It works but not as well as the comments said
I lived in a studio which is around 400 sqft. Cooking could make the whole room smoky. This product helps but is not that magical as the comments suggest. I have to open the window simultaneously in order to keep the smell from permeating too long. I bet it does accelerate the air ventilation and clear the dusts in some way. I still enjoy using it.
