Frigidaire produces a diverse selection of products under both the Frigidaire and Electrolux brand names. Additionally, they manufacture items for the Sears-Kenmore line. One of their innovations, the Frigidaire PureAir® Refrigerator Air Filter, employs activated carbon, Zeolite, and baking soda to effectively reduce odors from potent foods such as onions, garlic, fish, spoiled milk, and overly ripe produce. To maintain optimal performance, it is advised to replace the air filter biannually. The filter dimensions are 4.5 inches by 2.5 inches.
