As a chemist I had to check out the 'chemistry' section of Yahoo questions. I figured I would tackle a few questions as a way to repay the folks that have been answering my 'lawn and garden' questions. I do believe that we chemists are doing the homework for the next batch of chem graduates. I hope they are thinking about their questions critically and not blindly posting them.

This is really an inappropriate post, but this seemed to be the place to hit the right audience.

Be well all,

Assuming the unit is clean and has been disinfected with bleach periodically, is there anything inherent in the process by which a typical room dehumidifier works to preclude safely drinking the water it extracts from the air? Is the water essentially w/o additional minerals and chemicals found tap and well water? The only thing that comes to mind for me is that there might be some lead welds somewhere . . . sorta like the old problem of using car radiators in alcohol stills.
