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

Plug and Cord
• Do not handle the power cord or plug

• 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.

GETTING STARTED
1. Place the humidifier on a level, elevated,
and water-resistant surface, such as a
table or nightstand.
Note: Keep mist away from walls, furniture,
and appliances to prevent them from
getting wet.
2. Take the water tank o of the base and
remove all tape.
3. Remove the top cover from the

2 cups / 475 mL of cold or room
temperature filtered water.

• Only use filtered water in the
humidifier.
• Do not use hot water.
• Do not fill above the “MAX” line.
[Figure 1.1] Overfilling can cause
spilling and risk of electric shock.
• Do not add water through the mist
tube. This will damage the humidifier.
• When pouring water, never let water
get inside the air outlet (see Getting
to Know Your 2-in-1 Humidifier &
Diuser, page 5).
• If water gets inside the air outlet,
unplug the humidifier and pour out all
water. Let the humidifier rest in a wellventilated area for 24 hours. Do not
use again until completely dry.
4. Optionally, add 4–6 drops of essential
oil into the water tank.
Note: Only add essential oils into the
