At the same time, this purifier is one of the fastest ones, producing 16 ounces of clear water within only 15 seconds! An outer cup and an inner cup both from stainless steel make up the system. A threaded filter is attached to the inner cup and to get some clean water you only need to pour it into the outer cup and press in the inner cup. Having performed such simple manipulation, you immediately get the purest water. The ingenious filtration mechanism of the Grayl cup combines three parts. The first is the activated carbon which is ultra-powdered for sifting all impurities. The second is the anti-microbial agent for destroying fungus, bacteria, and mildew. And the third is the standard granulated carbon containing charged ion mesh for eliminating pathogens. Moreover, this purifier will decontaminate your water from many other dangerous contaminants, for example, lead, arsenic, chlorine and sulfur, industrial chemicals, etc. No protozoa and bacteria will get the chance to stay in your water with this device. One filter is enough for purifying forty gallons.
