In May, Whirlpool is introducing a new line of microwave hood combination ovens. The products deliver cooking and ventilation performance with easy-to-use features. The microwave hood combination oven delivers an industry-first fan sensor to ensure smoke, heat and steam are effectively removed. Automatically sensing cooktop heat, the four-speed, 400 CFM fan adjusts to the right amount of ventilation power. Additionally, the fan's filter is easy to maintain and may be cleaned in the dishwasher.
