It all started HERE

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

Technology used and supported by NASA

Technology derived from a NASA spin-off
The " " filter used in the ÖKO water bottle was created and developed by NASA in 2002 to filter wastewater on the International Space Station.

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

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

For more information, visit NASA’s official spinoffs website, where ÖKO is featured:

Our original filter

Less than a millimeter thick, the filter medium activates upon contact with water and emits an electric field that surrounds the hollow space within the pores. 

Using electro-adsorption 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 over 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 1.25 microns in size, 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 positive charge field that surrounds the hollow pore structure. The water is thus stripped of submicron contaminants, which are drawn like a magnet to the membrane’s retention surface. This is known as electro-adsorption. 

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 whole water bottle!

Washable pipette tip

Protects pipette from dust (more hygienic)

 

Retractable and washable pipette

Pull to open and press to close

 

Metal carabiner

So that you can attach your water bottle anywhere

 

Carabiner holder

 

Strap hook

(Strap not included)

 

FilterSure™ Check Valve

Filter and assembly based on NASA® technology

The fiber used has a surface area capable of neutralizing and trapping billions of pathogens!

All you have to do is change the filter—that's where the real savings come in.

 

Seal integrated into the threaded section

Prevents leaks around the threaded connection during filtration

 

Highly durable polypropylene (PP) bottle with flexible walls

Meets FDA food safety standards
Tested by SGS
Temperature-resistant to prevent mold and odors.

 

Curved bottle

For a better grip

OKO PP5 Plastic Filter Bottle

This is definitely not 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;
  • It hasno odor;
  • It is durable;
  • It is recyclable.
Our water bottle bodies have been tested by SGS, the world leader in testing, inspection, and verification.
