How does a range hood work?
Through its fan, a range hood works by acting as a ventilation system that helps reduce fumes, smoke and odors in your kitchen as you cook. While some range hoods work by drawing air to the outdoors, recirculating hoods use a series of filters to scrub the air before returning it to the room.
To get the most out of your range hood, running the hood fan for a few minutes before cooking can help create suction and prevent delays in venting. After cooking, running the fan again for several minutes can help you clear lingering smoke and odor from the air. If you opt for a ductless range hood that recirculates air, ensure the filter is cleaned on a regular basis for optimal use.
