The simplehuman activated carbon filter naturally absorbs odors. After extended use, the filter's odor absorbing ability can be recharged by placing it in direct sunlight. To use, simply peel off the double-sided adhesive tape on the back of the filter and attach to a clean surface area where there are odors, such as the underside of your trash can's lid or inside a cabinet door. Each pack contains 2 carbon filters.
