G2T-ICE is a natural personal cooling device. Needless of the coolant and compressor, the air cooler uses only water and proprietary heat absorption cooling filter to achieve most efficient cooling effect. <br><br> The cooling filter is made from particular fibers to absorb largest amount of water within short period of time and enables G2T-ICE intensive evaporation with smallest filter size. <br><br> The friction of gaseous water molecules in the cooling filter creates anions (OH ion) in the air; this is the most natural way to generate anion. It's suggested to replace new filter for every 3 months. <br><br> Package includes: <br> <br> -Personal Mini Air Cooler <br> -Micro USB Cable <br> -Evaporation Cartridge(Cooling Filter)/Nano Sliver yarns <br> -Notice card & User Manual
