When added to Aget's existing filter units, a new series of HEPA filters creates a third stage of cleaning, allowing heated or conditioned air to be safely re-circulated back into a building. The filters also help balance building air pressures and enhance energy efficiency while reducing the need for makeup air. The HEPA filters are tested and certified to remove 99.97 percent of contaminants at 0.3-micron size; the filters trap and remove dust, bacteria and allergens from the returned air.
