It all started HERE

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

A technology used and supported by NASA

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

Spinoffs are technology transfer products designed for the ISS, which are taken over by companies to benefit the general public on Earth.

More than 20 years of hindsight is an interesting comparison with other filtration technologies that are springing up everywhere these days.

Our original filter

With a thickness of less than a millimeter, the filter media is activated on contact with water, emitting a charge field that surrounds the hollow volume of the pores.

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

A broad spectrum of PFAS, pesticides, heavy metals, bacteria, viruses, fluorides, chlorine, etc. etc. allow you to drink water that's healthier* than tap or bottled water.

*Tap water meets potability criteria, and it's because standards are regularly exceeded that it's essential to filter water these days.

🔍3 steps to understanding filtration🔍

Filter composition

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

It is 8 mm thick and has over 400 pores.

Mechanical filtration

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

Submicron filtration

On contact with water, the natural mineral fiber emits a positive charge field that surrounds the hollow volume of the pores. The water is thus freed of submicronic contaminants, attracted like a magnet to the membrane's retention surface. This is electro-adsorption.

ÖKO is a revolutionary concept combining :

Instant filtration from NASA;
A BPA-, phthalate- and microplastic-free, food-grade water bottle body for many years of use;
The FilterSure™ feature invented by ÖKO, forces any backflow through a valve and returns air after each squeeze so 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.

Not an ordinary plastic bottle!

At first glance, the bodies of ultra-filtering 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.

This is PP5(official classification).

An overview of the advantages of polypropylene:

It is highly flexible and compressible, allowing water to pass efficiently through the complex filtration system;
It is free of BPA, microplastics and phthalates;
It withstands high temperatures;
No odor;
It is durable;
It can be recycled.
