Designed to effectively filter tap water

Tested by COFRAC-accredited French laboratories.

The water bottle and ÖKO TAP are filtration solutions for the general public.

with direct and instantaneous flow, which allow

to drink water that is cleaner than drinking water, 

directly to any faucet.

Why filter it? 

The water is safe to drink when it leaves the plant.

But between the station and your glass, it travels through miles of pipes, both public and private, 

where deposits, taste, and visible residues form in each mixer tap.

In France, this network represents approximately 850,000 km of pipes, which is impossible to completely clean up.

A serious choice 

At ÖKO, trust does not exclude control.

We have chosen to have our filtration solutions tested and retested by COFRAC-accredited French laboratories


This is a significant, conscious, and voluntary investment.

NASA, really? 


Yes, the ÖKO filter uses technology that was originally developed in 2002 in NASA laboratories.
 And above all, in practical terms 

Spin-off technologies are neither beliefs nor slogans: 

These are technologies created for the ISS which, when they are operational and prove to be entirely satisfactory, are made available to the general public after being authorized, checked, and supervised by civil authorities. 
Otherwise, they simply could not be marketed.

Debates exist, that's normal. 
But here, one thing matters: if it is sold legally to the general public, it means it has been approved.

At ÖKO Europe, we go even further: 
Our filters have been retested by independent French laboratories accredited by COFRAC
because trust does not exclude control.

The result: reliable, transparent technology designed to work effectively on a daily basis.

Moral: there is no such thing as the perfect product. It may or may not be suitable. It may filter out certain pollutants. 
but not all of them, and certainly not 100%. 
At ÖKO EUROPE, we let you choose how YOU want to do it. 
It's a matter of respect.

When should the filter be changed?

When the taste of filtered water changes and the taste of tap water returns,
it is time to replace the filter.

It makes sense:
It's the improved taste that made you choose ÖKO in the first place.
When this signal reverses, the filter has reached the end of its capacity.

If you go a little over, nothing happens.
You simply drink tap water again, as before.

One ÖKO filter = 378 liters.
→ Approximately 1 year at a rate of 1 L per day (≈ $2.50/month)
→ Approximately 6 months at a rate of 2 L per day (≈ $5/month)

There is no mandatory monthly change.
Replacement is based on your actual consumption.

The bottle and cap, where the filter is located, are fully reusable.
It is therefore a sustainable investment (without a public offering).

In concrete terms, this saves you from spending $2.50 on a small 0.5 L bottle of water,
a situation that everyone has experienced at some point, without exception.

Feedback from our users

Not all water bottles are created equal.

The way it works is simple: fill the bottle and then squeeze it, just like you would with any sports bottle. No chemicals, no excessive pressure, no suction, and no straw. They are made from odorless materials that comply with FDA standards and are food grade. 
Our bottles and filters quickly deliver filtered water with a measurable reduction of over 200 pollutants (mostly to the limit of detection). They filter out bacteria, pathogens, protozoa, certain viruses, and a host of other contaminants from various water sources around the world.

Why compressible?

The pressure exerted with our hands provides the movement necessary to pass water through the filtration system. No electricity, assembly, preparation, or waiting required. The bottle can also be used as a shaker for electrolytes (without the filter).
