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).

Utiliser une gourde filtrante ÖKO permet d'améliorer l'eau que vous buvez.

Où que vous soyez.

Children's picture with ÖKO water bottle

Goodbye PET water bottles, long live tap water!

Vous pouvez (re)boire l'eau du robinet qui reste très peu chère (5 € le mètre cube soit 0.005 € / L). Celle-ci redevient meilleure, ôtée de beaucoup de ses contaminants et microplastiques !

And no more polluting plastics in our rivers and oceans!

Öko river water filter bottle

Non-drinkable springs become drinkable!

The ÖKO water bottle is equipped with a patented filter originally developed by NASA to convert undrinkable water into perfectly drinkable water. 

It can be used anywhere, and is ideal for all your travels (sport, travel, hiking, work, etc.), as well as at home, on tap!

With ÖKO, plastic becomes a huge advantage!

For you and our planet!


Indeed, to be able to PRESS & FILTER everywhere with your hands, you need a soft material!
That's a huge advantage for you, in fact!

Le plastique ÖKO (PP5) est alimentaire, sans BPA, sans microplastiques et sans phtalates !

It has a lifespan of at least 10 years!

This is the real saving and ecology compared to PET plastic bottles.
(ours is entirely recyclable)!

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)

ÖKO filtering bottle

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

 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!

Anti-leak system
& Retractable Soft-Bite Mouthpiece

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 filter used in the ÖKO flask is a NASA technology transfer product (SPINOFF).


It works by electro-aDsorption & activated carbon.

Removes submicron negative particles 

(and much 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

Instant filtration & flow 10 times thanks to pressure 

(no need to vacuum)

Bottle filter with pressure system

Did you know that most water filter bottles on the market work by suction?

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. Convenient for sharing and for doing it absolutely anywhere.

  • 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 1.2 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 understand 🔍

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 hollow volume of pores calibrated at 1.2 microns, so that it can attract, like a magnet, submicronic contaminants smaller than the size of its pores.

1.4 micron mechanical filtration

02

Mechanical filtration

During this stage, all particles greater than or equal to 1.2 microns are mechanically retained.

This level of filtration, coupled with activated carbon, retains plastic micro-particles, BPA, chlorine, bromine etc. etc., among other things. 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.

FAQ

Why does ÖKO use PLASTIC? I don't like it at first sight!

Pour VOTRE plus grand bien


=> It has a lifespan of MINIMUM 10 years


=> Le plastique utilisé par ÖKO est de qualité alimentaire (PP5 pour le terme officiel scientifique)

Il ne contient pas de microplastiques, pas de BPA, pas de phtalates ni d'autres substances néfastes, contrairement aux bouteilles d'eau en plastiques PP1 (PET). Il est entièrement recyclable. 


Thanks to this soft, lightweight material, your hands (or those of your children) can PRESS and PROPUTE the water through the filter.

=> For instantly healthy, purified water. Absolutely EVERYWHERE.


Unfortunately, soft glass and soft stainless steel do not yet exist. 

Glass can break and stainless steel is much heavier.


That's where the real economy lies, because all you have to change is the filter! WITHOUT POLLUTING!

What contaminants are filtered by ÖKO's L2 filter (housed in our water bottles)?

It filters efficiently :

All lab tests can be found on our website in the submenu Laboratory & Field Tests Why choose ÖKO?:

  • Viruses, which are micro-organisms responsible for various infectious diseases transmitted by water: norovirus, polio, hepatitis a and e, ... ;
  • Bacteria such asEscherichia coli (E.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;
  • Microplastics, which are present in tap and bottled water (they measure between 2 and 10 microns and are invisible to the naked eye).
  • PFASs, known as eternal pollutants (perfluorinated) because they remain in our bodies. The media covered them extensively in 2024.
  • Endotoxins that can cause severe immune reactions;
  • Chlorine, criticized for its health hazards (it's a bacteria killer, but our microbiota is made up largely of bacteria, so this substance inevitably does damage) and for altering the taste of water;
  • Lead and certain heavy metals, in high doses and consumed on a regular basis, can affect the brain and nervous system;
  • Pesticides, herbicides and metabolites that end up in significant quantities in our tap and bottled water ;
  • 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 water bottle filters out bacteria, parasites and viruses to over 99.98%. You'll also be protected against Turista.

Does the ÖKO filter filter mineral salts and trace elements (limestone, magnesium, potassium, sodium, etc.)?

No, the filter does not filter mineral salts or trace elements (dissolved salts). 
If you own a TDS (Total Dissolved Solids) meter, which measures the quantity of minerals (conductors) present in water, you should find the same measurement before and after filtration with ÖKO. This device costs from €5 to €30 online.

How many liters can I make with an ÖKO filter?

It all depends on the water being filtered, just like every other filter on the market. 

If you filter mud, the pores will logically and mechanically clog up faster. 

 400 L: For the majority of our users who filter at home and on the move (office, school, sports, airport, service station, friends' homes, etc.). 
 - The water in our taps, where most of the contaminants harmful to our bodies are concentrated (chlorine, pesticides and metabolites, PFAS, heavy metals, drug residues, fluoride and sometimes E.Coli bacteria when filtration plants go haywire following violent storms or malfunctions). 
 - The kind that springs from griffins in the wild. 

DISCLAIMER: water that's clear to the naked eye doesn't mean it's not contaminated, because contaminants that are harmful to our health are INVISIBLE to the naked eye. So pores, also invisible to the naked eye, may become clogged more quickly. 

 200 L to 400 L: For hikers, trekkers and travelers who go hiking and trekking. 
 - Water from rivers, lakes and streams. 
It all depends on the water you'll be filtering. 
If it's charged (and this can be invisible to the naked eye), cloudy and/or muddy, the pores will clog up faster. 
It's mechanical, and you'll feel it when you apply harder pressure. 
The filter's strength lies in its ability to filter out viruses, bacteria and protozoa, also invisible to the naked eye, which can make us ill. 

 10 L to 200 L: For hikers, trekkers and travelers who go hiking and trekking.
 - Stagnant water (puddles, mud, etc.). 
If you have a choice: Filter the clearest, most running water possible. 
If you don't have a choice: filter puddles and muddy water. At least you won't get sick, but the filter's lifespan will diminish irreparably. 

MORAL: there are billions of types of "filterable" water, and it all depends on the composition of the water you'll be filtering. Be responsible, because only you can decently know the water you're filtering.

Application to manage the filtration of your ÖKO water bottles

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

It's a "simple" counter that lets you create your bottles (the number of fills varies according to the container) and increment the number of fills according to the type of water you're filtering. It's a reminder.


If you know your daily consumption, you can also set a reminder in your diary.


In any case, when the filter comes to the end of its life, you'll feel it with the harder pressure and the return of a different taste (chlorine may return slightly). Then it's time for a change.

Does the filter have an expiration date?

No, the membrane is embedded with antibacterial ions around the pores, which prevent proliferation and decayAs long as you haven't made up the correct number of liters for each type of filtered water, you can use it. 

If you're not going to be using it for several weeks or months: keep the filter dry and away from light. 

As soon as you use it again: Iron 1L to reactivate the charge fields and remove any dust from storage.

Can I drink seawater with an ÖKO filter?

NoÖKO filters are designed to filter freshwater ONLY. 
Seawater contains too many mineral salts and irreparably damages filtration quality. 

If you have a softener with salt addition, we strongly advise against using ÖKO, as the amount of salt will irreparably damage filtration quality. 

If you have a mechanical softener without adding salt, no problem, you can filter with ÖKO.

When I travel abroad, what does ÖKO recommend?

CARRY at least 1 spare filter, if not 2. 

Why should you? Because you don't know in advance the quality of the water you'll be filtering. 

Especially in countries where water treatment is questionable. Your filter may clog more quickly. 

This is a recommendation, not an obligation. 

We know that the cost of a filter is derisory compared to the price of the overall trip. 

If you plan to hike or trek in foreign countries, a SWIG survival straw is also recommended. 

Available in the Filters & Accessories menu.

Can the ÖKO water bottle be stored in the fridge?

Yes, that's no problem at all.

The recommended temperature range is 5 to 60 degrees Celsius. The filter flask should not be placed in the freezer. If the temperature drops below 0 degrees, the water in the filter could freeze, expand and potentially damage the pores of the filter membrane, reducing its efficiency.

Can I fly with the ÖKO flask?

Yespassing it VACUUM control. 
Then you fill it up at the airport toilet sink. You'll save a lot of money by avoiding expensive PET1 plastic water bottles, full of microplastics (and other contaminants). Not to mention plastic pollution.

Can I filter fruit juice, cola, coffee, vitamin supplements and tea with the ÖKO filter?

No, only GENTLE water . The water passing through the filter MUST be soft water.


There are videos on the Net of us filtering Coke, Fanta and even urine!

Why?

Filtration is instantaneous, as the water passes through the filter. 

Let's put some water in and say : trust us, ÖKO is a powerful filter!

You'd be hard-pressed to take our word for it, and so you should.


These are just examples, so that you can see for yourself that ÖKO filters instantly, because it's VISUAL.

 

Do not reproduce, or your filter will be irreparably damaged.

Is the water bottle compatible with a bicycle bottle holder?

Yes, but only for the 650 mL model. 

It's best to use a Z-shaped holder to prevent the bottle from rattling, as it's thinner in the center for a better grip. 

If required, our customer service department can send you a photo of an ideal model. 

Alternatively, you can attach the water bottle to your handlebars with a bracket, easily found in sports stores or online.
