Noisy fan
Bought this for our mud room to help eliminate the smoke odor left by the previous owner of our home who smoked in the garage (we coated the inside of the garage walls with two coats of Killz to mitigate the odor in there and it worked).  While it did help to reduce the faint smell when you fist walked into the house from the garage, it did not eliminate it completely. And the noise the fan made while it was running could be heard in the adjoining kitchen and dining area, which we we found annoying.  We returned this item for those reasons.
