Motor power
The power of the hood at maximum speed.
The more powerful the device, the more performant it is, usually. However, there is no rigid dependence here, and hoods of the same power may differ in actual performance. So it is worth evaluating power consumption in terms of power first of all: the lower this indicator, the more economical the device. And when evaluating performance, you need to look not so much at power as at the directly claimed flow of the air (see below).
Flow of air (motor)
The maximum flow of air or motor flow of air indicates the theoretical capability of the device. This parameter of the hood (motor) is measured during idle operation. By connecting the duct and working in the appropriate mode of extraction, the flow of air will be lower. However, high-performance motors will also give a high flow of air in extraction mode.
Grease filter
The type of grease filter normally used in the hood. Usually, it has the appearance of a fine mesh that traps drops of fat and kitchen fumes. The grease filter can be like this:
— Metal. In this case, different materials can be used; most often, the word "metal" means a filter made of a relatively inexpensive alloy, and aluminium and stainless steel are usually listed separately (see below for more details). Common features of metal mesh are strength, durability and reusability: it is enough to wash and dry a dirty filter, after which it is ready for use again.
— Aluminium.
Filters made of aluminium alloys are considered to be very durable, because this material is highly resistant to corrosion. However, such filters are noticeably more expensive than ordinary metal ones (see above).
—
Stainless steel. Mesh made of this material has all the advantages of the metal filters described above; they are very reliable and durable, but at the same time not cheap. As a result, the use of stainless steel is typical mainly for premium hoods.
— Acrylic. A polymeric material similar to plastic. The main and the only advantage of acrylic filters is their low cost. At the same time, their service life is much shorter than that of metal ones. And some of these filters are generally disposable and cannot be cleaned after clogging. As a result, such filters are used mainly in low
...-cost models of hoods, and even then quite rarely.Height (min)
The minimum height of the entire hood structure is from the lower edge to the upper part of the body (the point of connection of the external air duct). This parameter is indicated only for hoods with an adjustable design that allows you to change the height. Pay special attention to the minimum height if the device is planned to be installed in a kitchen with a low ceiling. In this case, it should be assumed that the optimal height of the air intake above the hob is 60-80 cm, and between the hood body and the ceiling, a headroom is required for the air duct. With a low ceiling, a hood that is too large may simply not fit into your kitchen.
Height (max)
The height of the entire hood structure is from the lower edge to the upper part of the body (the point of connection of the external air duct). For hoods with an adjustable design that allows you to change the height of the case, the maximum height is the size of the device in the unfolded state; in the case of non-adjustable hoods, this means a correspondingly constant overall height. When choosing a hood in height, it is worth proceeding from two points:
1. The optimal height of the air intake above the hob is 60-80 cm. This height allows the hood to capture kitchen fumes effectively and, at the same time, gives enough space to work with the hob.
2. Between the hood body and the ceiling, a clearance is required for connecting an external air duct.
