Any particulate that gets caught up in the dehumidifier could be in the condensed water... Really depends on whats in your air.
Conceptually, it could/would be perfectly be fine, but anything floating around (cleaning agents, etc.) could be caught up in the condensate.
A few years ago another site had a very long thread about this topic...seems to me the majority felt the risk of copper problems and the potential for introducing toxins were major problems. I can't remember all the specifics...but as i remember the thread most folks felt it wasn't a good idea.
I thought the condensed water only comes in contact with the exterior of the condensor fins which I think are aluminum. If this is correct, does trace amounts of aluminum pose a risk for using the water in a quarantine tank?
Thanks, I had a feeling aluminum would be bad but had to ask anyway. I also didn't think about air freshners and my wife does use them. Guess I'll just keep pouring the dehum. water down the drain.
