      They didn’t have an AC compressor, refrigerant, etc. Their system stops working when your humidity is too high.

      It works on the same physical principle, but they’re still very different in their usage, side effects and limitations.

      Well a significant difference is that this increases humidity, while normal AC decreases it.
