The system can function in air with 20% humidity or less. But these 1,000 liter a day machines are not small, at around shipping container size.

It really comes down to what you mean by humidity. “Dew point” can be negative, but humidity cannot.

“Negative humidity” is like saying “this glass has so little water in it, it has negative water”.

Weather channel negative humidity... either way, it's a far cry from the 20% this thing seems to be designed for.

Yes. I drink it and I actually lose water.
