X4Oxygen are pressure chambers for hyperbaric oxygen therapy. These are particularly characterized by the high quality of the materials chosen and the outstanding workmanship. In addition, when using X4Oxygen, a particularly high oxygen content of 65% can be provided, which represents a more than twofold increase in oxygen content compared to previous pressure chambers! X4Oxygen exceeds the highest quality standards and, thanks to its predominantly German inventory and a two-year warranty, offers the opportunity to generally publish HBOT applications and to enable many people to enjoy the application, which has been tried and tested for decades, and thereby benefit from the effects that occur to benefit. HBOT is a huge advance thanks to scientific research. X4Oxygen could bring enormous benefits to human well-being and physical health.
