Let’s be honest, when it comes to small studios or one-bedroom apartments having a well-ventilated kitchen is very important. When cooking anything at all there are always going to be smells, no matter how well you try to control them.
Cooking smells linger around a house because of their molecular structure. You see, molecules are very sticky; they stick to surfaces and tend to stay where they land. Since certain molecules remain in the air it makes it very easy for them to attach themselves to fabrics, like carpets and drapes, as well as other surfaces like cabinets and tables.
Because of this, it makes the smells impossible to completely get rid of, so there is always going to be a slight scent around your house.
