In 1933, Vent-A-Hood literally invented the residential range hood. Vent-A-Hood has spent every year since then improving upon the concept. In fact, the internal design of Vent-A-Hood's ventilation system has earned a U.S. patent, an achievement no doubt possible because of their single-focus types. Vent-A-Hood concentrates only on range hoods. Their engineers do not divide their time on designs for refrigerators, ranges, toasters, or cute oven mitts. The driving philosophy – the only philosophy–is that the air in your home should be fresh and pure. No other range hood can offer you a quieter, safer, or more efficient system for removing odors and smoke as Vent-A-Hood.
