Ian Cull, P.E.
Author, Speaker, Chicago's air quality expert

Typically, when you hire a company to test your air quality, a “technician” will arrive. Even worse, a salesman may arrive with an ulterior motive… trying to sell you on needless antimicrobial sprays, duct cleaning or remediation that will cost you tens of thousands of dollars.


Avoid the scams by going with the most trustworthy option: hiring Chicago’s top air quality expert, Ian Cull. He has no products to sell or hidden conflicts of interest. When your health is being affected by poor air quality, you should only trust the best. Have Ian Cull personally come out to your home, office or school to give you expert advice.
