This filter is used in a room where cigarette smoking is a constant. The old filter was covered in a greenish-yellow residue,evidence that the smoke and nicotine were effectively being captured. Not on the walls and window. Air quality is high , with little noticeable detection of cigarette odor.

I have the T300 with odor filter in my living room and it works very well! It clears cigarette smoke odors from the air (condo hallway air comes into foyer). No complaints; easy to use and highly recommended.
