Abstract

Home air purifiers (HAPs), utilizing HEPA filtration as the primary mechanism of air cleaning aim to reduce particulate matter (PM) concentrations that are known to be harmful to health. In the work described here, PM2.5 concentrations were continuously monitored for 6 months inside and at the ground floor exterior of 18 flats in London. Median bedroom PM2.5 concentration of all flats was measured at 14 µg m-3 in the bedroom at the start of HAP operation. In the bedrooms where the HAP was in use, a clear decay curve was seen resulting in a 45% reduction of PM2.5 over 90 minutes of run time. Based upon these findings, and the published positive association between PM2.5 and asthma (OR = 1.28 per 3.2µg/m3 ), an estimated 1,361 additional QALYs per 10,000 children were achieved using HAPs in health impact models.
