Whole house dehumidifiers can maintain indoor humidity at a consistent 40% to prevent mold growth.

“So, whole house dehumidifiers are a game changer. So, if you're going to live in a drywall box like I am and you can't live in open air like Dr. Paul, then maybe you need whole house dehumidifiers. So, that's what we have in a brand called Aprilaire. I'm not endorsing them. I'm not affiliated with them. That's just the brand we have and they've worked really well. What they do is they hook up to your ductwork. So, in our basement in the unfinished space, we have these whole house dehumidifiers that hook up to your ductwork. I set them to 40% My house is perfectly at 40% humidity, never a percent higher and if it goes a percent higher, they kick on, they suck the moisture out, it runs a tube outside of the house to drip that moisture out of the house.”

“So, that's why whole house dehumidifiers in most of the country, in my opinion, are are necessary building strategies.”
