Comparison Faber Cocktail BK A80 EV8 black vs Bauknecht DWGR 9780 black

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).

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.

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.

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.

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.

Lighting method provided as standard in the hood.

— Incandescent lamp. The simplest and most affordable of modern lighting sources. The main advantage of incandescent lamps is their low cost. In addition, they give a fairly eye-pleasing light in warm colours. On the other hand, such lamps are the most energy-intensive. Besides, they get very hot during operation.

— Halogen lamp. An improved version of the incandescent lamps described above. They are distinguished by higher brightness at lower power consumption while also having a spectrum of luminescence that is pleasing to the eye. At the same time, halogen lamps are still inferior in terms of efficiency to fluorescent and LED lamps.

— Fluorescent lamp. Also known as "fluorescent light bulbs" or "energy-saving light bulbs". One of the advantages of such lamps is just low power consumption — many times lower than that of incandescent lamps (although higher than that of LEDs). The light from fluorescent lamps is white, rather cold; this can be both an advantage and a disadvantage, depending on personal preferences and interior features. But of the unambiguous shortcomings, it is worth noting that most of these lamps contain mercury vapour in the flask; because of this, failed light bulbs must be disposed of according to special rules, and a broken lamp can become a source of health problems.

— Light-emitting diodes (LED). The most advanced of mod...ern lighting sources. LEDs are highly energy-efficient. They are more economical than incandescent lamps, and they practically do not heat up during operation. The light from such sources is neutral white, which is quite suitable for most cases. The disadvantage of LEDs is a rather high price.

Note that many modern hoods allow you to replace a regular light source — for example, a halogen lamp can be changed to a fluorescent or LED lamp with the same base.

The control method provided in the hood.

— Push-buttons. The most popular control method in modern hoods can be provided in devices of any functionality and price category — from low-cost models, where buttons directly control the motor, to high-end solutions with advanced electronic circuits.

— Rotary knobs. Control with rotary knobs, sometimes supplemented by buttons or touch sensors. A rather specific option found mainly in high-end hoods, where rotary knobs are part of the design.

— Slider. Control using the lever moved on the special panel. Usually, only power is regulated in this way: the farther the slider is from the neutral position, the more air the hood draws. A fairly universal control method, found in hoods of all price categories.

— Touch controls. Control using touch panels is considered a sign of expensive high-end hoods. It is because it makes sense to use such panels mainly with advanced control electronics and they are poorly suited for low-cost devices. From a practical point of view, the touch controls are remarkable for their ease of use and ease of cleaning: a light touch is enough to give a command, and the panel itself has no slots or protrusions, making it easy to clean dirt.

A timer that automatically turns off the hood after a predetermined time. With such a system, you do not need to wait until the completion of ventilation and turn off the device manually — just set the timer, and you can safely leave the kitchen on your own business; the hood will turn itself off at the right time.

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.
