What is an over-the-range microwave vent?
An over-the-range microwave vent is a kitchen appliance that combines the functionality of a microwave oven with a built-in ventilation system. This design allows the microwave to be installed above the range or cooktop, saving valuable counter space while serving dual purposes: cooking food and venting smoke, steam, and odors generated during cooking.
The ventilation system typically includes a fan that can either filter the air before recirculating it back into the kitchen or vent it outside through ductwork. This feature is particularly beneficial in smaller kitchens where space is limited and proper ventilation is necessary for maintaining a comfortable cooking environment.
How does the venting system in an over-the-range microwave work?
The venting system in an over-the-range microwave typically features a fan that draws in air from the cooking area.
