Indoor Air Quality

Indoor air quality (IAQ) is a combination of airborne particulates, microorganisms, volatile organic compounds, odors, and gasses, among others. Each is a combination of multiple elements and can include exhaust from diesel engines, smoke, fibers, hair, pollen, skin cells, insects, and fungi/mold.


We conduct IAQ investigations in offices, hospitals, educational facilities, municipal, state and federal buildings, and residential homes. Fuss & O’Neill’s highly trained staff systematically evaluates IAQ problems, provides ventilation and re-entrainment studies, assesses odors, and creates management plans.
