The organic waste caddy has been carefully designed to help reduce odors from collected waste. With its unique ventilated design, it allows air to enter and circulate inside the caddy, helping to reduce moisture—the main cause of unpleasant odors from decomposing food. The Stack 4 features a replaceable odor filter in the lid that works together with fresh air to help capture any smells that may occur. It has an easy-to-clean polypropylene body, a flip-top lid, and a sturdy stainless-steel carrying handle.
