Product review (2 stars): I would not use this indoor in any situation.
the product itself is decently built.  However, I would not use this indoor in any situation. Even in a room with a fan this puts out far to much moisture.  The product does work but over time you will see problems because of the moisture.  my washer and dryer are in the garage and I will not continue to use it for fear of  ruining my walls. you can imagine what it would do to a small indoor laundry room or apartment.
