlorine taste or smell If the filtered water begins to have an unusual taste or smell, this may mean that the filter has lost its effectiveness.
Filter replacement procedure :
Removing the old filter Unscrew the bottle cap, then unscrew the used filter from the cap and dispose of it in accordance with local waste management regulations.
Installing the new filter Screw the new filter firmly onto the plug. Make sure it is correctly installed to avoid any leaks or inefficiencies.
Preparing the new filter Fill the flask with water, screw on the cap with the new filter, then squeeze the water through the filter to rinse it. Repeat this operation twice before drinking the water, to remove any residual particles from the new filter.
