Abstract
Devices and methods for sterilizing an enclosed space using ozone are disclosed herein. Various embodiments of the devices and methods also provide for accelerated degradation of the ozone upon sterilization. In some embodiments, a disclosed sterilization unit includes a first housing defining an ozone generation cavity, an ozone generator disposed within the ozone generation cavity, a second housing defining an ozone degradation cavity, and an ozone degrader disposed within the ozone degradation cavity. The sterilization unit of various embodiments is configured to cycle air between the enclosed space and the ozone generation cavity during an ozone generation cycle to sterilize the enclosed space; similarly, the unit is further configured to cycle air between the enclosed space and the ozone degradation cavity during an ozone degradation cycle to return the air within the enclosed space to safe ozone levels.
