Homeowners who can afford the expense of a large, nearly commercial-style gas range have been using ducted kitchen range hoods (KRHs) for decades now. But with recent statements from US Consumer Product Safety Commission on the potential negative health impacts of pollutants produced by gas stoves, more prospective homeowners will be mindful of the need for ducted KRHs.

Ductless and recirculating products are usually not as effective at removing pollutants from the interior space when compared to ducted KRHs, especially for the high-volume gas stove chef. And while electric stoves produce half the particulates of gas according to U.S. Department of Energy data, they still impact indoor air quality, especially when unvented. This makes the Home Ventilating Institute’s (HVI) and the Association of Home Appliance Manufacturers’ (AHAM) recent research on duct termination fitting (DTF) performance and their impact on the future of KRH ratings well-timed.
