Beat Hong Kong's Humidity: 3 Key Tips - 1
Hong Kong's climate is humid all year round, making it extremely prone to mold. Whether you are a homeowner or a tenant, moisture-proofing and mold removal are daily tasks that cannot be overlooked. Whether it's mold in the corners of your walls, a smelly wardrobe, or the discomfort caused by heavy, humid air, mastering a few correct methods can greatly improve your living environment and reduce health and property damage.

Below are 3 practical key points compiled for you, from dehumidifying and ventilating to daily maintenance, to help you keep your home dry and clean even in Hong Kong's humid weather.

Correct Usage of Dehumidifier

  • Close windows when dehumidifying: When using a dehumidifier, close the doors and windows to prevent external moisture from affecting the efficiency
  • Recommended humidity setting: Set the target humidity to 50%～60%, which is most effective in preventing mold and maintaining comfort
  • Concentrated use: It is most effective to dehumidify one room at a time; simultaneous use in multiple rooms is not recommended
  • Recommended time frame: Dehumidify for about 3～6 hours daily, no need to keep the machine on all day; turn it off when leaving home
  • Regular maintenance: Regularly clean the filter and empty the water tank to avoid bacterial growth

Ventilation and Exhaust Fan Usage Tips

  • Timing Matters When Opening Windows: Open windows during sunny or dry midday hours, and close them in the early morning, evening, or during rain to prevent moisture
  • Create Cross Ventilation: Opening windows on opposite sides can enhance air circulation, helping to expel dampness
  • Correct Way to Use Exhaust Fans:
    • When in use, close the windows and leave a door slightly open to allow dry air to replenish indoor air and speed up moisture removal
    • Turn on the exhaust fan immediately after cooking in the kitchen or showering in the bathroom to remove steam
    • Clean the filter and fan blades once a month to prevent a decrease in airflow

Handling Mold Spots and Daily Mold Prevention

  • Cleaning Mold Spots: If mold spots are found on corners of walls, the back of wardrobes, or ceilings, you can use 1:1 white vinegar water or diluted bleach to spray on the mold spots, leave it for 10 minutes, then scrub off and wipe dry
  • Keep Dry and Ventilated: After removing mold spots, ensure the area remains ventilated and dry, using a circulating fan or dehumidifier if necessary
  • Prevent Mold Recurrence: Applying anti-mold tape or anti-mold paint in areas prone to mold can help extend the cleaning effect
