description:

The simplehuman charcoal filter naturally absorbs odours. After extended use, the filter's odour 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 where there are odours, such as the underside of your bin lid or inside a cabinet door. Each pack contains 2 charcoal filters.
