According to the World Health Organization(WHO),

There are over 3,500 pollutants in the water of rivers, lakes, stagnant puddles and running water in most countries around the world.

These substances are the cause of many diseases, including diarrhea(TURISTA), cholera, typhoid, polio and hepatitis A and E.

Groundwater (and therefore the water in our taps) is increasingly contaminated with thousands of undesirable chemical molecules that our filtration plants are incapable of filtering out!

(pesticides, chlorine, heavy metals, drug residues, etc etc)

Using an ÖKO water filter bottle means that the water you drink is purified, healthy and safe, wherever you are.

No more plastic water bottles!

By using an ÖKO filter bottle, you regain your freedom from plastic bottles, reduce your waste, protect the planet and save over €600 a year for a couple, while avoiding the waste of 1400 plastic bottles.

Öko river water filter flask

The springs become drinkable!

The ÖKO water bottle features a patented filter developed by NASA to purify water of unwanted contaminants, tastes and odors. It can be used anywhere, and is ideal for travel, hiking, camping, sport, work and everyday use, making your bag lighter.

Öko hiking water bottle

Today, in Western Europe, pesticide residues, traces of explosives and 1,4-dioxane (a potentially carcinogenic solvent) are present in tap water in increasingly alarming doses. Not to mention heavy metals, chlorine, hormones, drugs, etc. etc.

According to the latest samples taken by ANSES at 300 sites in France(see our dedicated page)

(28 pesticides discovered in the tap water of a village in Haute-Saône).

ÖKO filtering flask

Öko bottle in brief
Filtration technology from the NASA technology transfer program

Patented nano-filtration &. 

NASA technology

This technology is called electro-adsorption. On contact with water, a positive charge field surrounds the hollow volume of the pores (through which water is forced to pass). Capable of attracting and trapping submicronic contaminants such as viruses, bacteria, micro-organisms, pesticides, heavy metals, drug residues etc. etc., it works like a magnet. It works like a magnet.

Öko high-flow water bottle

Market-leading throughput

Conventional filters use a 0.1 micron pore size, which means you have to vacuum (or use an impractical piston system) to get the right flow rate. ÖKO eliminates this problem thanks to a pore size calibrated between 1.2 and 1.4 microns. This means you can press down and get filtration as powerful as conventional filters, with a consequent flow rate!

Öko 400 liter filter

Only 1 filter to change

Every 400 L. No expiration date and no obligation to change every X months or years. As long as the 400 L is not filtered, the filter is effective!

The ÖKO Counter mobile application allows you to "count" and know how far along your filtration is so you can change at the right time!

Designed for everyday use & adventure!

Öko hiking water bottle

Eco-responsible materials

Made from recyclable & eco-responsible PP5, the soft body enables your hand to propel water through the filter! Designed and tested by SGS, it's non-polluting, BPA- and phthalate-free, and lasts 15 years!

Anti-leak system
& pipette

Peace of mind. The water bottle stopper, pipette and screw connection are leak-proof and risk-free. Your bag stays dry. The pipette guarantees impeccable hygiene.

NASA filtration technology made available to the general public (2013)

The patented filter used in the ÖKO water bottle is a product of NASA technology transfer (SPINOFF).


It works by electro-adsorption & activated carbon.

Removes submicron negative particles (and more)


Since 2013, it has been marketed in the United States, and since 2018, ÖKO EUROPE has made it available to Europeans.

Ultra-filtering system is a NASA SPINOFF

Flow rate 10 times higher &
improved filtration

Bottle filter with pressure system

Did you know that most water filter bottles on the market are impractical to use?

Here are the 2 competing systems:

By suction

Aspirating through the mouth is tiring on a daily basis. You have to suck hard to drink. For hygienic reasons, it's difficult for several people to share a gourd.

By pressure

It's the most natural thing to do, and that's what the ÖKO water bottle does. It's also practical for making tea and coffee, and filling pet bowls (dogs, cats, etc.).

  • Unfortunately, the similar filtration efficiency of all other filter bottles on the market is due to the size of their pores, generally calibrated at 0.1 microns, but impractical and unhygienic for use with low water flow rates, whether suction or pressure.

  • With pores calibrated to 1.4 microns and nano-filtration technology taking over below the micron level, this patented filter provides the solution, delivering 10 times greater water flow while maintaining powerful filtration performance! Daily use is simplified and hygiene is impeccable.

ÖKO filtration

3 steps to understanding 🔍

Öko filter under the microscope

01

Composition

The filter is composed of natural mineral fibers incorporated with activated carbon (AIO pseudoboehmite), which emits an electro-magnetic field specific to electro-adsorption.

It surrounds the pore volume, attracting submicron contaminants like a magnet.

1.4 micron mechanical filtration

02

Mechanical filtration

During this stage, all particles greater than or equal to 1.4 microns are mechanically retained.

This level of filtration, coupled with activated carbon, retains plastic micro-particles, BPA, chlorine, bromine and most limescale. It removes bad taste and odors.

Submicron nanofiltration

03

Electro-adsorption

Positively charged (attraction and retention), the fibre attracts and traps harmful agents smaller than a micron (1/1000 millimetre) such as viruses, bacteria, micro-organisms, pesticides, heavy metals, drugs, etc etc.

Contamination, disease and stomach upsets are avoided.

ÖKO filter removal capacity

Although all the tests have already been carried out, 

ÖKO EUROPE has financed its own analyses via the independent laboratory EUROFINS.


Concerning the main contaminants present in tap water (in our countries) by 2023: pesticides and metabolites, heavy metals and fluoride. 


Before and after filtration

By way of example only!

Do not reproduce (pores will clog more quickly)

(VISUAL instant filtration)

Take the ROBINET test instead!

  1. Fill the flask with tap water (filled with chlorine and other water with its own smell, taste and texture).
  2. Squeeze water into a glass, drink and taste it
  3. Open cap, drink unfiltered water directly
  4. Immediately discover the marked difference in taste between filtered water, free of all harmful substances, and unfiltered water straight from the tap.

Choosing ÖKO means choosing, without compromise, the best solution for drinking fresh filtered water anytime, anywhere, while doing good for our planet!

FAQ

How do I know when my filter is due for renewal?

Good question.
Take a look at the video of ÖKO EUROPE's mobile application: ÖKO Counter, available free of charge on Android and iPhone.

Using the app is the ideal way to avoid over-consumption of filter and to know exactly when the filter is due for renewal. The latest version of the app includes a notification system so we don't forget to increment our daily consumption.

The filter lasts 400 liters and costs €29, which represents a cost per liter for healthy water of €0.0725.

How many filters need changing?

Most gourd filters have 2 filters to change (carbon + 0.1 or 0.2 micron) which have different lifetimes (e.g. change the carbon every 100L THEN the 0.1 micron every 400L).


Not so with ÖKO EUROPE's ultra-filtering water bottles!

Only onefilter needs to be replaced every 400 liters.

Which countries are sufficiently filtered by ÖKO EUROPE?

ÖKO Europe's filtration is functional and sufficient in many countries.

You'll find the list in the detailed table here.

There are now more than 120 countries.

Is the ÖKO water bottle fragile?

The water bottle is designed to be carried in a backpack without risk. It won't puncture or leak. You can use it with peace of mind.

What diseases / particles does the ÖKO EUROPE filter protect against?

The ÖKO Europe filter bottle protects against a multitude of potential health threats.

It is designed to filter :

  • Viruses, which are micro-organisms responsible for various infectious diseases transmitted by water: norovirus, polio, hepatitis a and e,... ;
  • Bacteria such asEscherichia coli, which can cause disorders ranging from simple intestinal problems to potentially fatal kidney disease, or Salmonella typhi, which can lead to infections such as typhoid , or Vibrio cholerae bacilli, which spread cholera;
  • Parasites such as the cryptosporidium parasite, which causes symptoms similar to severe gastroenteritis and can be fatal;
  • Endotoxins that can cause severe immune reactions;
  • Chlorine, criticized for its health hazards (it is a disinfectant...) and for altering the taste of the water;
  • Lead and certain heavy metals, which in high doses can affect the brain and nervous system;
  • Herbicide and pesticide residues, which end up in large quantities in our tap water and are potentially carcinogenic;
  • Drug residues with variable effects (France is one of the world's biggest consumers of drugs);
  • Fluoride, one of the harmful effects of which, dental fluorosis, affects 2% of children in France.


Turista, also known as traveler's diarrhea, is an acute gastroenteritis resulting from an infection caused by bacteria (such as coli bacteria, campylobacter, salmonella, shigella...), parasites (such as cryptosporidium, lamblias, amoebae...) or viruses (such as rotavirus).

The ÖKO EUROPE water bottle filters out bacteria, parasites and viruses to over 99.98%. You'll also be protected against turista.

Can I drink seawater with an ÖKO EUROPE filter?

No, the dissolved salt is not filtered by the ÖKO flask. You need reverse osmosis to drink seawater.

Can I drink stagnant water with the ÖKO EUROPE filter?

Yes, you can filter and drink all fresh water, even stagnant water.

Be careful, however, as the filter will clog more quickly with muddy or extreme water.

Can I drink water from lakes, fountains, rivers or puddles with the ÖKO EUROPE filter flask?

Yes, that's what makes the ÖKO EUROPE water bottle an indispensable ally for hikers and trekkers. No need to carry liters of water for the whole family, or run the risk of running out.

Can the ÖKO EUROPE water bottle be stored in the fridge?

Yes, that's no problem at all.

Isn't tap water safe?

The use of chlorine as a disinfectant poses an initial health concern.

What's more, hardly a year goes by without an area of France, Belgium, Switzerland or Luxembourg being declared unfit for tap water consumption for a certain period. You can make up your own mind by typing the search"alerte eau robinet" for example.
You can also discover our page on contaminants present in tap water according to the latest ANSES analyses.

Excellent gourd review

I'm really happy with this water bottle. I don't even think about whether the water I drink is good or not. I take it with me everywhere, training, hiking, work...everywhere! I gave one to my girlfriend who also carries it with her all the time.
Very good product

Great!

I'm crazy about these water bottles. We have 2 of 650ml. My partner thinks they leak. Nothing to say about mine. Am I more won over by my gourd or by Jan, the boss who doesn't hesitate to answer me in person? Or to give his all to prove that the gourds are really reliable?
Thank you OKO, thank you Jan 🙏
