Not only is this not likely to be very affective but it will also add heat to your closet. A carbon filter and exhaust fan will be more affective with odor control and actually reduces the room heat.
This reminds me of the air filters that Sharper Image used to advertise. I think these may be geared more towards really cleaning the air for better breathing (i.e. removing dust, pollen, pet dander, etc) rather than removing strong odors. It looks like it could help, but it would probably be smart to use a carbon filter just in case.
