*Return Policy: There are no returns if the wrong size is ordered. Appolo Heating is happy to assist customers in identifying which size to order for their furnace, but cannot offer refunds on wrong sizes. If a filter comes shipped damaged, then customers can make a claim for a refund or refuse shipment and will be compensated with a new filter at no charge. If customers ordered the correct filter and the wrong filter shipped, they will also be able to receive the correct filter at no additional cost.
