Abstract
A filter for absorbing ethylene gas and moisture and emitting carbon dioxide that can be removably coupled to a container. The container can have vent openings to allow air to circulate to prevent excess condensation, or the container can be any type of flexible, semirigid, or rigid produce container such as a plastic bag, a refrigerator or a typical plastic container. The contents of the filter are in vapor contact with the internal environment of the container such that it can absorb ethylene gas and moisture in the container and release carbon dioxide into the container to retard the ripening process of the produce stored in the container.
