An odor removal assembly comprising a container that, when open, allows a user to place items into the bag's interior, and when closed, prevents a user from placing items into the interior of the bag. The container may include a fastening mechanism for closing the container. The assembly includes an ozone generator that generates ozone and expels the ozone through a conduit that extends between an outlet of the ozone generator and the interior of the container. The assembly may also include second container configured for placement within the first container. In such embodiments, a user may utilize a portable bag for use with the odor removal assembly without having to carry around the actual ozone generator. Rather, the user may insert the second container into the first in order to utilize the odor removal assembly.
