Comparison Minola HTL 5614 WH 1000 LED white vs Minola HTL 5714 WH 1100 LED white

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, 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.

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.

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.

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.
