Unfortunately, I had to return this rug because there was a very strong musty smell that you could smell even when it arrived being wrapped in a double plastic.  I opened the rug and left it for a day but unfortunately the smell permeated the room and up the hallway so badly that we had to put fans on.  Disappointing as I have purchased two other rugs from Wayfair without this issue, however, this one definitely had to be returned.
