Description:
The Environmental Technology Verification report discusses the technology and performance of the AFP30 air filter for dust and bioaerosol filtration manufactured by Airflow Products. The pressure drop across the filter was 62 Pa clean and 247 Pa dust loaded. The filtration efficiency when the filter was clean was 25% for Bacillus atrophaeus, 45% for Serratia marcescens, and 40% for bacteriophage MS2. The filtration efficiency when the filter was dust loaded was 83% for Bacillus atrophaeus, 88% for Serratia marcescens, and 91% for bacteriophage MS2. The ASHRAE 52.2 dust filtration efficiency was 7% for particles between 0.3 and 1.0 micrometers, 40% for particles between 1.0 and 3.0 micrometers, and 58% for particles between 3.0 and 10 micrometers. The minimum efficiency reporting value was 7 at 0.93 cubic meters per sec.
