OKO Replacement Filters

Oko Replacement filters for the AlkaWay ÖKO Water Bottle, for both the 650ml and 1000ml versions.

Originally developed for NASA and used in the ISS (International Space Station). We convert the material for consumer use in our bottles. Simply put, it is the state-of-the-art in water filtration technology.

In addition to a 2-micron pore size, the material utilizes a positively charged electro-adsorption (attraction and retention) process to draw and trap harmful agents much smaller than its pore size. Charge fields, activated upon water contact extend 1 micron each to virtually close the pore to any intruding agents. The OKO Replacement Filter level-2 filter lab tests using NSF/ANSI Standard 53 reflect 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 international water sources. A stack of over 400 such pores in the 0.8mm thickness of the filter creates a “tortuous path” which a harmful agent would have to travel through in order to make it across the filter membrane.

  15. Your service was really good. You made up for the rubbish service provided by fastway couriers who couldn’t be bothered to deliver the filters. Thanks for sending a second set out by Aus post that did get to me! thanks
