When we cook food, it produces smoke, steam, and sometimes bad smells. Kitchen ventilation is like an escape route for these things to leave and not make us uncomfortable while cooking or eating. It's like the kitchen's breathing system.
When we turn on the kitchen ventilation, it helps to take away the smoke, steam, and odor produced while cooking. This ventilation may be in the form of an exhaust hood, an exhaust fan or even a window that can be opened.
The exhaust hood is installed over the cooking surface/stove, and it is like a big vacuum cleaner that sucks away the smoke created. And its filter saves grease from building up in the kitchen. On the other hand, the exhaust fan helps take the air from around the cooking area and pushes it outside.
We need to ensure that we use the kitchen ventilation when cooking to maintain a healthy environment in the kitchen. If we don't, then the smoke and other irritants could stay in the air, making it hard for us to breathe properly.
In summary, kitchen ventilation is like the kitchen's breathing system that we need to use when cooking. We need to use it so that the smoke, steam, and smell from the food we're cooking can escape and make the air we breathe easier to bear.
