June is National Healthy Homes month – and with the current crisis, homeowners are showing a renewed, growing interest in healthy, virus-free homes. As a result, there is a LOT of information out there about how to address these concerns, and trying to navigate through it all can be challenging and overwhelming. In this webinar, we spoke with Energy Vanguard's Allison Bailes and Jeffrey Sauls about practical ways to help your customers create healthier homes they feel good about living in. Allison and Jeffrey discussed what works and what doesn't when it comes to indoor air quality (IAQ) measures including filtration, UV lights, and more.
