What is an extraction rate?

Cooker hoods come with different extraction rates, which determine how quickly the air is changed in the kitchen. It’s recommended that your cooker hood should change the air around 10 times per hour. So, the larger the kitchen the higher the extraction rate.

The extraction rate your kitchen needs all depends on its size. The faster the extraction rate the faster the air will be cleaned, although the noise level may go up, so faster isn’t always better. Take a look at how to work out your extraction rate above.
