How Humidifiers Avoid Mold for HVAC Pros Using Water Activity and RH Science with Marlee and Montana

In this episode of the HVAC Know It All Podcast, host Gary McCreadie talks with Marlee Spiegelberg and Montana McElwain from Condair USA/CA about mold, humidity, and air quality. They explain what the water activity factor is and how it connects to mold growth. They also talk about keeping homes and buildings safe by controlling humidity. Their goal is to clear up common fears about mold and show better ways to manage air quality.

Marlee and Montana explain why people are often scared of mold when it's not always a big danger. They talk about how keeping the right humidity can stop mold from growing. They also share how new technology helps control air quality better. Good control systems can protect homes, businesses, and even hospitals by keeping the air safe and healthy.

Throughout this episode, Marlee and Montana talk about why managing humidity the right way is so important. They explain that using the right systems and keeping moisture levels steady helps prevent mold and keeps buildings healthy over time.
