Abstract
BackgroundAir pollution is of significant environmental and public health concern globally. While much research has historically focused on outdoor air pollution, indoor air pollution has been relatively under-explored despite its strong connection with health outcomes, particularly respiratory health. Studies on air pollution exposure mitigation consistently reveal a significant knowledge gap between the understanding of air pollution as a health risk among lay individuals and expert scientists. This study aimed to assess how people define and understand the concept of ‘clean air’ within their home setting.MethodsWe adopted a mixed-methods approach which used a guided questionnaire designed to elicit both quantitative and qualitative data, collected as digital voice notes. The total sample (n = 40) comprised data from two socially different sites of science and non-science events. We compared whether the notion of clean air inside homes differs between these two different social contexts and how views and ‘sense’ of indoor air pollution are formed. The concept of ‘place’ facilitated fluidity in our explorative analysis. Insights allowed us to assess the extent to which context mediates individuals’ perceptions of indoor air pollution and attitudes towards health risk.ResultsWe found that individuals’ insights were embodied in repetitive day-to-day activities (e.g. cleaning and cooking). Three key themes emerged (1) Stimulative Effects, (2) Contextual Conditions, and (3) Risk Attitudes. Sensory perceptions such as sight, smell and temperature primarily motivated participants to assess air quality inside their homes. These perceptions were shaped by contextual conditions, influencing how individuals perceived their health risk and were subsequently motivated to spend personal time considering or seeking information about household air pollution, or improving their home air quality.ConclusionsOur insights revealed that social, geographical, and contextual factors play a crucial role in individuals’ understandings of indoor air pollution. These dimensions should be integrated into designs of effective public health risk communication strategies. Our findings highlight that common lay perceptions and practices intended to improve air quality may pose health risks. Therefore, risk communication about household air pollution must extend beyond objective information by considering contextual factors that shape how people interpret and respond to air quality issues.Clinical trial numberNot applicable.
