Water Filling

There are two ways to add water.
● Please add water below 40°C.
● Distilled water or RO water is recommended.
● Please do not exceed the maximum water mark.
● Please do not allow water to enter the mist outlet, or water may enter the inside and cause
the machine to malfunction.
● Please do not add mineral water, plasma water or tap water that has not been used for
a long time. If mold or impurities grow, it may cause health problems.
● When the water is insufficient, the machine will prompt water shortage and automatically
shut down. Please refill with water and turn it on.
● Regarding water accumulation in the base: The humidifier uses ultrasonic vibration of the misting
plate to disperse liquid water into a mist. The water tank is merely a transitional water storage
tool, and all humidifiers' base reservoirs will accumulate water. Please use it with confidence.
Note
Open the top cover of the main unit
to add water.
Do not exceed the
full water line(MAX).
Remove the main body and add
water to the water tank directly.

or a clogged air intake. Clean the atomizer plate, replace the water with clean
water, and then check if the air inlet is blocked.
