Abstract
The invention relates to a method of absorbing water vapor and malodor from a cavity, for example a drawer or wardrobe or the inside of a shoe. This is achieved by placement in the cavity of a package permeable to water vapor and retaining a particulate dehumidifying compound, a particulate odor-combating compound, and a filler comprising starch or a starch derivative or cellulose or a cellulose derivative, or which acts as a thickener or gelling agent for the water inside the package.
