It all started HERE

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

Technology used and supported by NASA

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

Spin-offs are technology transfer products originally developed for the ISS that are adopted by companies to benefit the general public on Earth.

With more than 20 years of experience, it's interesting to compare this to other filtration technologies that are popping up everywhere these days.

Our Original Filter

Less than one millimeter thick, the filter medium activates upon contact with water and emits an electric field that surrounds the hollow volume of the pores. 

Using electroadsorption technology that employs finely pulverized carbon, the material attracts and traps negatively charged particles as well as a wide range of contaminants found in water sources around the world.

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

🔍3 Steps to Understanding Filtration🔍

Öko filter under the microscope

01

Filter Composition

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

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

1.4 micron mechanical filtration

02

Mechanical filtration

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

Submicron nanofiltration

03

Submicron filtration

When it comes into contact with water, the natural mineral fiber emits a positively charged field that surrounds the hollow interior of the pores. The water is thus stripped of submicron contaminants, which are drawn—like a magnet—to the membrane’s retention surface. This is known as electroadsorption. 

ÖKO is a revolutionary concept that combines:

  • Instant filtration technology developed by NASA;

  • A food-grade gourd body that will last for many years;

  • The FilterSure™ feature, invented by ÖKO, forces any backflow through a valve and releases air after each press so you don’t have to unscrew the bottle to continue filtering. This process not only ensures that the filter is sealed and functioning properly, but also prevents you from drinking potentially contaminated water. 

Let's take a closer look at the entire water bottle!

OKO PP5 Plastic Filter Water Bottle

This is by no means just an ordinary plastic bottle!

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

They are made from a special type of polypropylene, similar to that used in food storage containers.

An Overview of the Benefits of Polypropylene:
  • It is very flexible and compressible, which allows water to flow efficiently through the complex filtration system;
  • It is food-grade;
  • It can withstand high temperatures;
  • Itdoesn'thavea smell;
  • It is durable;
  • It is recyclable.
Our water bottle bodies have been tested by SGS, the world leader in testing, inspection, and verification.
