TEST BATCH CONDITIONS
Virus capture testing was carried out using an
aqueous aerosol challenge of MS-2 coliphage
(23nm) at 109pfu, 30l/min and R.H. >95% for 1
minute. Virus retention was carried out after virus
capture. A clean air flow of 30l/min was passed
through the sample. Virus removed from the sample
was calculated as a percentage of the virus retained
within the sample.

for potentially low-oxygen spaces should be followed.
