  • The outdoor conditions High humidity, windy, dense plantation, causes the moulds spore concentration are higher than other area. High humidity leads to a prone condition for HDB units to be attacked by moulds growth.
  • Furniture moisture contents The black veneer wood furniture and teakwood door have quite high moisture content 20% (above the average standard). It is concluded that the furniture is categorized “wet” and need to be dry up.
    • Remove moulds growth by wiping or vacuuming the surface. Vacuuming should be conducted with a wet –dry vacuum and the filter should be replaced. Those cleaning should be done outdoor.
