Task: Wrong Candidate Generation
Input (English): How to remove smells from a musty basement or other lingering odors.
Output (English): If simply opening the doors and windows doesn't remove the smells, you know their source is embedded more deeply. A treatment of ozone throughout the area will decontaminate and deodorize the area including rugs and walls in a few hours. Make sure there is no one in the house, and clear out the ozone before allowing people back in, by closing the doors and windows afterward.
