The "air intake device" injects hydrogen into water (Membrane Dissolution). After the surrounding area of the hollow fiber membrane is filled with hydrogen, the de-oxygenated water will be released through the membrane, and at once hydrogen will be absorbed through the pores engineered into the membrane and dissolved into water. This Membrane Dissolution Technology is especially targeted toward medical treatment such as artificial lung planting. To preserve the original taste, water purification process has not been adopted.
