Low noise: The main component of the electric fan making noise is the motor. When choosing an electric fan, be sure to listen to whether there is noise when the motor is running, whether there is vibration during operation, and whether it is stable; a good motor can allow you to run in a quiet environment. Only the "whisper" sound of the wind can be heard in the middle, and the ultra-quiet air supply is a good fan.

No peculiar smell: The peculiar smell is caused by the insulating paint on the copper surface when the electric fan is running. When buying an electric fan, be sure to smell it to see if the paint is environmentally friendly and has passed the quality inspection to make you feel refreshed. Feel the coolness of the wind in the air.

Electrical safety: There are very detailed regulations on the safety requirements of electric fans in national standards, and consumers can also conduct simple tests. For qualified fans, the fingers of an adult cannot reach the leading edge of the fan blades through the grille. Families with children should choose electric fans with tighter grilles.
