Description

ÖKO The combines water filtration technology that was originally designed for use in NASA ISS (International Space Station). It’s an elegant bottle design made of 100% FDA compliant materials. This combination gives us a unique filtration bottle: lightweight, versatile and able to deliver the very highest quality water from innumerable water sources in over 140 countries.

It has a filter capacity of 580 refills (100 Gallon or 380 litres). The ÖKO level-2 filter (included with every bottle), has been lab tested to remove 99.9999% of Giardia Lamblia & Cryptosporidium, two of the most common contaminants found in water worldwide.
ÖKO bottles may also be used with other filtration levels (sold separately).

Bottles:

It’s a patented bottle design made from a customized blend of plastics. It has passed stringent SGS testing for FDA food contact safety.
Even the bottle cap is made of Tritan®, a BPA-free clear hard plastic renowned for its durability and clarity, so you can see water filtration in action.
The bottle’s body is made of an ultra-light polypropylene material commonly used in food storage containers. It has a high-temperature resistance, so it does not leach chemicals or smell when exposed to warmer temperatures.

Our semi-soft nozzle and washer create functional accents and the contoured shape makes the bottle easy to grip. The Ö-ring carabiner is used to carry or hook the bottle onto a bag

Here at AlkaWay, we have a long, long history of searching the world for the best and the safest water bottle for travellers.

Many years ago I spent 2 weeks in a Nepalese hospital with Dysentery from water, and I would never wish that experience on anyone. I dropped 20 kg.
If I had this technology then…

Because filtration technology is always getting better, we never stop looking. We’ve been watching this filter technology for about 8 years. It originally came from Scandinavia and was ridiculously expensive. Today, it’s made in the USA, has come down in costs, and we have already been installing systems for the whole of house and benchtop filters where absolute water safety is demanded. The original inventors call it medical grade water filtration, and they are right.. but for me, it’s important because it gets over the old problem all high-performance filters have had. OKO flows easily AND filters finely at the same time. And in the heat of Rajasthan or the wilds of Namibia, that is BIG.

This is the biggest breakthrough in water filtration that I’ve seen in the last 18 years, especially in its ability to exclude the traveller’s nemesis, parasites, cysts, bacteria, and viruses. They’re the little beggars that will bring your dream holiday to a sudden end. And that, dear friends, isn’t made any better by expensive travel insurance. As far as I’m concerned, the least expensive, most effective ‘travel insurance’ is a good water filter bottle AND a spare filter just in case!

ÖKO Filters & How They Work:

We’ve chosen to equip all Bottles to come Equipped With our ÖKO Level-2 advanced Filter.

Our choice, ÖKO Level-2 filtration, was originally developed for NASA and used in the ISS (International Space Station). We adapted this technology for consumer use in our bottles. From our perspective and experience, it’s the state-of-the-art in water filtration technology. There is no portable water filter like it in the world.

A 2-micron pore size means fast flow.  The ÖKO media utilizes a positively charged electro-adsorption (attraction and retention) process. This draws and traps harmful agents far, far smaller than its pore size. Charge fields, activated upon water contact extend into the 2-micron gap between them to virtually close the pore to any intruding agents.

ÖKO level-2 filter lab tests show the removal of 99.994% of e-coli, 99.9999% of Cryptosporidium and Giardia Lamblia, the most commonly found bacteria and microorganisms in lakes, streams and less ‘managed’ water sources in many less developed countries. Here’s A stack of over 400 such pores in the 0.8mm thickness of the filter creating a “tortuous path” which a harmful agent would have to travel through in order to make it across the filter membrane.

To check what level of filtration is recommended while travelling in different countries worldwide, see the ÖKO ON THE GO Chart. The OKO filter bottle provides protection at L1 and L2 level, but not for water supplies listed at L3 or ATR level.

    I don’t think my requirements for a water bottle are all that extreme, but it’s taken 6 years for me to find one that I like. And not only do I like it, but I use it ALL the time.

    All I wanted was one that filters the greebly stuff out of the water.

    If it has to be plastic then it MUST be BPA free. I really like my stainless-steel ones, but after a day of carrying one around, it gets a bit heavy.

    The water has to be easy to get out of the bottle. A good flow rate I guess you call it. After all, what’s the point of having a filter bottle if you end up ripping the lid off to get to the water before you die of thirst.

    And it has to fit in the cup holder in my car.

    Finally, I found one that has all of the above. My new OKO water bottle does all of this. Love it.

    Great product. I have happily purchased a few different products from Alkaway over the last few years & will continue to do so.
