About the Filters
A. Fine Preliminary Filter (Pre-Filter)
•Captures large particles such as
dust, lint, fibers, hair, and pet fur.
•Maximizes the life of the True
HEPA Filter by protecting it.
B. True HEPA Filter (H13 HEPA Class)
•Removes at least 99.97% of
airborne particles as small as 0.3
micrometers (µm) in diameter.
•Traps fine partiles such as dust
mites,pet dander,mold spores
and pollen.
Note：Levoit air purifiers reduce
airborne particles 0.3 microns or
larger and make no claims to
help reduce COVID-19 viruses.
C. Activated Carbon Filter
•Physically adsorbs smoke, odors,
and fumes.
Your Levoit Desktop True HEPA Air Purifier
uses 2 filters, both of which use a 3-stage
air filtration system to purify air.
G E TTING S TA R TED
1. Flip over the air purifier. Twist the cover
of the air purifier. [Figure 1.1]
2. Take out the filters and remove the

USING YOUR AIR
PURIFIER
1. Press the Control Button to turn on the
air purifier. The fan will start on “SLEEP”.
2. Optionally, press the Control Button
repeatedly to change fan speed
(“SLEEP”, “LOW”, and “HIGH”), and to
turn the air purifier o.
WARNING: Make sure the air outlet and the
air inlets are not blocked. This may cause
the air purifier to overheat and stop working.
Note:
• Sleep Mode uses the lowest
possible fan speed for a quiet
environment.
• In Sleep Mode, the display lights
will automatically turn o after 5
seconds. Press the Control Button
again to turn the display lights back
on for 5 seconds.
Note:
• “HIGH” is the loudest fan speed, but
cleans air the quickest.
• For best results, or to address
a specific air quality issue such
as smoke, run the air purifier on
“HIGH” for 15–20 minutes before
using a lower speed.
• To eectively clean air, keep
windows and doors closed while
the air purifier is on.

Air Purifier Placement
Clean Air Delivery Rate
Adding Essential Oils
Humidity
For highest eciency of air purification,
make sure that airflow isn’t obstructed. To
allow air to circulate freely in and out of the
air purifier, there should ideally be
15 in / 38 cm of clearance on all sides of
the air purifier. Avoid placing too near a
corner or too close to a wall. Keep away
from curtains and anything that might block
airflow.
This air purifier has a Clean Air Delivery
Rate of 70 cubic meters per hour.
Clean Air Delivery Rate (CADR) measures
the eciency of an air purifier by indicating
the volume of clean air that an air purifier
produces. This is based on the removal
of dust, pollen, and smoke, which are the
3 most common indoor air pollutants. The
higher the CADR, the more particles the air
purifier will remove and the larger the area it
can clean. The rating is measured at the air
purifier’s highest speed.
Moisture may damage the filters. This air
purifier should be used in an area with a
humidity level below 85% RH. If you use the
air purifier in excessively humid areas, the
surface of the filters will become moldy.
Note: Water or moisture will allow mold
to grow. To solve a mold problem, get
rid of the source of the moisture and
clean up the mold. Air purifiers cannot
solve an existing mold problem, only
remove airborne mold spores and
reduce odors.
Note: Do not mix essential oil blends.
Clean the aroma pad before using a
new essential oil blend (see Cleaning
the Aroma Pad, page 9).
Note: Essential oils are not included.
Essential Oils
Do not add essential oils to the filters or the
fan. The filters will be damaged by the oil
and will eventually release an unpleasant
smell. Only add essential oils to the aroma
box at the top of the air purifier.
USING YOUR AIR PURIFIER (CONT.)
1. Remove the aroma box cap.
2. Add 2–3 drops of the essential oil to the
aroma pad.
3. Replace the cap.

CARE & MAINTENANCE
Cleaning the Air Purifier
Note:
• For best performance, clean every
1–2 months.
• WARNING: Do not disassemble the
air purifier, such as by removing any
screws. Only remove the filter cover
and replace filters as directed.
• Do not clean with detergents or
soap, as this may cause damage
or discolouration. Do not clean with
abrasive chemicals or flammable
cleaning agents.
1. Unplug before cleaning.
2. Wipe the outside of the air purifier with
a soft, dry cloth. If necessary, also wipe
with a damp cloth, then immediately dry.
3. Vacuum the inside of the air purifier
using a vacuum hose with a crevice
attachment. [Figure 2.1]
Cleaning the Filters
The Pre-Filters should be cleaned about
once a month to increase the eciency
and extend the life of your filters. Clean
the outside of the Pre-Filter using a soft
brush or a vacuum hose with a soft brush
attachment to remove hair, dust, and large
particles. Do not clean any part of the filters
with water or other liquids.

When Should I Replace the
Filters?
You should replace your filters every 6–8
months. You may need to change your
filters sooner or later depending on how

change the filters more often, even if the
red indicator light is o.
You may need to replace your filters if you
notice:
• Increased noise when the air purifier
is on
• Decreased airflow
• Unusual odors
• Visibly clogged filters
