Soothe cough and cold symptoms while adding moisture to dry environments with the Luma Comfort HCW10B Cool & Warm Mist Humidifier. Featuring both warm and cool mist functions, the HCW10B is a perfect household addition during cold and flu season. With both automatic humidity control and a digital LED display panel, the HCW10B is one of the most advanced humidifiers on the market today. The HCW10B is nearly silent, making it the perfect humidifier for bedrooms, nurseries, living spaces and even offices and work areas. Featuring an easy to clean, removable antibacterial water tank, the Luma Comfort warm/cool mist humidifier can run for up to 40 hours on a single tank. A demineralization cartridge helps soften hard water to prevent scale buildup, and coupled with the low water level indicator, this results in nearly maintenance-free operation. Additional features include a 12 hour timer, dual adjustable mist nozzles and a hidden easy-carry handle.
