Midea has issued a recall for about 1.7 million of its U and U+ shaped window air conditioners due to potential mold growth that poses health risks, including respiratory issues. The recall affects nearly 2 million units sold through major retailers in the U.S. and Canada. Consumers are advised to check if their air conditioner is affected and to follow the necessary steps for a free repair or refund. This safety measure comes after reports linking mold exposure to respiratory problems, prompting urgent action from the manufacturer.
