Stefan Irwanto | Mould, Mycotoxins, VOCs, EMF, Lead Testing.

At Test My Property, the goal is simple—to help Victorians breathe easier and live safer at home. My name is Stefan Irwanto, and after twenty years in biomedical engineering and environmental monitoring, I’ve dedicated my work to making indoor spaces healthier for everyone.

My journey began by helping design and manage air quality networks for public health agencies, including rapid deployment systems for bushfire smoke across Victoria. I am personally sensitive to both mould and electromagnetic fields (EMF), so I understand just how much indoor exposures can impact wellbeing. This lived experience drives my commitment to finding practical solutions for mould, air quality, EMF, and building biology assessments.

I hold Bachelor of Biomedical Engineering from RMIT University and an Advanced Diploma of Building Biology from the Australian College of Environmental Studies (ACES). I am currently undertaking a Master of Occupational Hygiene and Toxicology, building advanced capabilities to evaluate and reduce exposure risks in a variety of environments.

Test My Property also recognizes the importance of international standards, which is why I maintain council-certified credentials through the American Council for Accredited Certification (ACAC).

Test My Property serves Greater Melbourne and all of Victoria, focusing on thorough assessment, transparent reporting, and one goal: improving environmental health, one property at a time.
