Island cooktops do not need to vented and exhausted unless required by local building codes. A downdraft cooktop is designed with a grate to suck smoke and grease down, and to the outside through a crawl space, instead of out of the air.

The truth is that you should consider a vent for your electric stove. Even if you cook one or two times a week, a vent hood can be beneficial for you. It will clean your indoor air and improve your indoor air quality. For electric stoves, we recommend a range hood of at least 600 CFM.

An island range hood is a beautiful statement piece for your home. It keeps your kitchen air clean and fresh while making cooking easier. Unlike a wall or under cabinet hood, it doesn’t take up space on your wall. So, you’ll have more room for cabinets, windows, or whatever else you might want to put in your kitchen.

How They Work. Downdraft vents work by pulling the air across the cooking surface and drawing smoke, steam and grease down through a filter and into a duct that carries it beneath the floor or along the cabinet kick space and outside your home.

If your stove is near an exterior wall, the fastest way is to go through the wall. Other vents have to go up through the roof. If your home has a chimney, you can often connect the vent pipe to the chimney instead of creating another hole in an exterior wall.

10 Things to Do If You Don’t Have a Range Hood or Vent

1. Use a window fan.
2. Use a portable HEPA air filter.
3. Use a fan in another room, like the bathroom.
4. Get a grease splatter guard.
5. Wipe down your kitchen cabinets frequently.
6. If you paint your kitchen, use a satin or semi-gloss finish, or choose scrubbable paint.

Some stoves come with built-in downdraft vents that rise up from the back or center of the cooktop when a burner is lit. Like updraft hoods, downdraft units must be vented to the outdoors or they are ineffective. On a gas stove, a malfunctioning downdraft vent can allow dangerous carbon monoxide to remain in the air.

Range hoods do not have to be vented to the outside. But, ducted range hoods are almost always preferred over ductless hoods. They remove all the smoke and cooking exhaust from your kitchen, while ductless hoods recirculate your cooking exhaust back into your kitchen.
