Q: Why is there white powder around the humidifier?
A: Tap water contains minerals that can adhere to objects.
We recommend using purified or distilled water to fill the humidifier. Avoid using
water with high mineral content, such as tap water. Clean the water tank regularly
and keep precision instruments away from the humidifier to avoid damage.
Q: Why is there scale in the water sink or tank?
A: Tap water contains minerals that can adhere to objects. Clean the water sink and
tank regularly.
Q: Little or no mist comes out.
A: There could be several reasons, such as unclean water, a dirty atomizer plate,
or a clogged air intake. Clean the atomizer plate, replace the water with clean
water, and then check if the air inlet is blocked.
Q: Why is there unusual noise?
A: There could be too little water or the humidifier may be placed on an unstable
surface. Place the humidifier on a solid and sturdy surface and fill the water tank
with water.
Q: Why is the red light flashing?
A: Open the sink and check whether the water can be pumped up.
If not, disassemble the water pump and water pipe and install them again (see
page 14). If neither of these is the issue, please contact customer service to get
replacement pump via email.
Troubleshooting
17
Q: Why does display show an incorrect humidity percentage?
A: Moisture may have built up the humidity sensor. Please dry the sensor with a cloth
or air dry it first.
The humidity sensor will give an improper reading if it is exposed to dust. Avoid
using the humidifier in dusty rooms. Avoid using tap water in the humidifier as this
can increase dust in the air.
Please note that the humidity sensor and hygrometer in the room may have an
error range of 5-10% depending on the sensing method and structure.
If neither of these is the issue, please contact cusstomer service to get
replacement pump via email.
Q: Why is the floor wet or there is water around the humidifier?
A: The humidity may be too high or the humidifier may be placed in a non-ventilated
area, causing the mist to not fully evaporate.
Q: Why is there interference with the TV remote control signal?
A: Keep the humidifier at least 1 meter away from the TV or other objects that emit
radio waves.
Q: Why is the fire on the stove turning red?
*If your problem is not listed, please contact Customer Support.
A: The composition of tap water can react with the flame, so keep the humidifier
away from the stove.
