Homeowners use them to vent grease and smoke from their kitchen; factories and warehouses use them to vent chemicals and potentially hazardous materials from workspaces or storage areas; restaurants use them to vent heavy grease and smoke out of commercial kitchens.

In restaurants, vent hoods are required. This is what the ICC Mechanical Lawmaking says:
"Blazon I hoods shall be installed where cooking appliances produce grease or smoke as a result of the cooking process."
