Product review (4 stars): I added the recommended amount to my humidifier tank
This review is primarily based on my trust in the claims made by sunbeam regarding elimination of bacteria. I added the recommended amount to my humidifier tank, and then let the humdifier run outside until dry.  Apparently you can run it inside with the chemicals inside, but I am a bit leery about doing that. I figure it gets just as clean outdoors and I am not risking breathing in potentially harmful chemicals.
