Indoor air quality is an international concern, linked with adverse effects on health and productivity. A common source of indoor air pollutants is fragranced consumer products, such as air fresheners, cleaning supplies, and personal care products. Exposure to fragranced products has been associated with health problems, such as breathing difficulties and migraine headaches, as well as lost workdays and loss of access in society. In response, fragrance-free policies have been implemented in workplaces, schools, health care facilities, public buildings, and other indoor environments around the world. In addition, national surveys indicate that more people prefer fragrance-free rather than fragranced environments, and would support fragrance-free policies. Though lacking a standard approach, these policies generally restrict the use of fragranced products indoors. And though prevalent, little systematic study has investigated these policies. Yet building managers, occupants, employers, and employees often seek guidance and scientific information. This paper presents and answers ten questions to explore fragrance-free policies within indoor built environments. Using a set of 60 fragrance-free policies, it analyzes who, what, where, when, why, and how policies are implemented. It then examines potential benefits of fragrance-free policies, such as avoided costs from illness and lost workdays, as well as challenges. The paper concludes with guidance and research directions for the future
