I'm pretty sure that everyone is going to say that RO/DI is the way to go, but I was wondering if the water collected from my dehumidifier would be almost as pure. Isn't it essentially taking pure water out of the atmosphere? Would it at least be better than tap water? I don't have a TDS meter, so I can't say with all certainty that the water would be pure.
