The present invention relates to a novel material for reducing the ozone content in the air. It is known that Hopcalite, which is a mixture of manganese dioxide and copper oxide, is an efficient ozone removing material. However, Hopcalite is an expensive material and it is not generally available in a wide variety of physical shapes that are sometimes desired. In addition, pure Hopcalite particles are brittle and tend to form an excessive amount of very small sized powdered particles which are not easily used.
