Abstract
A filter module for use with a room air-purifying system. The filter module includes a housing and a filter. The housing forms an air inlet, a first outlet port and a second outlet port. The outlet ports are configured for fluid connection to commercial ductwork. The filter is maintained by the housing and is configured to retain air-borne contaminants. During use, airflow passes from the filter to the outlet ports. By incorporating at least two outlet ports, the filter module preferably assumes a low-profile configuration, thereby facilitating installation of the filter module at any desired location relative to a room of interest.
