The Comfee dehumidifier creates a pleasant indoor climate in smaller rooms. It helps combat mold growth and musty odors in bathrooms, kitchens, or basements. With a dehumidification capacity of 20 liters per day, the water tank's volume of 3 liters is modest. Therefore, if you have more demanding tasks, you should expect to empty the tank accordingly often. The dehumidification performance is generated by a cold compressor, whose refrigerant is safe for health and environmentally friendly. A HEPA filter is not included.
