How do you know that a kitchen ventilator is efficient?

Fume extraction capability The fume extraction capability of a kitchen ventilator is the characteristic which ultimately determines whether the ventilator is efficient. The expression itself is a little difficult and not that easy to remember. Other popular expression that are used in an attempt to describe the same characteristic include "extraction capability", "suction effect" or, quite simply, "how well the ventilator sucks".

The crux of the matter is that there is a difference.A high fume extraction capability and "good suction" are not the same thing. And how well the kitchen ventilator sucks, or how much air it sucks out, is not synonymous with how efficient it is. The fume extraction capability, on the other hand, indicates the proportion of the cooking odours that the ventilator is able to collect, separate and discharge.

Fume extraction capability is measured with the help of tracer gas tests. The result is stated as a percentage value. The Swedish Consumer Agency (Konsumentverket;KV) measures this in its regular ventilator tests. The average value in the most recent of these tests was 91.9 %.The best result was achieved by our creation, the Futurum Supernova, with a score of 95.1 %. This is the highest value ever recorded in the KV's tests.

Perhaps the difference between 95.1 %and 91.9 %does not seem very large. It is larger than you imagine, however. Especially if you go on to compare the amount of cooking odours left behind by the kitchen ventilators. The Supernova's 4.9 %(100 minus 95.1) against the average ventilator's 8.1 %. The average ventilator thus leaves behind almost twice the amount of cooking odours!

A good piece of advice to anyone intending to purchase a kitchen ventilator and who wants to have a true indicator of the efficiency is thus: ask your dealer about the test results for the fume extraction capability.

What is myth and what is true?
