May Indoor Air Investigations, LLC
Tyngsborough, Massachusetts
May Indoor Air Investigations, LLC is a building and indoor air quality consulting firm based in Tyngsborough, Massachusetts, led by founder and principal scientist Jeffrey C. May. The company specializes in identifying indoor contaminants and their sources through detailed site investigations and advanced microscopy analysis. A distinguishing feature of the firm is that it analyzes its own dust samples in-house, reporting not only on mold spores but also on a wide range of other potential allergens including insect fecal matter, pet dander, pollen, and yeast — capabilities that most commercial laboratories do not offer. May Indoor Air Investigations provides services including site visits, phone consultations, renovation and construction advice, maintenance tips to minimize indoor allergens, report reviews, and expert witness work. Reports are individually composed, include photographs and photomicrographs, and combine site observations with actionable remediation and prevention advice. The firm operates independently with no financial arrangements with remediation companies or other service providers. Jeffrey C. May is the author of five books on indoor air quality published by The Johns Hopkins University Press and has been featured in The New York Times, the Chicago Tribune, Sports Illustrated, and Boston Business Journal, as well as on Good Morning America, CNN News, and Discovery Fitness and Health.
