Dehumidifying material

SIO₂ (silica gel)


  • This mini dehumidifier is ideal for small and compact spaces, such as wardrobes and cabinets.
  • Simply place the renewed SiO2 Cylinder in the desired area and it will dehumidify the area constantly until it reaches its capacity (100ml).
  • The base is for renewing the SiO2 Cylinder only. You do not need the base for dehumidification.


  • Check whether the power cord is in good condition.
  • Check the color of SiO2 in the display window. Orange: no need for renewing; Dark green: need to renew.
  • Make sure the voltage of the power socket is consistent with the input voltage of the base.

Renewing SiO2 Cylinder
Renewing SiO2 Cylinder

  1. Once the base is powered on, the indicator flashes white light (stand-by mode). Insert the cylinder to the base and the indicator turns solid green (renewing mode).
  2. One renewing cycle is 2 hours. Once the 2-hour cycle is completed, the indicator will switch to flashing white.
  3. Check the color of SiO2 in the display window. If it’s not orange, pick up the cylinder from the base for more than 3 seconds and put it back to the base for another cycle.
  4. Unplug the base once the cylinder is renewed.


  1. The moisture absorption time will be affected by the ambient humidity..
  2. The more humid the ambiance is, the longer time it needs for the base to renew the SiO2 cylinder. If the color of the SiO2 in the display window hasn’t turned back to orange after one renewing cycle (2 hours, the indicator: flashing white), it means the cylinder is not completely renewed (dry). Pick up the cylinder from the base for more than 3 seconds and put it back to the base for another cycle. You may pick up the cylinder once the SiO2 turns orange.
  3. If you pick up the cylinder during the 2-hour cycle, the base will keep running for one minute. It is to release the residual heat from the base. After one minute, the base switches to stand-by mode (the indicator: flashing white).
