Are oxygen bars still popular? If you open the oxygen bar what preparation and skills are needed, about how much money is required

Car oxygen bar, that is, car ozone anion generator, the following talk about the ozone and anion ozone common sense: ozone, also known as oxygen, the chemical name O3, with high efficiency sterilization function. After a thunderstorm, the air becomes particularly fresh, which is the cause of the role of oxygen. In a certain concentration, oxygen can be converted to oxygen, and no toxic residue, will not form a secondary pollution. Therefore, it is known as "the cleanest oxidizer and disinfectant". Since 1970, oxygen technology has been widely used in developed countries in Europe and America. At present, the international medical treatment has a variety of uses: such as wards, operating room air disinfection, the use of ozone water for medical instrument disinfection, the use of ozone for dental disease treatment (oral surgery and keep the oral cavity sterile), the use of ozone and radiotherapy combined with the treatment of cancer, drinking ozone water treatment of women's diseases, injection of ozone gas treatment of fistula hemorrhoids, varicose veins and so on. In health care, Japan, Taiwan popular inhalation of strong gas (containing a low concentration of ozone air) to strengthen the body, with ozonized water shower body to kill bacteria and beauty. Now the popular high-tech beauty, in fact, is the application of ozone. Negative ions common sense what is negative air ions? Air is a mixture of many gases, the main components of which are nitrogen, oxygen, carbon dioxide and water vapor. Normally, the various gas molecules in air are stable and neutral, i.e., they are not electrically charged. However, due to natural cosmic rays, ultraviolet rays, and the effects of lightning, wind and waves, plants, etc., they can cause the surrounding air to ionize and produce negative ions, also called negative air ions. Negative air ions are essentially negatively charged air particles. The negative air ions that people usually refer to are negative oxygen ions, which are formed when oxygen molecules in the air combine free electrons. The natural discharge (lightning) phenomenon, photoelectric effect, combustion process, fountains, waves, waterfalls, etc. can make the surrounding air ionization, the formation of positive and negative ions. Advantages of car oxygen bar: ★ light ozone, can be sterilized in the car air facilities, inhibit the breeding of germs and viruses breeding. ★ Negative ions can get rid of dust and smoke in the air inside the car, making the air fresh. ★ Ozone can get rid of moldy smell, smoke, formaldehyde, benzene and other toxic gases emitted by leather paints in the car. ★ Negative ions are known as the vitamins of the air, it can improve the human cardiopulmonary function, promote metabolism, eliminate fatigue, keep the mind awake, and can alleviate the symptoms of motion sickness. ★ No secondary pollution, environmentally safe. ★ Air as raw material, less power consumption, energy saving and environmental protection. ★ Small and exquisite, really a good gift.
