• Always make sure to place the
humidifier on a flat, level surface before
operation.
• Only fill the water tank with clean water.
Never fill the water tank with any other
liquids.
• Do not place the humidifier near
sources of heat, such as stovetops,
ovens, or radiators.
• Do not place the humidifier directly on
floors, carpets, or rugs.
To reduce the risk of fire, electric shock, or other injury, follow all instructions and
safety guidelines.
General Safety • Do not use other items as replacement
parts for this product.

the humidifier.
• Remove the water tank from the base
before moving the humidifier.
• Do not immerse the humidifier base,

• Ensure that the plug fits properly into a
polarized socket.
• Do not handle the power cord or plug
with wet hands. Keep the plug and power
cord away from liquids.
• Your humidifier has a polarized plug (one
prong is wider than the other), which fits
into a polarized outlet only one way. This
is a safety feature to reduce the risk of
electric shock. If the plug does not fit,
reverse the plug. If it still does not fit,
do not use the plug in that outlet. Do not
bypass this safety feature.
• If the power supply cord is damaged, it
must be replaced by Arovast Corporation
or similarly qualified persons in order to
avoid an electric or fire hazard. Please
contact Customer Support
(see page 27).
• Unplugging the power cord will disable
remote control of the humidifier and
temporarily disconnect the humidifier
from VeSync and other third-party apps.
This humidifier complies with all standards
regarding electromagnetic fields (EMF).
If handled properly and according to
the instructions in this user manual, the
appliance is safe to use based on scientific
evidence available today.

Note: Check to make sure that the
water filter is correctly in place. If not,
then rotate the filter clockwise to secure
it in place.
Note: The humidity sensor and an air

humidifier at least 12 inches / 30 cm away
from any walls. The surface must be
water-resistant. [Figure 1.1]
• Do not place the humidifier directly
on floors, carpets, or rugs.
4. Mist should be directed away from walls,
furniture, bedding, and appliances. Avoid
letting too much mist fall on the side of

Your humidifier must have the correct level
of water in the base chamber to work
properly. If there is too much water in the
base chamber, the humidifier cannot create
mist.
Figure 4.1
IMPORTANT TIPS
• Do not place the humidifier on an
inclined surface.
• Never pour water directly into the
base chamber. [Figure 4.1] Only add
water to the water tank. The humidifier
will automatically release the correct
amount of water into the base chamber.
• Avoid moving or shaking the humidifier.
This may cause the water tank to
release too much water into the base
chamber.
• Before moving the humidifier, turn it o,
unplug it, and remove the water tank.
Empty any excess water from the base
chamber.
Note: If you’ve been using the warm
mist setting, allow the humidifier to cool
before cleaning.
CARE & MAINTENANCE
Note:
• All maintenance should be done on
a water-resistant surface, such as a
kitchen counter.
• Change the water daily to avoid
bacteria growth.
• Use a tissue or cloth to clean the
nozzles regularly.
• If not using the humidifier for 1 week or
longer, do not leave water inside. Clean
and dry the humidifier instead.
Note:
• Never immerse the base in water or
liquid. Do not place any part of the
humidifier in a dishwasher.
• Do not use detergents to clean the
humidifier.
Cleaning
You should clean your humidifier every
week, and when you’re ready to store it.
1. Unplug the humidifier.

17
2. Remove and rinse the water tank cover.
3. Remove the water tank from the base,
and remove the mist channel and mist
tube. [Figure 5.1] Pour out any water from
the tank and base chamber. If you’ve
used the warm mist setting, use caution
in case the water is still hot.
Figure 5.1
Figure 5.2
Figure 5.4
Figure 5.3
Note: When pouring out water, hold
down the float to ensure that it does
not fall out of the base chamber.
4. Remove the water filter from the tank by
rotating it counterclockwise and lifting it
out. [Figure 5.2]
5. Remove the water filter sponge from
the water filter if necessary for cleaning.

8. Detach the outer water outlet valve from
the tank by rotating it counterclockwise.
[Figure 5.4]
9. Rinse all parts (except the outside of the
base) with room temperature water.
10. To descale the humidifier (remove
mineral buildup):
a. Remove the water filter and the
water outlet valve from the tank.
Remove the noise silencer and
absorption pad from the base. Keep
the mist tube and mist channel in
place.
b. Fill the tank with 3 US cups / 710 mL
of distilled white vinegar.
c. Replace the tank cover and swish
the vinegar around the tank.
d. Place the tank on the base and soak
for 15–20 minutes. Vinegar will drain
into the base chamber and loosen
scale (mineral buildup) in the tank
and in the base chamber (including
the transducer and float).
e. Remove the tank, remove the tank
cover, and pour out any vinegar.
f. Remove the float from the base
chamber by pulling up the larger
side of the float and pulling the shaft
out from the float brackets. One
side of the float brackets is open
(U-shaped) to allow the shaft to be
removed. [Figure 5.5]
g. Place the float, water filter, water
outlet valve, aroma box, and noise
silencer in a container. Fill with
enough vinegar to cover them. Soak
for 15–20 minutes.
h. Use a soft cloth and the included
cleaning brush to remove scale from
all parts. [Figure 5.6]
i. Rinse all parts until any vinegar smell
is completely gone.
