Impact of Cooking

Cooking fumes are a major cause of lung cancer. A British study has found that cooking with a bad ventilation system for one hour is equivalent to smoking two packs of cigarettes. Current range hoods are designed for the room, instead of the user. They prevent fumes from spreading, but do not protect the person cooking.

‘Ring’ is an innovative fume extractor which is designed to protect the cook’s health. Unlike previous range hoods, ‘Ring’ extracts fumes before the user can inhale them. The user will no longer need to live with the risks of cooking fume inhalation.
