Cooker Hoods It is important for the cooker hood to be slightly wider than the hob below it. Only then can you be certain of capturing all the rising steam and vapours and benefit fully from the cooker hood's power. If there is not enough space for this, then the cooker hood should be at least as wide as the hob.
How wide should vent hood?
Measure the width of the area over the range or cooktop. Range hoods often come in 24", 30" or 36" widths. The hood should be at least as wide as the cooking surface, but preferably should be 6" wider.
How do you size a kitchen extractor fan?
To find the fan needed for your size kitchen, multiply the number of cubic feet in the room by the number of air exchanges (15), then divide by the number of minutes in an hour (60).
How much space do you need between hob and extractor?
Manufacturer recommendations vary but most agree that the minimum distance between the hob and the lowest part of the extractor hood should be somewhere in the 650-750mm range. We also recommend checking the height of your ceiling as this may change the total distance.
How do I know what size extractor fan I need?
The rule of thumb is that you need at least 1 CFM per square foot of room area. To determine the square footage of your bathroom, multiply the length times the width. For example, if your bathroom is 6 feet wide and 9 feet long, its square footage is 54. Therefore, it should have a fan rated for at least 54 CFM.

To power your range hood, you need at least 100 CFM for every 10,000 BTUs of your stovetop. For example, a 100,000 BTU stove needs at least a 1000 CFM range hood. For electric stoves, multiply the stove width by 10. So, for a 42” electric stove you want a range hood with at least 420 CFM.
Do I need a cooker hood and an extractor fan?

Do cooker hoods have to vent outside?
Range hoods do not have to be vented to the outside. But, ducted range hoods are almost always preferred over ductless hoods. They remove all the smoke and cooking exhaust from your kitchen, while ductless hoods recirculate your cooking exhaust back into your kitchen.
Does an extractor fan have to go outside?

Where does a cooker hood vent to?
Range hoods are vented up through the roof or out through an exterior wall. Look for a metal duct going through the cabinets above or an exhaust cap on the exterior wall behind the range hood. You should feel air being blown out of the exhaust cap on the roof or wall when the fan is running.
