Comparison Elica Elite 14 PLUS IX/A/60 stainless steel vs Elica Elite 14 LUX GRIX/A/60 stainless steel

Modes supported by the hood.

— Extraction only. The device draws in the air in the room and takes it to the ventilation shaft or directly to the street. It is a very effective way to clean the air from pollution: all impurities, including odours, are simply removed. However, when the hood is operated in this mode, you must either open windows or provide adequate ventilation. Because of this, this mode is not always appropriate: for example, in the cold season, not only pollution but also heat can fly out into the chimney. Therefore, in most modern hoods, a recirculation mode is also provided.

— Recirculation. An operating mode in which the hood does not draw air from the room but drives it through its own filters. This mode is not as effective in terms of air purification as extraction. To effectively remove odours you need to use absorbent filters, that have a limited service life. On the other hand, recirculation does not require an intensive flow of outside air, which in some situations is important — for example, in the cold season, when it is undesirable to blow out the heated air from the room.

The vast majority of modern hoods support both modes of operation. Occasionally, some models are not compatible with carbon filters and work only in extraction mode; even rarer — devices with recirculation only mode.

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 ability to install an additional carbon filter in the hood — in addition to the grease filter (see above).

It provides finer air purification than a grease mesh: the carbon filter is capable of retaining impurities literally at the molecular level. Due to this, it is possible to effectively clean the air from not only kitchen fumes but also odours that are not associated with smoke, steam and other relatively large impurities. However, the carbon filter has a limited service life, and it has to be changed from time to time (cleaning, in this case, is not an option).

Note that, in this case, we are talking only about the compatibility of the hood with a carbon filter. The filter itself may not be supplied. However, in many models with this function, it is available as an option (included or not included in the kit at the request of the user).

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.
