An Airbnb was having complaints from guests that odors from previous guests remained in the unit, making it unpleasant. A WZ-300 Whiffer Zapper was placed on the refrigerator in the Airbnb unit. It removed the odors and diffused a pleasant scent. The unit has operated effectively for 5 years. There have been no complaints about residual odors inside the Airbnb unit. One guest said the fan running in the Whiffer Zapper was a distraction.
