Don't buy this fan from wayfair. Wayfair sent me a broken fan. When I called them they said they could not help me and told me I needed to contact dyson directly. When I called dyson they told me the fan had already been registered by someone else and would not help me. 4 hours on the phone and I'm still trying to get the item replaced or get my money back...when a nightmare. Shame on wayfair and dyson. I thought these were respectable companies but I guess not, don't waste your time
