Replacement Filters

Replacement filters for the AlkaWay ÖKO Level-2 filters were 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. ÖKO 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.
