SAFETY INFORMATION
• Only use the humidifier as described in
this manual.
• Place the humidifier and cord so that it
will not be knocked over. Do not place
near large pieces of furniture or in high-
trac areas.
• When not in use, turn the humidifier
o and disconnect from power by
removing the plug from the outlet.
• Do not use the humidifier in
wet environments.
• Keep the humidifier out of reach
from children.
• To avoid risk of electric shock, always
unplug the humidifier from the power
outlet before cleaning it or detaching
the water tank from the base.
• Always make sure the humidifier
is placed on a flat, level surface
before operation.
• 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. Only place on
water-resistant surfaces.
• Do not place foreign objects into the
humidifier’s base or water tank.
• Do not use attachments that are
not recommended by Levoit for
the humidifier.
• Do not cover the mist outlet while the
humidifier is on. Doing so may damage
the humidifier.
To reduce the risk of fire, electric shock, or other injury, follow all instructions and
safety guidelines.
General Safety
• Do not handle the power cord or plug
with wet hands. Keep the plug and
power cord away from liquids.
• Ensure that the plug fits properly into a
polarized socket.
• The 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.
Plug and Cord
• Do not allow water or other liquids
inside the air vent.
• Remove the water tank from the base
before moving the humidifier.
• Do not immerse the humidifier base,
power cord, or plug in water.
• Always allow the humidifier to
completely cool before cleaning.
• Do not use detergents to clean
the humidifier. Only use distilled
white vinegar.
• If the humidifier is damaged or is not
functioning properly, stop using it and
contact Customer Support immediately
(see 14).
• Not for commercial use. Household
use only.

GETTING STARTED
1. Remove all packaging. Choose a hard,
flat location for the humidifier at least
6 in / 15 cm away from any walls,
furniture, bedding, and appliances. The
surface must be water-resistant.
[Figure 1.1]
1. Remove the top cover from the water
tank. Fill the tank with room temperature
water. Do not fill with warm or hot water.
[Figure 1.4]
Figure 1.1
Figure 1.3
Figure 1.4Figure 1.2
Note: Do not place the humidifier on
towels, carpets, rugs, floors, or any
surfaces with fibers. This will block the air
inlet at the bottom of the humidifier and
cause overheating. [Figure 1.2]
2. Take the water tank o of the base and
remove all tape. [Figure 1.3]
Filling & Refilling
Note:
• We recommend using purified water.
• Avoid using tap water, because
the mineral content is too high and
will create white dust around the
humidifier.

6
• Do not add water directly into
the base chamber.
• Do not add water through the
mist tube.
Note: For best results, we recommend
using pure essential oil.
Figure 1.6Figure 1.5
Filling & Refilling (cont.)
CAUTION
2. Optionally, add 10–15 drops of essential
oil into the base chamber. [Figure 1.5]
3. Place the top cover back onto the water
tank. Make sure the tank is properly
placed on the base by aligning the
indicator marks. [Figure 1.6]
4. Plug in the humidifier.

• Never pour water directly into the
base chamber. Only add water to the
water tank. [Figure 2.3] The humidifier
will automatically release the correct
amount of water into the base chamber.
• Avoid moving or shaking the humidifier.
[Figure 2.4] This may cause the water
tank to release too much water into the
base chamber.
Important Tips
Note: The max water line is only for this
purpose. Do not pour water into the base.
Figure 2.3
Figure 2.5
Figure 2.4
• Before moving the humidifier, turn it o,
unplug it, and remove the water tank.
• If your humidifier doesn’t produce mist
correctly, check the max water line to
see if there is too much water in the
base chamber. [Figure 2.5] Pour out any
extra water if water is over the max line.

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 mist
outlet regularly.
• If not using the humidifier for 1 week or
longer, do not leave water inside. Dry and
store instead.
Note:
• Never immerse the base in water
or liquid. Do not place the base in a
dishwasher.
• Do not use detergents to clean the
humidifier.
