A Pacific Range hood draws in smoke, heat, grease and odors produced during cooking and prevents buildup of these materials in the home. Ducted hoods push the air out of the room completely, while duct-free hoods can only filter and recirculate air.
Pacific Range hoods feature two main components: a light and a fan. The light is designed to provide additional brightness to the cooktop area, with different models containing different styles and wattages of light bulbs. The fan component conducts the majority of the hood's functions by pulling in air from above the stovetop. In a ducted hood, the fan is connected to a ventilation system that either feeds into the home's main ductwork or serves as a direct pathway out of the home. In either scenario, the fan pulls the air and contaminates produced during the cooking process up into the hood and passes them safely out of the home.
With a duct-free hood, there is no connection to the outside of the home; instead, there is a filtering system located behind the fan. This filter traps the dust, odors and grease that form during cooking, but does not do anything to remove heat or humidity from the room.
