Yes, range hoods can be operated without an exhaust duct by using a ductless or recirculating range hood. These types of range hoods use filters to capture grease and odors, and then recirculate the air back into the kitchen. While they are not as effective as ducted range hoods at removing cooking byproducts from the air, they can still help improve indoor air quality and reduce odors in the kitchen. However, it's important to regularly clean and replace the filters in a ductless range hood to maintain its effectiveness. **

To clean ventilation systems, especially exhaust hoods in restaurants, you should start by turning off the system to ensure safety. Remove any filters or grease traps and soak them in warm, soapy water to loosen the grease buildup. Use a degreaser to clean the interior and exterior of the hood, as well as the fan blades. Wipe down all surfaces with a clean cloth and replace the filters once they are dry. Regular cleaning and maintenance of ventilation systems are crucial to prevent fire hazards and ensure proper functioning. **
