Misconception 1: Only use the range hood when frying, not when boiling water or cooking rice.
Solution: The range hood is not only useful for removing cooking fumes but also eliminates gas pollution, including gas leaks during ignition and extinguishing, as well as exhaust gases produced during gas combustion. Petroleum liquefied gas contains various strong carcinogens, which are more harmful to health than cooking fumes. Therefore, it is advisable to use the range hood even when boiling water or cooking rice.

Misconception 2: Only focusing on removing fumes and neglecting to replenish fresh air.
Solution: Along with expelling fumes, consider the overall ventilation of the room. Use an exhaust fan to supplement fresh air to ensure there is enough oxygen for gas combustion.

Misconception 3: The range hood is installed less than 70 cm above the stove, or it is installed above appliances that use solid fuels (such as coal, wood, etc.).
Solution: Such installation distances and methods may pose fire hazards. Ensure that the range hood is at least 70 cm above the stove and avoid using it above solid fuel-burning appliances.

Misconception 4: Cleaning plastic parts with alcohol solutions and wiping the surface with metal.
Solution: Alcohol solutions and metal can cause plastic parts and the surface of the range hood to lose their luster and get damaged. It is recommended to use mild detergents and soft cloths for cleaning.

Misconception 5: Only cleaning the grease filter every six months.
Solution:  If used daily, the filter should be cleaned every half a month to one month to maintain effective filtration.

Misconception 6: Believing that using the lowest fan setting saves the most electricity.
Solution: This is not always correct. Use the appropriate fan setting based on the amount of cooking fumes and actual needs to achieve the best fume extraction results without wasting electricity.

Maintenance Recommendations:

Regular Check-Ups: Check the motor and fan every three months for any abnormal sounds, which might indicate loose parts or obstructions.
Professional Repairs: If the motor shows signs of difficulty rotating or wear, contact a professional service for a thorough inspection and necessary part replacements to avoid more serious mechanical failures.

Energy-Saving Suggestions:

Utilize Smart Features: Many modern range hoods are equipped with smart control systems that can save energy, such as automatic shut-off and adjustable speeds.

Timely Shut-Off: Use the delay shut-off feature to allow the range hood to continue operating for 5-10 minutes after cooking to thoroughly clear any residual fumes.

Regular Professional Inspections:

Deep Cleaning: It’s advised to have a professional deep clean and inspection at least once a year, especially focusing on the internal ductwork and filtration system to maintain optimal suction and hygiene.

Suitable Cleaning Products:

Recommended Products: Provide recommendations for well-reviewed cleaning agents specifically designed for range hoods, which are gentler on the appliance and more effective.

DIY Cleaners: You can also use household items like vinegar and baking soda to create economical and environmentally friendly cleaning solutions.

Handling Issues:

Common Fault Diagnosis: Teach users how to diagnose common faults with their range hoods, such as checking if the power supply is connected properly or if the filter is clogged.

Emergency Measures: If difficulties in starting or decreased smoke extraction efficiency occur, it is recommended to stop the machine immediately for inspection, and contact maintenance if necessary, to avoid prolonged damage to the machine.
