As is well known, the negative oxygen ions are called: the 'air vitamin' has important medical health care application value. Around 1985, more than 100 plants produced the product in China, but all had ozone, 11.5.11.1986, Chongqing journal reported the research results of professor Boleke, Camia, university of Columbia, USA: "even small doses of ozone are carcinogenic," shortly thereafter, the chinese negative oxygen ion generator plant almost totally silenced the occult.

In more than ten years, with the increasing environmental awareness of people, especially with the aging population and the worsening environmental pollution, the production and sale of domestic negative oxygen ion generators begin to heat up quietly and rapidly, butIncluding products produced and exported by foreign merchants in China, the ozone-containing water is still an ozone product, and the nominal concentration of negative oxygen ions is only about one tenth of that of the negative oxygen ions in 1985, namely 10⁵/cm³And the market needs ozone-free high-performance negative oxygen ion generator products to fill the blank.

On the other hand, the research on the biological effect of the negative oxygen ions has made great progress, for example, two groups of mice are placed in a big water pool, the mice swim to a plurality of vertical rods arranged in the pool to climb up (seek survival), one group blowing the negative ion wind for a period of time can persist for 4 hours, and the control group can only climb up for 1 hour and fall into the water within 32 minutes; research on carcinogens 'free radicals' in the human body has shown that more than 95% of the carcinogens 'free radicals' in the human body are oxygen "free radicals", i.e. oxygen atoms O which lack one electron⁺，O⁺An electron in the adjacent O can be captured for self stability, so that the electron cannot be balanced like a 'triangle debt', the 'triangle debt in the human body' is used as a evidence (the luck of the sun-day news and the cloud) and the possibility of eliminating the oxygen free radical is generated when negative oxygen ions enter the blood of the human body through the lung of the human body; the research results of the aerospace medicine prove that: air negative ion environment of certain concentration: for mesenchymal brainstem 5 reflecting mouse seed regulation function^-HT, phagocytic rate of macrophages and finger phagocytosisThe immune function indexes such as the number, the serum hemolysin, the number of spleen antigen binding cells and the like all have consistent comprehensive synergistic effect.
