What is microwave ventilation?
Microwave ventilation refers to the systems and processes that manage the air and moisture produced during microwave cooking. Unlike traditional ovens, microwaves often trap steam and odors, which can create a humid environment in the kitchen. Proper ventilation ensures that this excess moisture and heat is efficiently removed from the cooking area, maintaining a comfortable and safe environment.
Effective ventilation can be achieved through built-in exhaust systems or external venting, which helps to direct steam and odors out of the house. Some microwaves come equipped with recirculating fans or filters that help reduce smoke and odors, but these systems may not be as effective as fully vented options. Understanding these components is essential for choosing the right microwave for your cooking needs.
How do microwaves vent steam and odors?
Microwaves primarily vent through built-in exhaust fans that can be switched on during cooking.
