a Chamber experiments comparing the wet cyclone performance with the BioSampler® and LSS for three aerosolized virus concentration levels: <500 copies/m3 (low; n = 3), 500–10,000 copies/m3 (medium; n = 2), and >10,000 copies/m3 (high; n = 4). The data are presented as mean ± 1 SD of ‘n’ independent experiments (b) typical concentration of SARS-CoV-2 RNA copies measured in indoor air; the vertical dotted lines demarcate the low, medium and high virus concentration test levels; c PCR Ct value (inverted y-axis) of indoor air samples collected using the wet cyclone in apartments with SARS-CoV-2-positive patients (n = 7) and control room (n = 3). The data are presented as mean ± 1 SD of ‘n’ independent samples.
