For some reason one of my bathrooms smells strongly of mold. I've read that using charcoal helps - and it really does. I also bought one for my kitchen. They sell the charcoal in cloth bags, which probably look more finished than these mesh bags, but I think the cloth leaves black dust when hung on the door. They do shed some dust but I put them in clear acrylic tubs and they look and work great. They have zippers so they can be easily refilled.
