1. Operate the space heater for 2 - 3 hours at a time
Make sure to run the heater continuously for 2 - 4 hours and then turn it off for about 30 minutes to prevent motor overload, overheating, decrease in heater lifespan, and reduce the risk of fire or explosion. Alternatively, you can opt for models with auto shut-off features when overheating occurs for added safety.

2. Avoid sealing off the room when using a space heater
A common misconception during cold weather is to seal off rooms tightly to retain heat. However, keeping the room tightly sealed will lead to dry and overheated air, hindering air circulation. People inside the room will end up breathing in the same hot and exhaled air, resulting in stuffiness and lack of fresh air. It's advisable to crack open a window or use a fan for ventilation while using heaters or air conditioners.

Ensure Proper Ventilation
3. Avoid setting the temperature too high
According to experts, during extremely cold days, it's advisable not to set the temperature too high, avoiding a significant difference between indoor and outdoor temperatures to prevent sudden cold exposure when stepping outside.
For our climate, maintaining a temperature between 22 to 25 degrees Celsius is ideal. Excessively hot and dry air can adversely affect the respiratory system.
4. Keep space heaters at a safe distance when sleeping
Space heaters emit intense heat, especially when set to the highest setting. Placing the heater too close to your body while sleeping may not be safe for your skin and respiratory system. Therefore, it's recommended to maintain a safe distance of 1.5 - 2 meters away from the bed or individuals when using a heater during sleep.
5. Place a bowl of water in the room
To increase humidity in the air and reduce the risk of dry skin and eyes when using a heater fan, you should opt for models that have humidity balancing functions or simply place a clean water basin in the room. Alternatively, if the air is too dry, consider using a humidifier.

6. Pay close attention to usage instructions.
The general principle before using electrical products is to carefully read the instructions, and heater fans are no exception. Users need to take the time to study the technical specifications of the device to ensure safety.

The necessary technical specifications to grasp (which are also common specifications) include power level, heat level, distance.... Additionally, you should pay attention to some things after using a heater fan:
- - Avoid placing heater fans near the sleeping area to ensure safety.
- Avoid placing heater fans near flammable objects such as curtains, drapes, or furniture.
