An assembly for removing odors from items having a first container formed fromamaterial that is at least partially ozone impervious and that defines a firstinterior that isaccessible via a selectively closeable opening, an ozone generator that isadapted to generate andexpel ozone gas from the ozone generator into the first interior of the firstcontainer, and afastening mechanism for selectively maintaining the selectively closeableopening in a closedorientation in which the fastening mechanism prevents access to the firstinterior. In variousembodiments, when the selectively closeable opening is in the closedorientation and the ozonegenerator expels ozone into the first interior of the first container, theozone concentration in thefirst interior is at a concentration of between 1 ppm and 2000 ppm and theozone leakage fromthe first container is between 0.01 ppm and 0.03 ppm of ozone.
