August 7, 2026

Podcast Interview: Healthy Homes, Hidden Exposures & EMF Awareness - Building Biologist Jonathan Farrar

What if the place where you spend most of your time could be contributing to your overall environmental stress load?

DefenderShield CEO Kylen Ribeiro sits down with Jonathan Farrar, a Building Biologist, Certified Residential Mold Inspector (CRMI), and founder of JF Healthy Homes, to explore the connection between our indoor environments, electromagnetic fields (EMFs), mold, and healthier living spaces.

Jonathan Farrar is an environmental consultant, Certified Residential Mold Inspector (CRMI through ACAC), and Building Biologist specializing in healthier homes and indoor environments. His work was shaped not only through professional training, but through personal experience.

After becoming seriously ill and navigating challenges related to mold toxicity, Lyme disease, and environmental stressors, Jonathan began searching for answers that conventional approaches were unable to provide. His family’s own experience discovering mold contamination in their home became the catalyst for his mission to better understand the hidden factors that influence indoor environments.

Kylen Ribeiro is the CEO of DefenderShield, a women-owned company dedicated to EMF education, digital wellness, and developing science-informed products designed to help people create healthier relationships with technology. Through conversations with researchers, health professionals, and industry experts, Kylen helps bring important discussions around technology, wellness, and environmental awareness to a broader audience.

Key Takeaways:

What is Building Biology? Building biology looks at the relationship between people and their indoor environments, including factors like air quality, moisture, mold, building materials, chemicals, lighting, and electromagnetic fields.
A Personal Journey Into Healthier Homes. Jonathan’s path into building biology began through his own family’s experience with environmental health challenges, leading him to investigate the hidden factors within homes that may impact wellbeing.
Modern Homes Have Changed. Today’s homes contain more wireless technology than ever before — smart meters, WiFi devices, connected appliances, and cellular infrastructure — changing the electromagnetic landscape of where we live.
Every Home Environment Is Different. Apartments, townhomes, and shared-wall communities may present unique considerations due to neighboring WiFi networks, smart meters, wiring configurations, and proximity to other electrical sources.
The Relationship Between EMFs & Mold. Jonathan discusses his perspective on how electromagnetic environments may interact with other environmental stressors, including mold and indoor air quality concerns.
Protecting the Next Generation. Jonathan shares the practical steps he takes in his own home to create a healthier environment for his children and family. 💡 Feeling Overwhelmed? Start Small. Jonathan’s advice for those beginning their EMF awareness journey: focus on education, make gradual changes, and avoid feeling overwhelmed by trying to change everything at once.
Creating Healthier Spaces for the Future. The goal of building biology is not fear — it is awareness, understanding, and creating indoor environments that better support families, schools, workplaces, and communities.

Whether you are just beginning to explore EMF awareness or have been on your wellness journey for years, this conversation offers perspective, education, and practical steps for creating a more intentional living environment.
