Finding F-0115

“Under the outdoor PM2.5 concentrations of <35 μg/m3, the averaged CADRActual of house A and house B were 7.8 ± 0.3 and 9.7 ± 0.4 m3/min, respectively.”

Structure

Factor: Particulate matter (PM₂.₅ and PM₁₀)
Intervention: Air purifiers
Setting: home, KR
Study design: field measurement study: actual clean air delivery rate of one air purifier derived from particle decay rates with and without the purifier over a month in two residential houses of different airtightness (ACH50 4.8 h−1 and 2.1 h−1), at different outdoor PM2.5 concentrations (class 4)
Effect: other 7.8
Sample: 2 homes
Caveat: printed as ± 0.3 without naming the measure of spread
