Why You Shouldn’t Keep the Windows Completely Closed When Using Air Conditioning
Contrary to popular belief, the air in an enclosed room is not as clean as we think. Studies show that indoor air quality can be up to five times more polluted than outdoor air. Keeping the windows closed and running the air conditioner continuously for extended periods can lead to a stuffy and stagnant environment, increasing the risk of respiratory issues and fatigue, especially for children and the elderly.
Therefore, instead of sealing all openings, consider slightly opening a window or installing exhaust fans to facilitate air circulation. Additionally, opting for an air conditioner with air purification functions or investing in an air purifier is a wise choice for long-term health benefits.

Tips for Efficient and Safe Air Conditioner Usage:
1. Combine the Use of Fans: Running a fan at low speed helps distribute cool air evenly throughout the room, reducing the workload on the air conditioner, thereby saving energy and improving cooling efficiency.
2. Set Reasonable Temperatures: Instead of extremely low temperatures (16-20°C), maintain a comfortable range of 24-26°C. This temperature strikes a balance between comfort, energy conservation, and health considerations.
3. Opt for Energy-Efficient Models: Inverter technology in air conditioners automatically adjusts cooling capacity based on the actual room temperature, resulting in stable performance, reduced on-and-off cycles, and significant energy savings. This feature is especially advantageous during peak summer demand.

4. Regularly Clean or Replace Air Filters: Dirty air filters hinder the performance of your air conditioner, leading to increased energy consumption and potential air quality issues. For optimal performance and energy savings, clean or replace the filters every 2-3 months, especially during heavy usage.
5. Avoid Sealing the Room Completely: While it’s essential to close the doors and windows when using air conditioning to maintain the desired temperature, absolute sealing is detrimental. Leave a small gap or periodically open a window to allow for air circulation, improving indoor air quality and reducing respiratory problems associated with stuffy environments, especially in bedrooms.
6. Utilize Curtains and Insulation: Drawing the curtains or using insulating panels during intense sunlight can reduce heat penetration, lessening the burden on your air conditioner. This simple yet effective method maintains a comfortable indoor temperature while conserving energy.
