I have had this a week and it is very useful.  It has helped with the mildewy smell growing my apartment so much!  Such a relief that way. It is was all put together, easy to use. The noise is smooth and non bothersome.  The drying option has been really useful for me.  So far I am very happy with my purchase.  I also bought a warrenty extra.  I will try to update this after some time has passed
