Dudesky is correct.

The water collected in a dehumidifier is not potable and is full of all kinds of crap.

Distilled water is unadulterated water. No minerals or other reactants.

If you want to use the water collected in a dehumidifier, it is fine for plants or if you wanted to add car shampoo it's okay for washing your car. But don't drink it unless you thoroughly treat it, and don't give it to pets, either.
