It all started HERE

Miles above the earth, the International Space Station (ISS) is where our technology was originally used.

A technology used and supported by NASA

The filter used by the ÖKO water bottle was created and developed by NASA in 2002 to filter wastewater from the ISS.

Spin-offs are technology transfer products designed for the ISS that are taken up by companies to benefit the general public on Earth.

More than 20 years of hindsight is interesting when compared to other filtration technologies that are popping up everywhere these days.

For more information, visit NASA's official spinoff website, where ÖKO is featured:

Our original filter

Less than a millimeter thick, the filter media activates upon contact with water and emits a charge field that surrounds the hollow volume of the pores.

Thanks to electro-adsorption technology using finely pulverized carbon, the material attracts and retains negatively charged particles as well as a multitude of contaminants present in water around the world.

ÖKO filtration technology is designed to reduce the presence of more than 200 undesirable pollutants (if present) such as PFAS, pesticides, heavy metals, chlorine, fluorides, as well as certain viruses, bacteria, and particles (see the analyses carried out by COFRAC ISO/IEC 17025 accredited laboratories on our dedicated page).

🔍3 steps to understanding filtration🔍

Filter composition

The filter membrane is composed of a natural mineral fiber (pseudoboehmite AIOHH), antibacterial ions, and a microscopic sprinkling of activated carbon.

It is 8 mm thick and has more than 400 pores.

Mechanical filtration

Its pores are calibrated to 1.25 microns, mechanically blocking all particles larger than or equal to this size, such as sediments and impurities.

Submicron filtration

When it comes into contact with water, the natural mineral fiber emits a positive charge field that surrounds the hollow volume of the pores. The water is thus stripped of submicron contaminants, which are attracted like a magnet to the membrane's retention surface. This is electro-adsorption.

ÖKO is a revolutionary concept combining:

Instant filtration developed by NASA;
A food-grade bottle body that can be used for many years;
The FilterSure™ feature invented by ÖKO forces all backflow through a valve and returns air after each press so that you don't have to unscrew the bottle to continue filtering. This process not only ensures that the filter is sealed and working properly, but also prevents you from drinking potentially contaminated water.

Let's discover the whole bottle!

The complete ÖKO EUROPE water bottle filter

Washable pipette protector

Protects pipette from dust (more hygienic)

Retractable and washable pipette

Pull to open and push to close

Metal carabiner

So that you can attach your water bottle anywhere

Carabiner holder

Strap hook

(Strap not included)

FilterSure™ check valve

Allows comfortable air return with each press.

Ease of use on a daily basis.

Filter and assembly based on NASA® technology

The fiber used has a retention surface that can neutralize and retain billions of pathogens!

Only the filter needs to be replaced, that's where the real savings are.

Integrated thread seal

Prevents leaks through the screw thread during filtration

Ultra-resistant polypropylene (PP) bottle with flexible walls

FDA food safety compliant
Tested by SGS
Temperature resistant to prevent mold and odors.

Curved bottle

For a better grip

Not just any ordinary plastic bottle!

At first glance, the bodies of ultra-filter water bottles look like other plastic bottles, but let's take a closer look:

They are made from a special polypropylene, similar to food storage containers.

It is PP5 (official classification).

Overview of the advantages of polypropylene:

It is very flexible and compressible, allowing water to pass efficiently through the complex filtration system;
It is food grade ;
It withstands high temperatures;
Itdoes notemitany odor;
It is durable;
It is recyclable.
