Classification of de-humidifier tank water?

[Tsuchibuta]

I know your first thought is why are you running a de-humidifier while trying to grow orchids. Well my wife thinks that it's unacceptable that her sweaters mold.

So with that being said, my thought is that the drain water would be similar to distilled water. Do you think this is accurate? I don't have a tester to test the dissolved solids so best guess is acceptable to me.
