Exhaust fans are the exit point of your kitchen’s exhaust system. Over time, the grease vapors that bypass the filters in the hood system, build up within the duct and up through the blades of the exhaust fan. While the purpose of the fan is to extract the air, the build-up should be removed regularly.
Several factors will determine the cleaning frequency, such as:
- The cooking frequency and type of food being cooked.
- The amount (total length) and design of the duct work
- The type of fan, its components, and housing
