Abstract
A duct-free air filtration system including a housing having a hood for capturing air, grease, and smoke, and an elongated exhaust section in fluid communication with the hood. A grease extracting blower unit takes in air, grease, and smoke through the hood and exhausts air and smoke through the exhaust section of the housing with a substantial amount of the grease removed by centrifugal force. A charcoal filter disposed in the exhaust section removes odors from the air exhausted from the grease extracting blower unit and a smoke filter removes smoke from the air passed through the charcoal filter.
