A modern cuisine is a place where many home processes take place: we talk about news or watch TV there, but the most important process in most cases is the process of cooking and eating. A cooking process is almost always accompanied by the release of steam or even smoke, which has a negative impact on the kitchen itself, and on the people who are in it. In order to avoid such exposure, you need to install a hood in the kitchen. The current article will be about how to choose a good kitchen hood for home.
A kitchen vent range hood is a device designed to clean the air in the kitchen from various impurities (steam, combustion products, etc.).
Let’s consider the main characteristics of cooker hood:
1. Types of range hoods by the way of air removal.
There are two main types for this criterion: flow and recirculating (filtering).
- Flow hoods operate on the principle of drainage of contaminated air and connect to the ventilation ducting system.
- Recirculating hoods do not connect to the ventilation duct. There are special hood filters which are installed in such models, so the air returns to a room again. A recirculating model is a convenient option when normal ventilation is absent.
There are also combined hoods which can work in both modes.
Each of these types has its advantages and disadvantages, but it seems that flow hoods are a better option.
First, they have higher performance in most cases, and secondly, they do not require a constant replacement of filters.
It is always recommended to have an anti-return valve in a flow extractor, which passes air into the ventilation shaft and prevents its back motion into the kitchen.
The installation of the hood must be made taking into account this observation.
Comparative drawbacks of flowing hoods include the need for air ducts, which may complicate installation and affect the interior.
2. Hood kind.
It can be said that there are three main forms of hoods depending on their shape and mounting features: flat, dome and built-in.
- Flat hoods are mounted on a wall above a tile or cling to any furniture element. In most cases, these are circular models.
- A dome hood in the kitchen can also be mounted on the wall, in the corner or on the ceiling (island range hoods). Often such models operate in flow mode and they are the most widespread.
- A built-in range hood – in accordance with its name is placed in a special cabinet or niche and can work both as flowing and as circulating.
The choice of kitchen ventilation hood is very much dependent on the features of the interior.
General recommendations can be as follows:
If there is access to the ventilation shaft – buy a dome hood.
If your kitchen is very small or there is no access to ventilation – a flat device is your choice.
If you want a hood to not spoil the interior – you can buy a good built-in hood.
Stainless hoods are the best by material.
3. Hood power and productivity.
The power in this case is an indicator which indicating the amount of air that a hood can miss per unit of time. It measured in cubic meters per hour.
The power of a kitchen hood should correspond to the calculation parameters, otherwise the appliance does not effectively cope with its tasks.
Let’s see how to calculate a hood power.
For this you can use the following formula:
Hood power (cubic meter /hour) = Kitchen area (sq. m.) x Ceiling height (m) x CANU x PR,
Where CANU is a coefficient of air necessary updating per hour.
CANU is 10-12, according to the norms air in the room should be updated 10-12 times per hour.
PR is the power reserve, which must be taken into account to compensate for the various factors of air resistance. The PR can be taken for 1.2 – 1.3 for flow extracts and 1.5-1.7 for circulating.
Here is an example:
If your kitchen has an area of 12 square meters, the height of the ceiling is 3 meters.
So you will need the best powerful range hood with a power of 12 x 3 x 12 x 1.3 = 562 cubic meters/hour.
4. Range hood sizing.
Hood sizes in most cases are standardized in their width.
The width of a hood should equal or exceed the width of an oven above which it is installed.
Modern hoods have, generally, a width of 50 (narrow), 60 or 90 centimeters (19.7, 23.6, 35.4 inch).
It should also be noted that the height of a kitchen stove exhaust hood installing (distance to a stove) should be 60-65 cm for electric plates and 80-85 cm for gas.
5. Additional options.
These additional features include:
- Lighting features. Light can be provided with incandescent lamps, fluorescent, halogen or diode lamps. The most up-to-date LED is considered to be the most efficient and reliable.
- Liquid crystal control display. It helps to adjust the operation of the device comfortably.
- Automatic on/off. The extractor with this functionality can automatically respond to changes in the kitchen air.
- Timer. It turns on/off a hood at a specific time. It can be set to synchronize on/off with another device that has a timer, such as multi-cooker.
- Remote control panel. It helps to manage a device remotely.
Speaking about brands of cooker hoods, it is possible to mention, among other, such firms as FABER, Zephyr and Bosch.
Well, hopefully the article will help you understand how to buy the best range hood for your kitchen.
