KO level-2 filter lab tests reflect removal of 99.94% of e-coli, 99.997% of cryptosporidium and 99.9999% of giardia lamblia, the most commonly found bacteria in water sources.;KO Level-2 filtration, originally developed through a NASA grant for space stations, is now available for consumer use.;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. Using built-in silver ions, the material then kills bacteria upon contact.
