Broan. The Evolution Series of undercabinet rangehoods includes products to meet any budget. Each of the three available models can filter up to 40% larger particles than other rangehoods. A sloped bottom design funnels smoke into the filters. Smooth surfaces, a fully enclosed bottom, and dishwasher-safe filters help reduce maintenance. Evolution QP1, QP2, and QP3 models are all available in 30-, 36-, or 42-inch widths, in several finishes. 800.558.1711.
