01
Extraction power
This criterion measures the maximum air flow the hood can extract, expressed in cubic metres per hour. The higher this flow, the faster the hood clears smoke, steam and cooking odours, which matters most in an open kitchen or with intensive cooking. On the site, the score places each hood against market readings: the weakest models plateau around two hundred and twenty four cubic metres per hour, the median sits near five hundred and twenty seven and a half, and the best approach seven hundred and twenty five cubic metres per hour. A high score here guarantees effective extraction even during heavy cooking.
Market median: 527.5 m³/h
02
Noise level
This criterion measures the noise produced by the hood at full power, in decibels. Here, lower is better: a quiet hood goes unnoticed even at maximum speed, while a loud one tempts you to lower extraction for comfort, at the cost of efficiency. Market readings show wide gaps: the noisiest models reach seventy decibels, the median sits at sixty four and a half, and the quietest drop to fifty five decibels. A high score on this criterion signals a discreet appliance, not just a powerful one.
Market median: 64.5 dB
03
Number of speeds
This criterion counts the extraction speeds available on the hood. The more there are, the easier it becomes to match extraction to each type of cooking, from simple simmering to frying that releases a lot of steam. On the market, the simplest models offer three speeds, which also matches the median, while the best equipped offer five. A higher number of speeds allows finer control, useful for saving energy and limiting noise during light cooking.
Market median: 3
04
Annual energy consumption
This criterion measures the energy the hood consumes over a year of use, in kilowatt hours. A lower value is preferable: it points to an appliance that weighs less on the electricity bill, especially with daily use. Market readings place the most demanding models around seventy four point three kilowatt hours, the median at fifty point four, and the most frugal around thirty eight point seven kilowatt hours. Comparing this criterion helps anticipate the real cost of ownership, beyond the purchase price alone.
Market median: 50.4 kWh
05
Lighting over the cooking zone
This criterion counts the number of bulbs that light the cooking zone. The more there are, the better dishes are lit during preparation, a welcome comfort for watching delicate cooking closely. On the market, the least equipped models offer only one bulb, the median sits at two, and the best equipped offer four. This criterion weighs less than power or noise in the final choice, but it is worth comparing if the kitchen already lacks natural light.
Market median: 2 bulb(s)
06
Installation and upkeep
Beyond the measured criteria, fitting a hood depends on the kitchen layout: ducting to the outside or recirculation through a carbon filter, ceiling height, and the distance required above the hob. Regular upkeep of the grease filters also shapes performance over time, since a clogged filter reduces real extraction, even on a well rated model. It is worth checking how easily the filters come out and clean before buying, since this daily task affects comfort far more over the long run than a figure shown once on the sheet.
