Ava Heartwell

I’m Ava Hartwell, and I created IndoorAirInsights.com after surviving something I never imagined could happen in a brand-new, “dream” custom home. Hidden leaks, poor construction, and months of mysterious symptoms I couldn’t explain eventually revealed the truth: my house was making me sick. What followed was a long, messy, emotional fight to understand mold, environmental toxins, and what it takes to reclaim your health when your own home becomes unsafe. Today, I write to help you avoid what I went through—or navigate it with far more clarity than I ever had. My work blends lived experience, research, practical guidance, and the raw honesty I wish someone had given me in the beginning. Whether you’re dealing with mold, unexplained symptoms, or just trying to create a healthier home for your family, you’re not alone here. I’ve walked this road, and I’m determined to make it easier for the next person who has to.

The Worst States in the U.S. for Mold Exposure — And Why This Isn’t Talked About Enough

Where you live in the U.S. plays a much bigger role in mold exposure than most people realize. Climate, housing construction, humidity, storms, and even building culture all matter. After what my family went through, I stopped believing mold is just a “home maintenance issue.” In this post, I share my opinion on the worst states for mold exposure — and why residents in these areas are often gaslit when their symptoms don’t make sense.

Why I Don’t Believe “A Little Mold Is Harmless” Anymore

I used to believe what everyone says — that a little mold is normal, harmless, and nothing to worry about. Doctors said it. Inspectors shrugged it off. Friends repeated it. But after watching my health unravel and my kids change inside our own home, I can’t say that anymore. This post explains why the “harmless mold” narrative is deeply misleading, who it protects, and what I wish I’d questioned sooner.

I used to think mold coming back meant I hadn’t cleaned well enough. I scrubbed harder, tried different products, and blamed myself when it returned. What I didn’t understand yet was that recurring mold isn’t a cleaning failure — it’s a moisture problem. In this post, I explain why mold keeps coming back, the mistakes I made, and what actually stopped the cycle in my own home.
