This clever food caddy has been carefully designed to help reduce the smell from collected food waste. It has a unique, ventilated design that allows air to enter and circulate inside the caddy, which helps to reduce moisture - the main cause of unpleasant odours from decomposing food.The Stack 4 food caddy features a replaceable odour filter in the lid that works in tandem with the fresh air to help trap any smells that do occur. It has an easy-clean polypropylene body, a flip-top lid and a sturdy stainless steel carry handle. A liner-retaining hole inside ensures any liners stay in place and the rim of the removable lid hides any untidy bag overhang. Perfect for storing on a kitchen worktop, it is also compatible with our Stack recycling separation system. Custom-fit, compostable liners (IW2) are available separately for the perfect fit. Size: Capacity: 4 litres (1 US gallon). Material: Polypropylene & Stainless Steel.
