charcoal filters?

I don't know about the ones you plug in. But, better idea - I found the perfect product that I've used for years and know dozens of other people that use it. It is a product called FRIDGE IT carbon odor absorbers. It is a little purple cube with an incredible activated carbon filter inside that is really, really, great. The carbon literally absorbs and eliminates the odors and works for a long time. It works so much better than all those sprays, plug ins and fragrances that just cover up smells and doesn't get rid of them. Also, alot of sprays have warning statements about being eye irritant. and gels and oils that say keep away from fabric, etc. and just don't eliminate odors. Just put a couple of these in your closet hanging from a hanger or even in drawers. . I use this product everywhere including car(smoke and pet smells), storage, closets, my fridge and also under sinks, near trash and have friends that use it on cat litter box and also diaper pails - it's that good. I really recommend it. You can buy it in kitchen gadget sections in stores like walmart and linens and things. I also think camping world sells it. Definitely worth trying
