Today the problem of how to choose a kitchen range hood interests everyone who starts a renovation in the house. Housewives pay special care to the choice of this technique. They’ve already felt what it’s like to be without a range hood. Regardless of which range hood, you decide to purchase a for the kitchen, they are all designed to clean indoor air.
WHY DO WE NEED TO CLEAN THE AIR IN THE KITCHEN?
The kitchen is a workplace for the housewife. This is done in one of two ways: by air filtration or ventilation. In the first case, the air is cleaned through special filters built into the range hood. In the second case, the polluted air is removed outside of the room. There, she spends about 60% of her time, so the condition of the air in the kitchen is directly related to her health.The air in the kitchen during preparing meals is contaminated with combustion products and the smallest food particles that are released when heated. If the room is not well ventilated, then the smells create discomfort. They affect the mood of the people and they can dishearten the appetite of even the hungriest person. Ventilation is one of the ways of dealing with polluted air. But it is best to seize the polluted air right over the stove and release it from the room. A range hood is able to handle this task. The capacity of the kitchen purifier is of great importance when you’re buying one. This parameter is determined by the amount of air that the extractor fan passes through itself per unit of time. It also depends on the efficiency of the device. According to the sanitary standards, the entire air volume must be replaced in an hour.
HOW TO CHOOSE A RANGE HOOD?
When choosing the range hood, you should pay attention to the following parameters: device type, size, capacity (performance), methods of control, modes of operation, the presence or absence of filters.
The width of range hoods cannot be less than the surface a gas or electric stove. If the size is smaller, the range hood catches polluted air worse. Even better, if the width of the range hood exceeds the width of the surface of the stove. So, if the width of your stove is 30 “, it is better for the size of the range hood to be about 35-40” That is, if you can spare the space above the stove. Ask the sales assistants about the mode your chosen range hood can work in. It could be an extractor mode, in which the contaminated air is removed outside of the apartment or the filtration mode, when the air is purified and enters back into the room, as well as the work of the fan in both modes. It is believed that 100% clean indoor air is provided by the extractor mode. But if you decide to buy an air range hood-filter, it is better to buy cartridges and change them as needed.
HOW DO YOU CHOOSE A RANGE HOOD?
When choosing a range hood one should pay attention to the following parameters: device type, size, capacity (performance), methods of control, modes of operation, the presence or absence of filters.
Which range hood control method is best for you to choose? It depends on your personal preferences. Range hood with touch controls is activated by pressing a button. Button operation involves pressing buttons. Control also can be slider-based, which means carried out using the horizontal mechanical switch.
While deciding what extractor fan to buy for the kitchen, you should pay attention to its additional functions: residual fan run, interval inclusion of the range hood. The residual stroke of the fan provides the range hood with several minutes after shutdown (from 5 to 15 minutes), which allows cleaning the air after cooking. Interval inclusion of the range hood provides for switching the device on for a short period of time (e.g., once per hour or two for 5-10 minutes at minimum power. This is done in order to keep bursting the fresh air into the room. Some range hoods have an integrated electronic timer. It should be turned on at the end of preparing a meal, so the device itself is disconnected after a certain time. Almost all range hoods are equipped with lighting devices. You can make use of incandescent lamps, halogen lamps or fluorescent lights. Of course, range hoods with incandescent bulbs are cheaper, but the devices with halogen lamps consume less electricity. It is not difficult to replace a light bulb in a range hood.
WHAT DETERMINES THE EFFICIENCY OF EXTRACTOR FANS?
The effectiveness of the device depends on many factors.
It depends on the air pressure, which is created by the motor. If the air pressure is high, then the performance will be high.
If the range hood is positioned to take the air out outside the premises, then its function will be more effective than in air recirculation mode.
An important role is played by the filters and the density of the carbon filters (if they are available). The denser the filter, the more effectively it removes the odors. But remember, that no carbon filter cleans the air for 100%. The larger the range hood, the greater is the area covered by the air entrainment. This means that there will be large eddies and sidewalls of the kitchen cabinet will not dry and shrink due to hot air that rises from the surface of a gas or electric stove.
TYPES OF RANGE HOODS.
Classic range hood.
It is a suspended range hood which is wall-mounted under the kitchen cabinet hanging over the stove. Many manufacturers offer range hoods with grease filters made of acrylic (disposable filters). Such devices operate mainly in the recirculated air mode. Disposable charcoal filters that capture small particles are required. The smell is neutralized only partially. These range hoods are considered to be the cheapest. The range hoods which, besides the addition to carbon filters, have the ability to connect to the exhaust pipe are more expensive, but they clean the air much better, and you don’t have to spend as much money on carbon filters.
Recessed range hoods.
They are mounted in a hanging locker above the kitchen stove. Usually, recessed range hoods are equipped with pull-out panels that increase the working area – the area of the air intake of the range hood. This facilitates its operation and increases the performance. The range hood is turned on in the same mode in which it is turned off. Recessed range hoods are usually equipped with two motors and multi-layered grease filters. Recessed range hoods are not much more expensive than the suspended ones, so if you guess which range hood to buy for kitchen – traditional or recessed – it is better to give preference to the latter.
Chimney (dome) hoods.
They are mounted not to the wall, but to the ceiling above the surface of a gas or electric stove. They are called chimney hoods because of their domed shape, which resembles a chimney. These hoods exist in three types: metal with glass, metal, classical drawing wood or decorated with natural wood. The design of the dome hoods is versatile and their form can be very interesting.
FUNCTIONAL FEATURES OF THE DEVICE.
Modern range hoods are able to remove up to 96% of odors and air pollution that remain after cooking meals. Especially necessary are the range hoods which are combined with the living room. In such cases, it is important that the range hood not only has high performance but also works quietly enough. The operation of the device can be evaluated as “very quiet” if the noise created by the motor and the air flow is comparable to a whisper (up to 35 decibels). If the noise can be compared to a conversation at a distance of 15 Ft (45 decibels), then the range hood can be called quiet. If your kitchen is isolated (not combined with a room or dining room), you may not experience the inconvenience associated with the range hood, whose noise level is about 50 decibels (comparable to a quiet conversation at a distance of 10Ft). This level of noise is estimated as “normal”. It is not recommended to purchase a range hood if the noise level exceeds 50 decibels. For example, the noise of 70 decibels is impossible to ignore: it is comparable with a loud conversation at a distance of about 15Ft. When choosing a range hood, don’t forget to take into consideration the case material. It can be plastic, enameled steel, stainless steel, tempered glass, aluminum. Machined aluminum has the most attractive quality/price ratio. The matte surface of this material goes well with many types of kitchen equipment. The aluminum case does not show fingerprints. It does not corrode and is very easy to clean. Stainless steel housing combined with tempered glass looks very stylish. There are also very expensive models, which are made by custom configurations taking the wishes of the client into account.
