Mean recovery rates in % of the aerosolized surrogates at different RH.

N represents the number of measurements per humidity range. Three air samples were simultaneously analyzed per measurement.</p

Predicted concentration of S. aureus (a), spores of G. stearothermophilus (b) and MS2 bacteriophage (c) per m3 at different RH (black line). The symbols represent the raw measurements in cfu or pfu per m3 in different impinger heights. The shaded areas indicate the upper and lower 95% confidence interval.</p
