Size, shape, CFM, price? There's alot to consider when you are choosing a rangehood. Take our crash course in kitchen
extraction and you'll be equipped to make a better decision.
The most important role of kitchen ventilation is to remove all the greasy, smoky, steamy, gaseous byproducts that you don't want hanging around in your kitchen. When it comes to the choice of the right range hood, it usually depends on the layout and structure of your kitchen, your local building codes, and your own style preferences.
Wall Mount- This type of rangehood is positioned against a wall over your cooktop. Air is usually ducted to the outside of your house through the wall or roof, although some models offer a recirculation option. Wall canopies are known for their excellent performance.
Island Hood -
If your kitchen has an island cooking area, this type of rangehood is for you.
As well as looking good, an island canopy has excellent extraction abilities.
Air is usually ducted to the outside of your house through the roof, although some
models offer a recirculation option.
Under Cabinet - This type of hood is mounted against the wall but under the cabinet.
It can be exposed, to be a design feature, or built into a cupboard. Some compact canopies offer a recirculation option, for kitchens where ducting to the exterior of the house isn�t possible.
Rangehoods are designed to remove steam, grease and odours from your kitchen to help keep your home healthy,
hygienic and smelling sweet.
Once this dirty air has entered the rangehood, it can do one of two things:
i) Exit to the outside through ducting that connects your rangehood to the exterior of your house. This is the preferred method of air removal.
Ducting is the preferred method of air removal. It is more efficient and quieter.
Ducted rangehoods use aluminium filters to catch large particles of fat and grease before expelling steam and odours to the exterior of the house - either through the wall or roof.
The filters are washable in the dishwasher and regular washing is important to ensure that they don�t inhibit air movement.
The shortest and most direct route to the air exit point will be the most efficient.
ii)Recirculate through charcoal filters, which clean the air before it�s returned to the kitchen. This type of air removal is only used when ducting isn�t possible because of how the kitchen is configured.
Serious home chef
Creative cooks need maximum extraction power, so that they can saut�, chargrill and stir-fry through an ever-growing repertoire of dishes.
Anything involving high heat (steaks and grills); high seasoning (curries, stir-fries); or high potential for odour (salmon and other types of fish) will permeate every room of the house unless you have a powerful rangehood on the job.
RECOMMENDED EXTRACTION POWER - 600CFM+ or 1000m3/h
Average family cook
A family kitchen is seldom at rest. At breakfast time it�s churning out everything from bacon and eggs to incinerated toast. At dinner time, meals range from pungent stir fries to good ol� meat and steamed veges.
When your kitchen is about high productivity and fast turnaround, you can�t skimp on extraction power.
RECOMMENDED EXTRACTION POWER - 500CFM+ or 850m3/h plus
For some people, a kitchen is a just kitchen - not a means of self-expression. Often nothing gets cooked, because you�d rather eat out.
If your cooktop is mostly used for reheating, boiling and steaming, with maybe the occasional dash of high heat frying, you can choose to have a lower level of extraction power. However if you just love the look of a canopy hood, don�t let us stop you!
RECOMMENDED EXTRACTION POWER - 300CFM+ or 500m3/h+
How is rangehood extraction power measured?
Extraction power is measured in cubic metres per hour (m3/hr) or cubic feet per minute (CFM).
CFM is one of the most important specs for a fan. It is a measure of the volume of air being exhausted through your range hood.
More CFM means a more effective range hood vent and a cleaner, safer home for you and your family.
In the Bossino range, extraction power starts at 300CFM and goes right up to 1000 CFM,
so it�s a good idea to check specifications before you make a purchase decision.
Why are some rangehoods noisier than others?
Rangehood noise output is measured in decibels (dB). A higher number indicates more noise.
Sone is a unit of measurement used to describe the amount of noise created by an air-moving appliance, such as a range hood. One sone is described is being as quiet as a refrigerator in a quiet room. Sone�s are the industry standard in ventilation for measuring noise levels. The lower the number, the quieter the noise level.
Flexible ducting can make rangehoods noisier to operate. Whenever possible, choose semi-rigid or rigid ducting.
If flexible ducting can�t be avoided, it should be stretched as tightly as possible.
When air moves, it makes noise. Logically, a higher extraction power will mean more decibels.
How can kitchen size or house layout affect rangehood choice?
Large, open-plan kitchens needs maximum extraction power - or the whole house will know what you�re cooking.
Small, closed-in kitchens can get away with a lower level of extraction power.
If the position of your rangehood will require a long run of ducting, or ducting with more than two bends, choose the highest extraction level you can afford.
