The word Air Freshener is a substance used in controlling odor and wide unpleasant smells especially those in the environment. It is related to the Latin word perfumery (to fill with smoke), (Golden, 2003). Air fresheners are pervasive within indoor built environments, such as workplaces, schools, housing, transportation, hotels, hospitals, care facilities, and a range of private and public buildings. Air fresheners are designed to impart an aroma to the air environment or to mask odors, with the intent of creating a pleasing indoor space. Also to provide an alternative source of raw materials for the production of Air fresheners. Air fresheners also include so-called air care, deodorizer, odor control and neutralizer products. In addition to site-specific units or portable products, air fresheners can include scented air systems, which deliver fragrance throughout a space, such as by connecting a fragrance diffuser to the heating, ventilation, and air conditioning system. In conclusion, air fresheners are used throughout society, often with the intent to create a favorable indoor air environment. However, air fresheners may come with unintended and perhaps invisible risks.
