2.To avoid the phenomena such as too high noises or vibration, or oil dripping/leak of range hoods. Range hoods shall be cleaned regularly so as to prevent excessive oil from adhering to the motor, turbine, and the inner surface of the range hood.

3.Rated power of the light bulb for replacement must not exceed the maximum value indicated aside the lamp stand and in the instruction manual; otherwise, temperature rise of the connecting wires and lamp stand may get too high and lead to earlier aging of insulating layer of the wires, resulting in potential hazard of electric shock, or even a fire.

4. Ask: How to maintain a range hood?

Answer: 

Range hood components should be cleaned and replaced regularly. The hoods need to be cleaned by a professional cleaning product. The aluminum filter need to be washed periodically. Consumers who fry their foods more should clean the filter more frequently. 

After a certain number of usage, the filter may get clogged, and it’s suggested to replace every three months. A ductless range hood can’t reach its ideal function without the clean filter.

Most fan motors of the vent hood don't need any maintenance. But it’s possible that the motor and bearings may get stiff because of the constant heat, humidity, grease, and so on. After long time use, it’s also possible that the blower wheel gets greasy and dirty, which can slow down the fan or cause vibration. To remove the wheel and clean it with a degreaser, after that, if the fan still works slowly or vibrates, you need replace the fan motor by a professional technician.

5. Ask: How to deal with the ducting when installation?

Answer: 

The purpose of hood ventilation is to exhale the air outside, so please make the path as simple as possible. 

The ventilation system is the most efficient when the duct is short and straight. If bends are inevitable, try to limit the angles to 45 degrees, because the air loses its momentum when hitting a right angle turn. 

Cleaning the interior of the vent hood with a standard household degreaser/cleaner.

6. Ask: How to choose a range hood?

Answer:

1) Width: Everybody cooks once in a while. In order to prevent the smell and haziness from spreading, your range hood should be at least as wide as the stove.

3) Material: Basically, you can choose either painting or stainless steel, which is base on your preference.

4) Airflow or Suction Power: It’s available from the low speed to the high one, which is decided by your cooking area and your preference.

5) Appearance: It’s recommended that the range hood design should match the style of your kitchen.
