Solar Sun Power Mini Air Conditioner For Car Car Window Auto Air Vent Cool Fan Portable Car Air Conditioner Ventilation

I was quite surprised when this arrived because I thought it was completely new. It was filthy! How am I expected to use this for air vent and air conditioning when it's dusty? I attempted to return but the seller hasn't responded or refunded me. I'm pregnant so I can't take risks to install something like this when I have no idea what disgusting environment it has been in.
