Abstract: An air conditioner exhaust cover including a mesh covering with an outer perimeter, the mesh covering configured to reversibly and completely cover the exhaust opening of an air conditioner, and further configured to allow exhaust to be vented from the exhaust opening, and further configured to block debris from entering the exhaust opening. The cover includes a reinforced border located at the outer perimeter of the mesh covering, into which a plurality of attachment points is formed. The covering system also includes a plurality of flexible attachments each comprising a proximal end and a distal end, the proximal end configured to attach to at least one of the plurality of attachment points, and the distal end configured to attach to another point that at least partially stretches the flexible attachment to hold the mesh covering in place over the exhaust opening of the air conditioner.
