We support Water.org (M. DAMON)
ÖKO EUROPE is a partner of Water.org, Gary White and Matt Damon's association which has been helping to improve access to drinking water around the world for over 30 years. When you buy an ultra-filtering water bottle, you change the life of a family at the end of the world.
For even greater savings, here are the filter packs available:
High-performance filtration directly at the tap outlet
From NASA (2002)
Identical filter to our ÖKO water bottles with integrated anti-scale.
Capable of eliminating a broad spectrum of contaminants* potentially present in tap water, such as microplastics, pesticides, PFAS, heavy metals, drug residues, fluorides, not forgetting chlorine and bromine.
Preserves minerals
Our filter allows mineral salts (trace elements) such as magnesium, potassium, sodium etc. etc. to pass through.
Scientifically, they are called dissolved salts.
High filtration capacity
Our filter ensures a filtration efficiency of 485 L or 3 to 6 months, depending on the quality of the water filtered and the frequency of use.
3 months for hard water and 6 months for soft water.
*Those tested in laboratory tests
*When present, the ÖKO filter removes: 99.98% of tested viruses , 99.9999% of tested bacteria , 99.9993% of tested cysts and parasites , 95% of chlorine, tested drug residues and certain heavy metals.
Laboratory analysis of a tap water sample confirmed that no traces of plastic, PFAS or pesticides/herbicides were visible after filtration (unlike before filtration).
Detailed test conditions and results can be found on the Lab tests page.
How hard is your tap water and what impact does this have on the life of your filter?
What is water hardness?
Water hardness, also known as hydrotimetric titre (TH), measures the concentration of calcium and magnesium salts in water. It is a natural indicator that depends on the geology of the soil in which the water has circulated.
The more calcium and magnesium a water contains, the"harder" it is. The less it contains, the"softer" it is.
How do you measure hardness?
Hardness is expressed in French degrees (°f) with 1 °f = 10 mg/L calcium carbonate (CaCO₃).
What are the day-to-day consequences?
Hard water forms limescale: white deposits visible on taps, kettles, coffee machines and so on.
This can shorten the life of appliances and increase energy consumption (scaled resistors).
Highly calcareous water can make skin dry, irritated or itchy, especially for babies and sensitive people.
It makes hair duller and rougher.

Conclusion
Classification
- 0 to 7 °f: Very soft
- 7 to 15 °f: Mild
- 15 to 30 °f: Medium hard
- 30 to 40 °f: Hard
- Over 40 °f: Very hard
Estimated filter life
The filter has a nominal capacity of 485 liters, as recommended by the manufacturer.
This capacity is adjusted according to the hardness of the water in your commune (based on the latest available sample) and the estimated average consumption for your household.
Estimated capacity as a function of water hardness is calculated using the following formula:
Adjusted capacity (in liters) = -k × D + 485
Where D represents water hardness in French degrees (°f) and k is the coefficient of impact of hardness on capacity, set at 2.5.
Very hard water can saturate the cartridge more quickly, requiring more frequent replacement.
⚠️ If the flow rate decreases or the taste of chlorine returns: Replace the filter immediately.
Installation in just a few minutes
The ÖKO TAP WATER is supplied with 7 adapters:
Faucets with oval or square pipes, or without unscrewable mixers, are not compatible with most tap-mounted systems.
All other faucets are compatible, and if it turns out that your ÖKO TAP WATER is not compatible when you install it, rest assured: we'll send you a return slip, and as soon as we receive it and check that no water has passed through the filter, we'll refund 100% of your order.
Disclaimer: to test for tightness and adaptability, please do so WITHOUT the filter inside the filter cavity!

Our opinion on the ÖKO TAP WATER filtration system
We already knew about the efficiency of the filter membrane used in our ÖKO water bottles.
What needed to be validated was the mechanical system created from A to Z in order to offer you a reliable and durable product.
After several months of testing, this is now the case.
Production has begun, and we're all looking forward to its arrival on May 1, 2025!
