I've had that for two apartments in a row. The most it can do is direct fumes to the ceiling instead of in your face. Incredibly little effect, when I then need to had the windows open with a box fan for a few hours any time I pan-fry anything. It's very frustrating, as those fumes could have been caught and exhausted from the source with much less exchange of air.
