It really works!!
I was skeptical at first, but I live in NYC. Our rooms are generally small and cramped. I hooked this up in a smaller bedroom that had been smelling dingy. After several hours, I returned to the room and there was a noticeable difference in air quality. I also hooked it up in my kitchen. The fumes and hanging aura of smoke greatly decreased after a few hours. Its a necessity especially in the winter months in small cramped apartments where windows can't be opened because of the cold.
