How much extraction power does the hood need?

The performance of a kitchen hood is the ability to “suck” air for an hour. It is this indicator that determines the efficiency of.

Sanitary regulations state that kitchen air needs to be refreshed 10 times per 60 minutes.

In order to choose the most suitable device for your apartment and not to listen to the sellers, whose task, let’s not lie, to sell you a more expensive hood, before you go to the store, make a simple mathematical action:

S of the kitchen length × width × ceiling height × 10 = the minimum hood capacity you need.

But there are certain nuances to consider:

1. That’s the minimum capacity the hood needs for 1 speed.
2. The manufacturers calculate this value when the unit is in extraction mode and it is set as follows: 1 m duct + 90° elbow + 1 m duct. If you are planning a more complex installation: several bends, longer ductwork, the hood will not work with the performance. Add 20% for every bend.
3. If you plan to use the hood in recirculation mode the air cleaned by the charcoal filter is returned to the kitchen , then add 30%.
4. Reputable manufacturers, well-known brands, use this methodology to calculate the performance of their hoods. How little-known one-day companies count – it is not known, but they often do not indicate the minimum hood, indicating only the maximum rate. That’s why you should choose the manufacturer carefully.

Choose your cooker hood before you go out and then you’ll be pleased with how it performs.
