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.

Flow of air (extraction)

The performance of the hood in extraction mode at maximum speed shows the real possibilities for air purification. Since this parameter is several times less than the motor performance (maximum performance), not all manufacturers indicate this value, trying to present large and beautiful numbers. A similar situation can be observed among other devices. For example, in vacuum cleaners, the total power is many times greater than the suction power; in acoustics, mediocre brands prefer to list peak power instead of nominal power. Therefore, motor performance and extraction performance can not be compared. However, high-performance motors will also give high performance in extraction mode. And it may well be that the conditional Bosch with an extraction performance of 300 m³/h will be better than another hood with a maximum motor performance of 500 m³/h.

Minimum noise level

The volume at which the device operates in the quietest mode. Usually (but not necessarily) it is the minimum power mode.

The decibels in which the noise level is measured are non-linear units, so it is easiest to use comparison tables to estimate a specific value. Here is the simplest table for minimum noise in modern hoods:

— 20 dB. Almost inaudible. The volume of a whisper at a distance of 1 m, the sound background in an open field on a calm day.
— 30 dB. The whisper, the ticking of the clock. The maximum noise level allowed for residential premises at night.
— 40 dB. The volume of normal human speech. The maximum permissible sound background (permanent) for living quarters during the day.
— 50 dB. Conversation of several people in medium tones.
— 60 dB. Loud talk.
— 65 – 68 dB — background noise on a city street, a vacuum cleaner engine at a distance of 2 – 3 m. The highest noise level among modern hoods is typical for powerful performant models.

When choosing according to this indicator, note that, other things being equal, a quieter device will, accordingly, cost more.

Max. noise level

The level of noise produced by the hood in the loudest mode of operation. Usually (but not necessarily) it is the maximum power mode. It affects the comfort during operation of the device, so quiet hoods will be more preferable, but also more expensive.

The decibels in which the noise level is measured are non-linear units, so it is easiest to use comparison tables to estimate a specific value. Here is the simplest table for the values relevant in this case:

— 35 dB. The volume of a conversation in an undertone (but not a whisper). The lowest maximum noise value in modern hoods. Devices with such characteristics are almost guaranteed not to cause inconvenience: such noise is often blocked by other sounds, for example, the background noise of the street in an open window.
— 40 dB. The volume of a normal conversation. The maximum noise level allowed in a residential area during the day. If the hood is bought for home use, and it is supposed to be turned on often and for a long time, the noise level in the selected device shouldn't exceed this indicator.
— 50 dB. Conversation volume at medium tones.
— 60 dB. Raised conversation.
— 70 dB. Sound background on a busy street, in a crowd of people talking loudly, the sound of a vacuum cleaner motor at a distance of 2 – 3 m.
— 75 dB. Scream or loud laughter at a distance of about a metre.
— 78 – 79 dB. Loud mechanical alarm clock, motorcycle o...r truck engine. The highest level in modern consumer-grade hoods.

Note that the actual comfort of using the device depends not only on the volume but also on the timbre (tonality) of the noise: for example, a low, even rumble is generally perceived easier than high frequencies with clanging notes. If the hood installation is unsuccessful, the actual noise level may be higher than stated in the specifications. For example, additional noise can be caused by the hum of air in the ducts or rattling from the contact of the vibrating body with the wall. However, when choosing, it is worth focusing on the noise level claimed in the specifications.

Carbon filter model

The model of the carbon filter compatible with the hood. For more information about such a filter, see "Ability to install carbon filter". Here we note that the carbon filter is not always supplied in a kit, and its service life is limited, periodic replacement is required. Anyway, the data on the filter model makes it much easier to find.

Energy class

This indicator characterizes how economically the hood consumes electricity. Initially, classes were marked in Latin letters from A (highest) and further down as they went down; later, improved classes A+ and A++ appeared. (the more pluses, the better). More energy-efficient models are more expensive but can pay for themselves in the process of use, especially if you have to cook often and in large quantities.

Duct diameter

The duct diameter characterizes the size of the hood outlet to which the ducts are connected. The standard is either 120 mm or 150 mm. In many cases, an adapter from one diameter to another can additionally be included with the device. However, when replacing the hood with a new one, it is still better to operate with the existing pipe diameter and not use adapters.

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.
