ÖKO Level-1 filter is carbon based and it is designed to effectively reduce present chlorine, taste and odor while providing crisp and clean tap water. This filter emits the fastest water flow with effective filtration.
ÖKO Level-2 filtration, originally developed through a NASA grant for space stations, is now available for consumer use. 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 1micron each to virtually close the pore to any intruding agents. Using built-in silver ions, the material then kills bacteria upon contact. ÖKO 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.
