Smart AI technology: Automatically recognizes food waste and begins the composting process without manual operation, saving time and effort. Odorless and quiet: Features a built-in charcoal filter and noise reduction technology, making it odorless and whisper-quiet (20 dB), ideal for use on the kitchen countertop. Green Mode: Food waste is processed at a lower temperature to reduce average food waste emissions per day. As a result, food waste is processed into more nutrient-rich compost. *May result in longer processing times. Compatible with THINKWARE BLUEVENT MUMU Charcoal Refills: Sold separately, the THINKWARE BLUEVENT MUMU MUMU Charcoal Refills are intended to replace the charcoal in the Thinkware BLUEVENT MUMU Smart AI Food Composter charcoal filter. The charcoal refills are designed to eliminate odors during the AI food waste processing. Whisper Quiet: Enjoy quiet composting with minimal noise disturbances at 20dB.
