An elderly couple owns a small condominium. His health deteriorated to the extent that he could no longer get out of bed. His wife did her best to keep his bedding and clothing clean, but residual odors were obvious to any guests who entered their home. A Whiffer Zapper in the bedroom and living room made all the difference. It removed residual odors and diffused a pleasing scent that can be smelled throughout the home. Now guests are not offended by odors as they visit the home.
