Create negative pressure in the kitchen
Switch on the hood 5 minutes before you start cooking, then the vacuum is ready for efficient extraction. When the food is finished, you can appropriately reduce the power and let the hood run for 10-15 minutes, so that the air is completely cleaned.
It may be tempting to open the kitchen window, but don't. This will disrupt the air circulation around the range and prevent the range from creating the negative pressure that must suck the steam, smell and food out of the kitchen before it spreads to the rest of the home. However, there must be a supply of fresh air, e.g. through an air valve or a closed door. If you have lit the stove or fireplace at the same time, which requires air for combustion, you should leave a window open in this room.
