ÖKO is used as much by sports enthusiasts, travelers and hikers as it is by everyday workers, families and even pets!

It is used for mains water (tap water ) in town and country, but also for water from natural sources such as rivers, lakes or puddles, in over 120 countries.

Check the effectiveness of ÖKO according to your country of residence and your environment (urban/rural) by consulting our ÖKO filter page.

As soon as you receive it, fill it 2 times and empty it the same number of times to "wet" the filter and make it fully operational (a greyish liquid may come out during this process).

1. Unscrew the cap (the filter is screwed to the cap, so it's easy to unscrew it for future replacement).
2. Fill your water bottle with water (tap, river, lake, stream, water fountain in companies, water carafe in restaurants, etc.).
3. Screw cap back on
4. Pull on the pipette (the 2 lines must be visible)
5. Apply gentle pressure to the gourd to force the water through the filter and out through the pipette.

The UPSTREAM anti-backflow valve means there's no danger of back flow (unlike non-direct-flow filtration systems, which are breeding grounds for bacteria). Even in the event of backflow, since the filter only lets through purified water, there's no danger to our health. A reassuring double protection.

Every 400 liters on average, depending on the quality of the filtered water.
So, either the flow of filtered water diminishes (sometimes even stopping altogether if you've been using your flask mainly with natural water sources).
Or the bad taste of tap water (especially chlorine) returns.

And if the filter has reached the end of its life and you're waiting for your replacement filter to arrive, don't panic, because the antibacterial ions built into the filter continue to work, so you're safe from germs. But you should know that you can store filters at home, without any deadline before using them:).

Our bottle has been designed for filtering and drinking water.

You can use the bottle without the filter to drink fruit juice or your favorite beverage, but it is not recommended for hot drinks.

Be sure to rinse the bottle thoroughly before using it again with the filter. Sugar, salt and other substances found in juices, teas and soft drinks will quickly and permanently damage the filter.
Thanks to ÖKO's direct flow system, you can use the water filtered by the bottle to make your own tea or coffee. So you can enjoy all the benefits of ÖKO, without damaging the filter!

Depending on how hot your dishwasher is, the SANS LE FILTRE bottle may be dishwasher-safe.

NOTE: The filter is maintenance-free!

The filter is not dishwasher-safe and will be permanently damaged if placed in a dishwasher. Unlike basic carbon filters, the ÖKO filter is made from a highly sensitive, high-performance material. Immersing the filter in harsh or soapy detergents or hot water will not only close the pores and reduce the filter's performance, but will also permanently damage its functions.

For instant filtration and direct flow (without suction, so you can prepare the water for your coffee or tea, for example), you need a flexible body, because it's the pressure that sends the water through the filter and out the spout.

To achieve this, we have chosen the world's most environmentally-friendly and recycled plastic: polypropylene (PP5).
This food-grade plastic is odorless and light to carry.
No BPA, phthalates or harmful agents.
The bottle also has a very long life. You no longer need to buy bottled water.

Once the filter has done its job, simply separate the membrane from its PP5 receptacle, place the^1st in the refuse bin and the^2nd in the yellow garbage can for recycling.

More efficient than a simple activated carbon filter, the ÖKO filter features two filtration levels:

Mechanical filtration down to the micron

• Eliminates chlorine (bad taste)
• Neutralizes unpleasant water odours

Nanotechnology filtration

Eliminates :

• E-coli bacteria (turista)
• Giardia Lamblia protozoa
• Cryptosporidium-type parasites
• Viruses such as poliovirus, norovirus, rotavirus, etc.
• Organic materials
• Plastic micro-molecules (BPA, phthalates, etc.)
• Herbicides/fungicides (glyphosate, etc.)
• The majority of pesticides, limescale, heavy metals (lead, etc.), drug residues, etc., are eliminated.

To ensure that the water leaving the filter is of the highest quality, ÖKO has focused its analyses on all the most dangerous substances that can be found in any water source.

No!

Thanks to the UPSTREAM anti-backflow valve, there's no danger of backflow (unlike non-direct-flow filtration systems, which are breeding grounds for bacteria). Even if there were a backflow, as the filter only lets through purified water, there's no danger to our health. A reassuring double protection.

ÖKO filters water from over 120 countries, in both urban and rural areas.
You can consult the list on our ÖKO filter page.

Meeting the stringent standards of the FDA (Food and Drug Administration) and the NSF (National Science Foundation), the ÖKO Gourd is not only powerful on paper:

More than 140 water samples taken from springs and lakes around the world have demonstrated its effectiveness in filtering micro-organisms from water.

The ÖKO filter is made of spun glass fibers with embedded carbon (1 g / 500^m2).

Its pores, calibrated at 2 microns each, are also surrounded by electro-adsorbent technology that attracts all contaminants (much smaller than a micron) thanks to antibacterial ions.

The result is close to perfection, thanks to this technology and its electro-adsorption process, which makes the ÖKO filter undoubtedly the most practical and powerful filter ever made available to the general public.

Detailed information on how our filter works can be found on the ÖKO filter page.

The filter has a service life of 350-400 L with clear, low-sediment water, which equates to around 600 fillings.

Of course, it all depends on the quality of the water you're filtering. For example, if you drink 1 L of tap water a day with the water bottle, the filter will last about 1 year.

Yes, ÖKO is an official NASA spin-off (a company using technology directly derived from NASA).

Born in the laboratories of the Johnson Space Center in Houston, the technology was first designed exclusively for astronauts on the ISS (International Space Station), then officially handed over to ÖKO in 2013: the start of a great adventure!

ÖKO EUROPE is the exclusive distributor of the ÖKO brand throughout Europe.

This technology meets the stringent consumer marketing standards of the FDA (for components) and NSF (for water filtration).
