Unlike ordinary household trash cans, the Diaper Genie system helps keep unpleasant smells where they belong. Our Double-Lock design and 7-layer bag help keep odours from escaping, so your nursery stays new-baby fresh. Diaper Genie Elite now comes with Diaper Genie Carbon Filters to help tackle the strongest diaper odours. These filters are made with safe, natural activated carbon that locks in odour molecules rather than just masking the odour with fragrance.
