How much is the negative ion air health machine jh-33 1a?

Air negative ions, like sunlight, are indispensable substances for human beings. In the wilderness, seashore, mountain village, waterfall, fountain and other places, due to the low atmosphere, less dust and high temperature, there are many ionized negative ions in the air, and the service life can reach more than 20 minutes; In cities, especially industrial and mining areas, the population is dense, the chimneys are numerous, the smoke and dust increase sharply, and the automobile exhaust pollutes the air, which greatly reduces the number of negative ions, destroys the ecological balance and threatens people's health.

The role of negative ions in human health care has long been proved by medical research. The State Administration of Medical Supplies, the authoritative official management organization of the country, has approved a number of air negative ion health machines, and Zhongke, the highest scientific research institution in China, has also developed negative ion instruments. I understand that ecological negative ions are better. Ecological negative ions are small particle negative ions. Medical proof shows that only small particles of negative ions can easily pass through the blood-brain barrier of human body and play the role of negative ions in medical care. At present, only Jinan Huo Xin Electric Appliance Co., Ltd., a subsidiary of Ai Ou Smith in the United States, has this technology (ecological negative oxygen ion generator based on Senpeptide).
