Covers: typically waterproof, dustproof, and weather-resistant with windproof drawstring or tightening to stay in place. Kitchen/commercial hoods: described as rust-, heat- and corrosion-resistant with an all-weather design for outdoor or heavy-use environments.
Airflow options listed include about 250 CFM, a 450 CFM high-performance option, and a 750 CFM model. Fan controls are commonly three-speed settings to adjust ventilation power.
Common mounting types include under-cabinet and wall-mount installations. Some listings note a universal wall-mount design suitable for retrofit projects or new builds.
These hoods use baffle-style (U-shaped or aluminum) filters. Filters are reusable and many listings state they are dishwasher-safe or safe on the dishwasher’s top rack for cleaning.
Several models are convertible between ducted and ductless (recirculation) operation. Mentioned vent sizes include a 6-inch round vent for ducted installs and compatibility notes referencing standard 5-inch ducts on some listings; charcoal/activated-carbon filters for recirculation are noted as sold separately for certain models.
