An assembly for removing odors from items having a first container formed from a material that is at least partially ozone impervious and that defines a first interior that is accessible via a selectively closeable opening, an ozone generator that is adapted to generate and expel ozone gas from the ozone generator into the first interior of the first container, and a fastening mechanism for selectively maintaining the selectively closeable opening in a closed orientation in which the fastening mechanism prevents access to the first interior. In various embodiments, when the selectively closeable opening is in the closed orientation and the ozone generator expels ozone into the first interior of the first container, the ozone concentration in the first interior is at a concentration of between 1 ppm and 2000 ppm and the ozone leakage from the first container is between 0.01 ppm and 0.03 ppm of ozone.
