Evaluation of culturable particle load on HVAC filters before and after remediation : a pilot study

The evaluation of a quantitative method for culturing particles on HVAC filters is the aim of this research. Two phases for that study : first, a case study comparison of two HVAC filters from a building with a history of IAQ concerns and secondly remediation efforts in the same building. This limited study has been carried out for prelimimary assessment of the use of a filter quantification method to evaluate relative airborne fungal load.
