Could the materials in your home be releasing harmful chemicals into the air you breathe? In part one of this two-part interview, Andy Pace exposes the hidden toxins in your walls, floors, and furniture—volatile organic compounds (VOCs) and hazardous air pollutants (HAPs). Andy explains how modern energy-efficient designs have contributed to “sick building syndrome,” why “zero VOC” labels and certain air-purifying methods don’t always mean healthier air, and how off-gassing continues long after that new paint smell fades. 

From the history behind the green building movement to choosing the best low-toxin materials, this episode is filled with expert tips to help you create a healthier home even for the most chemically sensitive residents. If you want clean indoor air, it’s time to get nosy about VOCs and HAPs!

Episode Highlights:

What are the different types of VOCs and how do they enter our homes? 

22:47

What is formaldehyde, and how does it get into homes? 

27:27
