• ÖKO Odyssey 6 in 1 Bottle


ÖKO takes the concept of eco-friendly water container one step further by adding NASA derived filtration technology to it's smartly designed, super-light and high-tech bottles.  

The bottle cap is made of Tritan, which is a BPA free clear hard plastic well known for its durability and clarity, the clever part of these OKO bottles are in the way the user can actually see the amazing filter work whilst drinking or pouring from the bottle! 

The OKO bottle is made from an ultra light polypropylene material, The semi-soft nozzle and washer create functional accents whilst the ergonomic contoured shape makes the bottle very easy to grip. 

Each bottle comes complete with an o-ring carabineer, this makes the bottle very versatile as it can easily be carried or hooked onto a rucksack. 

OKO level 2 filtration was originally developed through a NASA grant for space stations, this has now been made available for consumer use. Quite simply put, it is state of the art space station water filtration technology, In your very own water bottle!! 

The OKO filter produces highly efficient filtration with a powerful flow. The sophisticated upstream valve returns any backwashed fluid into the "unfiltered" part of the bottle for re-filtration, this ensures that every single particle of fluid that passes through the drinking nozzle is completely pure, fresh and clean to drink.

ÖKO Level-2 filter, originally developed through for NASA space stations, is now available for consumer use. t is the state-of-the-art in water filtration technology.

Charge fields, activated upon water contact extend 1micron each to virtually close the pore to any intruding agents.

How do I use my OKO bottle?

Simply unscrew the cap, fill the bottle as normal with water, ensure that you replace the filter and cap correctly, lift the nozzle and drink as normal, the filter does all the work instantly, you don't even need to wait!

The first time you use a new filter, you will need to fill the bottle to the top and then pour about ½ of the bottle away, through the filter. You may see a darkening to the initial water, this is just harmless carbon residue and not dirty water.

How long will each filter last?

You can expect to get approx 375 refills from the 1L bottle and 580 refills from the 650ml bottle

How do I clean my OKO bottle?

OKO bottles are dishwasher safe and easy to clean. However, please note the filters are NOT dishwasher safe and should not require any cleaning. Each bottle comes complere with its own care instructions.

How do I know if I have a level 1 or 2 filter?

If you purchased your bottle in January 2013 onwards, check the colour of the silicone ring ontop of the filter, if its red then its a level 1, if its clear then its a level 2. If you are unsure then you can contact us and we can help you with it.

Can I drink juice, tea or coffee through the filter?

The filter is only desinged to be used to filter and drink water, if you choose to drink other fluids through the filter it can permanently damage the filter. We recommend removing the filter to drink anything other than water.
