Comparison ELEYUS Vesta A 750 LED SMD 60 S BL black vs ELEYUS Vesta A 1000 LED SMD 60 BL 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 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, motorcycl...e or 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.

The number of speeds at which the hood can operate.

The more speeds, the more accurately you can adjust the device's operating mode to a specific situation. At the same time, the vast majority of modern hoods have only three speeds which are enough for most occasions.

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 remote control allows you to control the functions of the hood from a distance. Such a remote control will be especially convenient for those who, due to low height or health problems, find it difficult to reach for the hood itself every time. At the same time, this function affects the cost of the device, and the need for it arises relatively rarely. Therefore, the presence of a remote control is typical mainly for rather expensive models.

The hood has its own display. Usually, this is the simplest LCD screen for two or three characters, sometimes with additional indicators. However, even such a screen makes device control more convenient and visual: it can display the current operating mode, information about the sleep timer (see Sleep timer), the status of filters (see Filter indicator), etc.

This function rarely is used in inexpensive hoods with the simplest functionality. Therefore, the display is usually a sign of an expensive and advanced model.

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.
