Portable air purifiers (PAPs) have been shown to reduce indoor PM2.5 concentrations significantly, potentially offering health benefits. However, evidence on health impacts is limited and inconsistent.
A systematic literature review was carried out to examine the impact of portable air purifiers (PAPs) on indoor air quality (PM2.5) and health, focussing on adults and children in indoor environments (homes, schools and offices). Analysed studies all showed reductions in PM2.5 of between 22.6 and 92.0% with the use of PAPs when compared to the control. Associations with health impacts found included those on blood pressure, respiratory parameters and pregnancy outcomes. Changes in clinical biochemical markers were also identified. However, evidence for such associations was limited and inconsistent. Health benefits from a reduction in PM2.5 would be expected as the cumulative body of scientific evidence from various cohort studies shows positive impacts of long-term reduction in PM2.5 concentrations. The current evidence demonstrates that using a PAP results in short-term reductions in PM2.5 in the indoor environment, which has the potential to offer health benefits.
