A clean room ventilation system having a diffuser panel attached to a ceiling grid, with a filter element positioned well above the panel. The diffuser panel is perforated throughout its area with increased size and/or density of perforations in a peripheral region to provide increased airflow beneath the ceiling grid. The peripheral regions may further be angled to create a lateral airflow beneath the ceiling grid.
