Why would you need a vent hood ontop a conventional oven vs a convection oven?

A vent hood is typically more important over a conventional oven than a convection oven because conventional ovens can produce more smoke, steam, and odors during cooking, which need to be ventilated for safety and comfort. Convection ovens, with their built-in fans, circulate air more effectively, often resulting in less smoke and odor. However, both types can benefit from a vent hood to ensure proper airflow and maintain a healthy kitchen environment. Ultimately, the choice depends on the specific cooking methods and foods being prepared.
