All OTR microwave ovens can be set up to either allow the fan to recirculate the air back into the kitchen or be vented to the outdoors.
Do all over the range microwaves need to be vented?Not all over the range microwaves vent outside, but ducted applications do. Venting a microwave outside is usually considered an upgrade because it's the best option to getting rid of airborne smoke, steam and grease.
Do you have to vent a microwave hood combination?Many microwave hood combinations come factory set to vent via air recirculation, meaning they filter the air then push it back out into the kitchen. Other types of hoods that vent externally require ductwork in the wall, ceiling or floor. If you don't have ductwork already, you'll need a professional to install it.
