Refers to a range hood designed to be installed under a cabinet.
In the past these were among the least expensive types (compared to island-mount and wall-mount range hood types), however in many new kitchen configurations, there are 30″ to 60″ fully ducted, undercabinet hoods. The economy undercabinet hoods suffer from several disadvantages: their small formfactor limits blower power and duct size; design impact is minimal or nonexistent; hood dimensions typically need to match the cabinetry, limiting choices.
