• Description:
  The National Institute for Occupational Safety and Health (NIOSH) has undertaken a long-term performance test of heating, ventilation, and air-conditioning (HVAC) system filters. This testing is being conducted at the NIOSH facility in Morgantown, WV in an air handling unit (AHU) that services the animal quarters. The filtration needs of animal quarters are similar to that of a medical facility due to presence of immune compromised animals. The medium efficiency bag filters in this AHU have been replaced with higher efficiency mini-pleat V-Bank filters and have been monitored monthly for filtration efficiency since they were installed. This study required the development of a method to determine the actual HVAC filtration efficiency using optical particle counters while the system was in operation. Grimm aerosol monitors with isokinetic sampling inlets were used to collect particle counts in 15 different particle size ranges from 0.30 um to 20 um. The challenge aerosol was the ambient particulate within the HVAC system. [Description provided by NIOSH]
