Not efficient at smoke odor removal

Very disappointed in this units ability to clear smoke odor from a room. We ran this in a room downstairs where 2 cigarettes were smoked. The smoke odor still filtered throughout the entire house; even with the "ionizer" feature turned on. On the plus side, the unit is easy to operate and fairly quiet on the two lower fan speeds. It gets a bit noisy on the highest level; which is what we ran it on to try and contain the smoke odor.
