Range Hood

Range hoods AKA cooktop hoods are essential equipment for kitchens, laboratories, covered parking lots, etc. The following provides information, specifications, models, brands, important factors, and the best price for all range/kitchen hoods.

Range Hood Review, Selection, and Price

Range hoods, which are usually installed above the gas stove, are considered a key accessory in domestic and industrial kitchens, in addition to being a type of ventilation and deodorization device, they significantly affect the beauty of the place.

In general, cooktop hoods are in charge of removing the smell, smoke, and steam that is created during cooking. In other words, the range hood drives out the smell of food, smoke, moisture, and fat suspended in the air, improving the air quality and keeping the humidity level of the house constant.

Also, the proper functioning range hoods and vents will prevent cooking grease and moisture accumulation on the ceiling and walls of the kitchen. If a cooktop hood is not used in the kitchen, the rise of humidity and fat in the air provides the conditions for the growth of fungi and molds and endangers the health of family members.

How to Calculate the Ventilation Power of the Cooktop Hood

If you want to choose an efficient range hood for your kitchen, after calculating the dimensions and volume of your kitchen space (length x width x height), choose a hood that can exhaust kitchen air 15 times per hour (according to engineering standards).

For example, if the dimensions of your kitchen are 2.8 x 4 x 3 meters, its volume is equivalent to 34 cubic meters, and therefore the power of the cooktop hood to exhaust the air in the desired kitchen will be equal to 510 = 15 x 34 cubic meters per hour.

Note: If, for any reason, it is not possible to vent the required amount of air out of the kitchen, the smell of food and smoke will remain in the kitchen.

Extra: The cooktop hood fan's power to vent the volume of air, also depends on the static pressure power of the range hood fan and the diameter of the air vent channel.

Factors to Consider When Choosing a Cooktop Hood

There are a few points and factors you need to be aware of to buy a more efficient range hood, which are as follows:

• Considering the weak suction capacity as well as the static air pressure power of many range hoods in the market, before buying your cooktop hood, you must check on the necessary information such as the air suction capacity, static pressure (the ability of range hood to pass air through the kitchen chimney), engine power, diameter and the height of the air suction fan of the mentioned cooktop hood, otherwise your range hood will only be an inefficient device that is not able to expel smoke, odor, and steam, and will only disturb you and your family members by making noise.
  
  
  
• To increase the efficiency of the cooktop hood, try to choose the length and width of the kitchen hood and the gas stove close to each other.
  
  
  
• The sound level of the cooktop hood is usually the sound produced at the average speed of the range hood motor, and it may be louder at higher speeds, if the declared number is in the range of 53 to 63 decibels, it is considered a normal sound for the cooktop hood.
  
  
  
• Some range hood models have sensors sensitive to odors and smoke so that the cooktop hood automatically turns on and ventilates in the presence of odors and smoke. Of course, sometimes these sensors may become too sensitive and turn on unnecessarily, which is nothing to worry about.
  
  
  
• Another important point is matching the outlet of the cooktop hood with the outlet of the air vent. If the outlet of the air vent does not match the outlet of the range hood, the empty space created will cause additional noise in the range hood, and the exhaust of polluted air may not be done completely.
  
  
• The motor of the new range hoods is of the turbine or spiral type, these motors, in addition to being stronger than normal motors, also produce less noise.
  
  
  
• The filter of the new range hoods (flat range hood, diagonal range hood, built-in range hood, island range hood) is made of aluminum and can be washed by hand and dishwasher (2-hour program), but the filter of the old cooktop hoods (under cabinet range hood) is made of glass wool, which cannot be washed and must be replaced.
  
  

Types of Range Hoods

In household range hoods, all the equipment, including the air suction fan, motor, etc., are placed in the corresponding box, and only the polluted air is pushed out of the house through the air vent.

In industrial range hoods, generally, a powerful centrifugal suction fan is placed outside the exhaust hood and on the roof of the building, and it transports the polluted air through the opening of the range hood and then the duct.

Household range hoods have different types and designs, which are fully described below:

Under cabinet Range Hood

The under cabinet range hood, which has a very simple design, is considered one of the old models of the range hood, its motor has an air suction fan and its filter is made of glass wool fibers.

These types of cooktop hoods often produce a lot of noise compared to kitchen hoods Nowadays, it has fewer features and beauty and its filter cannot be washed. Reasonable prices and low maintenance costs are the advantages of under-cabinet range hoods.

Flat Range hood

Flat range hoods are installed on the wall and are usually equipped with a washable aluminum filter and a system for detecting the time of washing and changing the filter. The suction plate of the flat cooktop hood is completely placed above the gas stove face, therefore it has the best suction among all types of household range hoods.

The lighting of the range hood is provided by halogen or LED lamps. Some models of flat kitchen hoods have an automatic shut-off timer and a sensor sensitive to smell and smoke. In some flat range hood models, glass is used as a body part.

Wall decorative Range hood (Diagonal)

Diagonal range hoods that are installed on the wall are placed at an angle of 45 degrees to the gas plate. wall range hoods, if they don't have a powerful motor, may perform poorly in sucking polluted air compared to other cooktop hoods, but still, many people choose diagonal cooktop hoods among all types of range hoods because of their beautiful and different design.

However, in diagonal range hoods, a powerful motor and suction fan turn the page so that there is no difference between a diagonal and flat kitchen range hood in terms of air suction. And the sound level, like other kitchen hoods, varies depending on the motor.

Diagonal range hoods are produced in glass, steel, and stainless steel designs, these cooktop hoods are equipped with a washable aluminum filter and a system for detecting the time of washing and changing the filter.

Depending on the model, it is possible to control the parts of the cooktop hood through a remote control, touch screen, or mechanical button. The lighting of the range hood is through a halogen or LED lamp. Some models have an automatic shutdown timer and a sensor sensitive to smell and smoke.

Built-in Range Hood

The hidden or built-in range hood is placed completely under the cabinet and in fact, there is no view of the range hood in the kitchen. The advantage of this range hood is that it does not take up space for the cooktop hood in the kitchen. In terms of suction sound and other features, the built-in range hood is no different from the flat range hood and diagonal vent hood.

Island Range Hood

The range hoods of the island design are very beautiful and fancy in terms of appearance and are designed in cube, cylindrical, and sometimes spherical shapes and have the characteristics of a flat range hood, but due to the small suction plate they have, they are more suitable for kitchens in terms of efficiency if first of all, the size of the gas stove is small, and secondly, less cooking is done in them.

They are mostly considered decorative and luxurious. The new and beautiful model of the island range hood is the elevator cooktop hood model, which can be raised and lowered and can be folded and opened by touching its button.

Range Hood Buying  Tips

·         To install the cooktop hood, be sure to contact the representative of the purchased brand and try not to exceed the distance between the gas stove and the range hood more than 60 and 80 cm (standard mode).

·         When you turn on your gas stove, be sure to turn on the cooktop hood as well otherwise the heat produced from the gas stove will damage the range hood filters and you may have to replace the filters.

·         The range hood pulls the pollution in the air towards itself, that's why inside the cooktop hood is a suitable space for the growth of molds and bacteria. Try to clean all filters at least once a month, especially if you use a grill. You can easily wash the metallic filters in the dishwasher (of course, on the suitable washing program). You can also use special detergents to clean range hoods made of non-oxidizing metals.

• To clean glass range hoods, do this at least 1 hour after turning off the hood.
• To clean stainless steel range hoods, use special steel protector cleaners.
