Frequently Asked Questions：
Q: What are the main types of electric fans?
A: Common types include Pedestal Fans (stand on an adjustable-height pole), Tower Fans (tall, vertical, space-saving), Desk/Table Fans (small, for personal use), Box Fans (rectangular, often placed in windows), Ceiling Fans (mounted overhead), and Wall-Mounted Fans (fixed to a wall).

Q: Is it safe to leave a fan running all night or unattended?
A: Modern fans designed for continuous operation are generally safe if placed stably with good airflow and away from flammable materials. However, it's always recommended to follow the manufacturer's instructions. Never leave a fan unattended with children or pets who might poke objects into the grille.

Q: How do I clean my electric fan?
A: Unplug the fan first! Wipe the exterior with a damp cloth. For blades and the front/rear grilles (if removable), use a soft brush (like a paintbrush), vacuum cleaner attachment, or compressed air to remove dust. Wash removable grilles and plastic blade covers (if applicable) with mild soapy water, rinse thoroughly, and dry completely before reassembly.

Q: Does using a fan actually cool the air?
A: No, fans do not lower the air temperature. They create a wind-chill effect by moving air across your skin, which helps evaporate sweat and makes you feel cooler. They are effective for personal comfort but won't cool a room like an air conditioner. Q: Why isn't my fan oscillating (swiveling side-to-side)? A: Check: 1) If there's an oscillation button/switch, ensure it's turned on. 2) Gently try to start the oscillation by hand – sometimes gears can stick if not used for a while. 3) Ensure nothing is physically blocking the fan's movement. 4) The internal oscillation mechanism might be broken or disconnected, requiring repair.

Q: Do fans use a lot of electricity?
A: Generally, no. Fans are significantly more energy-efficient than air conditioners. A typical household fan might use between 15 to 100 watts depending on size and speed setting, costing only pennies per hour to run, making them a cost-effective cooling option.
