Abstract

Abstract A roll of disposable filter sheeting is located at the upper end of the air discharge side of the air conditioner chassis. Two rolls of adhesive sheets are located at the lower end of the discharge side. The filter is drawn down to cover the discharge opening and out through a slot at the bottom of the chassis. The adhesive sheets from the two rolls come into contact with opposite sides of the filter as it comes out of the chassis and cover the used filter portion, when said used portion is drawn down to cover the discharge opening with a fresh, clean portion of filter. The withdrawn piece of filter being covered on both sides may be withdrawn and severed and disposed of without dirtying the hands of the operator.
