Abstract

This work tested performance of four commercially available plain filters with single-path particle removal efficiencies of 25%, 65%, 85% and 95%, respectively. Each grade of filter was installed in the return air vents of fan-coil units of a classroom and multi-day continuous monitoring of indoor and outdoor particulate matter with diameters of 10 nm to 10 μm was carried out during both occupied periods and unoccupied periods. In addition, air exchange rates, fan energy consumptions and noise levels before and after the filter installation were measured in each classroom. Here we reported some preliminary findings on the air exchange rates, filter particle loading and background noise levels in the classrooms.
