There's such a thing as botulism ; so - once the toxin causing it has formed, it doesn't matter that you kill the bacteria that produced it with boiling the water. The toxin itself survives much harsher conditions.

I think it's not the only danger which you haven't considered here.

    Y'all, we're talking about condensate from a device specifically designed to capture water for drinking. We're not talking about drinking the water dripping from your AC. Ensuring this water is drinkable is remarkably simple.

    Not only that, but Clostridium botulinum only grows in anaerobic environments, so it isn't even a remote concern in this case. That's why you don't hear about it much outside of canned food or instances where it's purposefully cultivated for medical applications.

    Well, if this idea is so glorious, why is none of the large array of water harvesting devices that pop up multiple times a year ever deployed at scale?

    Easy answer: because they are all marketing bullshit that doesn't solve the actual problem and instead only exists to part investors from their cash.
