According to Prof. Dr. Nguyen Truong Luyen – former staff of the Institute of Technical Physics (Hanoi University of Science and Technology), the risk of electric shock and fire from the ventilation fan can occur after a period of use or incorrect installation. Therefore, people should also regularly check whether the exhaust fan is functioning normally. If the fan makes strange noises, it needs attention.
Usually, ventilation fans, exhaust fans are installed in high and hidden places, so most people pay little attention to them. Moreover, people often think that ventilation fans do not need to be cleaned because the fans help remove dust.
However, ventilation fans are like other ordinary fans that need to be cleaned regularly to protect the fan. Failure to regularly clean not only affects the equipment but also poses a risk of fire due to overheating, affecting the air filtration process. Especially in the kitchen area, the fan is easily coated with grease. When the fan is turned on and does not work, it may lead to a fire.

+ After turning off the power, remove the outer cover of the ventilation fan. Since it is usually located at high positions, users will need to use a ladder or a sturdy chair to do this work. Besides, if you can prepare an object to catch the dust falling from the fan, it’s even better.
+ Then remove the fan from the holder. It needs to be done carefully to avoid dropping the fan from above as it can damage the fan blades, break them, make the fan noisy, or work inefficiently.
+ Use a vacuum cleaner or lower it under a water tap, then use a soft cloth to clean the dirt. Users can also dilute soap with water to clean the dust. For the fan housing, a soft cloth can be used for cleaning. Before reinstalling, the fan blades should be wiped or dried.
In the case of a ventilation fan in the kitchen area prone to grease, you can use sawdust for cleaning.

In areas that are obstructed, you should use cotton swabs for cleaning.
