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.

USING YOUR 2IN1 HUMIDIFIER & DIFFUSER
Note:
• If there is no water in the tank, the
humidifier will not turn on and will
blink. Fill the water tank (see Getting
Started, 5).
• Keep the humidifier stable while using, or
water may spill.
• Do not block the mist outlet. This will
damage the humidifier. [Figure 2.1]
1. Press once. The humidifier will start
on the low mist level. [Figure 2.2]
2. Press repeatedly to cycle through
mist levels (low, medium, high) and to
turn the humidifier o. [Figure 2.2]
Mist Level
Intelligent Sleep Mode turns o all display
lights and uses a humidity sensor to
automatically adjust the mist level to
maintain a 60% relative humidity (RH) while
you sleep.
1. Press to turn on the humidifier.
Intelligent Sleep Mode
Note: The humidifier must be on to start
Sleep Mode.
2. Press to start Sleep Mode. After 5
seconds, all display lights will turn o.
3. Press a second time (or press )
to cancel Sleep Mode. The humidifier
will go back to the previously set mist
level.

• 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.
Cleaning
Clean your humidifier every week, and
when you’re ready to store it.
1. Unplug the humidifier. [Figure 3.1]
2. Remove and wash the top cover.
[Figure 3.2]
3. Remove the water tank from the base.
Pour out all water from the tank and

Problem Possible Solution
Humidifier doesn’t turn
on, or the buttons do
not work.
Unplug the humidifier and plug it back in. Press to turn the
humidifier on.
Fill the water tank if it is empty.
Little or no mist comes
out.
Press to use a higher mist setting.
Make sure the mist tube is correctly installed (see Installing the
Mist Tube, 10).
Make sure the water level in the base is not too high.
Water may be dirty, and there may be mineral buildup inside
the base. Clean the transducer with a cleaning brush and white
vinegar and make sure all parts are properly installed (see Care
& Maintenance, 9). Fill with clean water.
Make sure the mist outlet and air inlet are not blocked (see
Getting to Know Your 2-in-1 Humidifier & Diuser, 4).
Humidifier is hot (or the
water inside is hot), and
little or no mist comes
out.
Make sure the air inlet at the bottom of the humidifier and the
mist outlet at the top of the humidifier are not blocked. Do not
place the humidifier on floors, carpets, rugs, or surfaces with
fibers that may block the air inlet.
Make sure the mist tube is correctly installed (see Installing the
Mist Tube, 10). If the mist tube is not in place, the humidifier
will not create mist, and the water temperature will rise. This is
not dangerous, but the humidifier will not work correctly until the
mist tube is put in place.
Humidifier uses water
too quickly.
The humidifier uses up water based on the environmental
temperature and humidity. If your environment is cold and/or dry,
the humidifier will run out of water faster.
TROUBLESHOOTING
Storing
Follow the cleaning instructions (see 9) and allow all parts to dry completely before storing.
Store in a cool, dry location.

If your problem is not listed, please contact Customer Support (see 14).
TROUBLESHOOTING (CONT.)
Problem Possible Solution
Humidifier produces an
unusual smell.
If the humidifier is new, remove the top cover, and place the
water tank in a cool, dry place for 12 hours.
Water may be dirty or has been sitting in the tank for a long
period of time. Clean the humidifier (see Care & Maintenance,
9) and refill with clean water.
If essential oils were diused, clean with white vinegar (see Care
& Maintenance, 9), and allow the humidifier to dry.
White dust appears
around the humidifier.
This is caused by using water with high mineral content. Use
purified water to fill the humidifier.
Clean the humidifier (see Care & Maintenance, 9).
Water leaks from
the humidifier.
Make sure the tank is properly placed on the base by aligning
the indicator marks (see 5).
Make sure the sealing ring inside the water tank is securely in
place. If necessary, clean the sealing ring and make sure it can
open and close normally.
Make sure the mist tube is correctly installed and securely in place
(see 10).
Make sure the float is correctly installed and securely in place.
When humidity is too high, water may condense on the surface of
the humidifier or surrounding area. Turn down the mist level or turn
o the humidifier.
Water outlet may be blocked by mineral buildup. Clean the water
outlet valve assembly with vinegar.
Essential oils have little
or no smell.
Make sure you’ve added 10–15 drops of oil into the base chamber.
For best results, we recommend using pure essential oil.
