An environmental control system providing a healthful environment in an enclosed structure for people living, working, travelling, or spending leisure time in the structure. The environmental control system may include a heating, ventilating and air conditioning unit, for controlling the temperature and humidity of air within the structure and pressurizing the interior of the structure, and an air cleaning system. The air cleaning system preferably includes a pre-filter unit to remove larger particulates, a medium efficient extended surface type filter device for capturing smaller particulates, a chemical and/or activated carbon filter device to provide gas phase air purification and scrubbing, and a high efficient particulate air filter device. If desired, an electronic air filter device can be included. An air quality measuring unit monitors the cleanliness of the air passing from the system. Pressure measuring devices may be installed across each filter unit so that the need to clean or replace a particular filter unit can be determined from a higher than normal pressure drop across the unit.
