Input:
I did a lot of research on humidifiers of this type before I bought and the only disclaimer I will add is that it does make an occasional "glugging" sound, which does not bother me since it is not in my bedroom.  I don't think it would wake me once I got used to it anyway.  Otherwise, it is very quiet even with the fan on high and takes no time at all to get my living space up to a decent humidity.  I have not bought new wicks yet, but I have seen them online for about $10.00, I think.  Also, after I bought the humidifier and it came in the mail, there was a small catalogue from the company that shipped it to me showing a cheaper price.  When I called them, they refunded the difference to my card.

I am thinking of buying a second one just like this one for next year.
