The people damaged most by the high level of oxygen consumption are those who have weaker respiratory function. These are the elderly, children and people suffering from asthma, dry cough or weak bronchi. Of course, smokers are included. The respiratory organ is degenerative organ. The function reaches the highest point during the 20s and become naturally lowered as one gets old. There is no case reported of improvement in respiratory function. People who smoke (or have smoked) fall behind in the competition for oxygen. So do people with weaker breathing due to mental stress despite being in healthy condition, people who experience fatigue in the morning due to hypoxia during sleep in which respiratory function is not stimulated and people who suffer from headache, etc.. We, instead of enjoying lives in urban civilization and culture, suffer from stuffiness and circulate impure air. OXUS intends to create oxygen environment human beings have the right to enjoy and experience. We intend to propose not only the so-called passive plan of generating, therefore supplementing oxygen as much as the amount consumed by users, but also the more active plan of creating oxygen atmosphere of the nature. We have the confidence to say that we are equipped with all the necessary technologies to propose these plans. With passion and effort added to the technological power, OXUS will advance as the world&＃39;s best R&D company specializing in oxygen generation technology.
