Are recirculating hoods any good?

Recirculation/self-circulating cooker hoods are often much cheaper than extraction hoods because they don't include ducting. However, they are less effective at dealing with smells, grease, and smoke because they have to process the air, and inevitably they don't do that 100% perfectly.

Do ductless range hoods remove smoke?

A ductless (or ventless) range hood does not vent out of the home, instead, it carries the debris and smoke form the air and filters it through a charcoal or carbon filter before releasing it back into the room. While many times this method is not as functional as a vented hood, it does work.

How do you tell if you have a ducted or ductless range hood?

It's possible, though, that the range hood is vented straight through the wall to the outside. To tell if that's the case, go outside and look at the wall to see if there's a wall cap to allow the vented air to escape. Of course, if the range hood isn't mounted on an outside wall, it probably wont' be vented like this.

How powerful should my range hood be?

To power your range hood, you need at least 100 CFM for every 10,000 BTUs of your stovetop. For example, a 100,000 BTU stove needs at least a 1000 CFM range hood. For electric stoves, multiply the stove width by 10. So, for a 42” electric stove you want a range hood with at least 420 CFM.
