The research report of the Shamir Medical Center research team led by Professor Shay Efrati of Tel Aviv University in Israel is about mask-type oxygen inhalation, with an oxygen concentration of 100% pure oxygen. Most of the micro-hyperbaric oxygen chambers produced for civilian or home use nasal inhalation or earphone-type oxygen inhalation, which may mix with the air in the cabin during oxygen inhalation, so that the oxygen concentration cannot be reached and the anti-aging effect is affected. The home-use micro-enriched hyperbaric oxygen chamber developed by our company's R&D team uses mask-type oxygen inhalation, and the oxygen concentration can reach 91% to 95%, which can maximize the intake of oxygen concentration and achieve the anti-aging effect.
