Midea is recalling 1.7 million air conditioning units because a drainage problem could expose consumers to mold. Water can pool in the appliance maker's U Window Air Conditioner and U+ Window Air Conditioner units, possibly leading to mold growth. Mold can cause respiratory issues and other infections. The CPSC has received at least 152 reports of mold buildup in the Midea AC units. 17 consumers experienced respiratory infections, allergic reactions, coughing and sneezing, or sore throats as a result of mold exposure. Along with the units sold in the US, nearly 46,000 were sold in Canada. The Midea products were sold under a range of brand names, including Comfort Aire, Danby, Frigidaire, Insignia, Keystone, LBG Products, Mr. Cool, Perfect Aire and Sea Breeze, according to the recall notice. A range of makes and models, measuring 22 inches wide by 14 inches high, are under recall. Midea toll-free number: (888) 345-0256.
