Research: Impact of High-Efficiency Filtration Combined with High Ventilation Rates on Particulate Concentrations in U.S. Offices

“The NAFA Foundation’s recent funding of the research project (co-sponsored by ASHRAE), conducted by Associate Professor Michael Waring of Drexel University, provided NAFA members with valuable information relative to the impact of high-efficiency filtration, when combined with high ventilation rates, on particulate matter concentrations in U.S. office space. The estimated public health gains associated with using high efficiency filters in office buildings far exceeds the additional cost of the more expensive high efficiency filters. The study also concluded that the efficiency of the filter has no observable effect on fan energy consumption."
