ABSTRACT:
Apparatus and methods for removing malodor from the air, particularly from confined spaces are disclosed. Such devices and methods are useful for example for storing and preserving food in closed compartments such as refrigerators. The apparatus and methods utilize baking soda as the odor removing substance, either alone, or in combination with another odor removing substance, which may include activated carbon. In one embodiment, the apparatus has a detachable cartridge member which contains baking soda. In one version of this embodiment, the detachable cartridge member is used with an air moving member that draws air through the detachable cartridge member. In one embodiment, the method involves using a detachable cartridge member with an air moving member in one confined space, and using another cartridge member without the air moving member in another compartment of the confined space. In another embodiment, may also be used for emitting a scent, or other substance (including, but not limited to insecticides, air fresheners, deodorants, aromacology, aromatherapy, or any other odor that acts to condition, modify, or otherwise charge the atmosphere or to modify the environment) into the air.
