including those listed below. As the app
develops, more features may become
available.
Remote Control
• Change any air purifier settings
through the app, even while Display
Lock is on.
Pet Mode
• Pet Mode is ecient at filtering
allergens from the air while
conserving energy.
• When Pet Mode is on, the air purifier
runs for 15 minutes at high speed
(3 indicator lights), then 60 minutes
at medium speed (2 indicators),
and cycles between the two fan
speeds. The corresponding fan
speed indicators and on the air
purifier’s display will light up.
• When Pet Mode is on, and the light
sensor detects the room is dark, the
display will turn o and limit Pet Mode
to medium fan speed (2 indicators), to
avoid making too much noise. When
the light sensor detects that the room
is lit again, Pet Mode will no longer
be limited, and the air purifier will run
at medium fan speed (2 indicators)
for 30 minutes, then run at high (3
indicators) for 15 minutes. After this,

Auto Mode
Access additional auto modes: Quiet Auto
Mode and Ecient Auto Mode.
• Quiet Auto Mode uses the medium
fan speed (2 indicator lights) instead
of the high or turbo fan speeds, even
when the air quality is poor, to avoid
making too much noise.
• Ecient Auto Mode lets you choose
the size of the area you want to
purify. The air purifier will use the
turbo fan speed to clean the air for a
designated amount of time. This time
is based on 1 ACH and the size of
the room, meaning how long it takes
for the air purifier to clean all the air
in your room one time, regardless of
the air quality. After this, the mode
will adjust the fan speed according
to the actual detected air quality in
the room.
Note: Ecient Auto Mode is useful for purifying
odors from the air. The air purifier’s dust sensor
can only detect particles in the air, not smells.
Ecient Auto Mode does not rely on the dust
sensor, but the room size instead.

ABOUT THE FILTER
The air purifier uses a 3-stage filtration system to purify air.
A. Washable Pre-Filter
• Captures large particles such as dust,
lint, fibers, hair, and pet fur.
• Maximizes the filter’s life by
protecting it.
• Removable and washable to increase
filtering eciency (see Cleaning the
Pre-Filter, page 18).
B. H13 True HEPA Filter
• HEPASmart™ Technology uses
statically charged fibers to capture
viruses and bacteria with greater
eciency.
• Traps at least 99.97% of airborne
particles 0.3 microns in size.
• Filters small particles such as fine
dust, smoke particles, and allergens
such as pollen and pet dander.
C. High-Eciency Activated Carbon Filter
• Physically adsorbs smoke, odors, and
fumes.
• Filters compounds such as
formaldehyde, benzene, ammonia,
hydrogen sulfide, and volatile organic
compounds (VOCs).

Note: Levoit has not tested its air purifiers
for eectiveness against SARS-CoV-2 and
makes no claims that these air purifiers help
reduce the spread of COVID-19.
According to the CDC, portable HEPA
filtration units that combine a HEPA filter
with a powered fan system are eective
at cleaning air within spaces to reduce
the concentration of airborne particulates,
including SARS-CoV-2 (COVID-19) viral
particles.

Moisture may damage the filter. This air
purifier should be used in an area with a
humidity level 85% RH or below. If you use
the air purifier in excessively humid areas, the
surface of the filter may become moldy.
Do not add essential oils to the air purifier or
filter. The filter will become damaged by the
oil and will eventually release an unpleasant
smell. Do not use diusers near the air
purifier.
The air change rate is how many times all of
the air in a room can be purified (or “changed”)
by the air purifier in 1 hour. Air changes per
hour are calculated on the recommended
room size assuming 8 ft / 2.4 m ceilings. For
smaller rooms, the air change per hour will
increase. This air purifier can change air 5
times per hour at the max speed in a single,
closed room up to 219 ft / 20 m. This is
measured at ACH 5. The air purifier is eective
for larger rooms, but air purification will take
longer, with fewer air changes per hour. For
example, the air purifier’s eective range is
548 ft / 50 m based on 2 ACH, or purifying
the air in the room 2 times per hour.
This air purifier has a Clean Air Delivery Rate of
141 cubic feet per minute (CFM), or 240 m/h.
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
per minute. This is based on 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.

CARE & MAINTENANCE (CONT.)
The Washable Pre-Filter should be cleaned
every 2–4 weeks to increase eciency and
extend the life of your filter. You can set a
reminder in the VeSync app to clean the
pre-filter every 2, 3, or 4 weeks. Clean the
pre-filter using a soft brush or vacuum hose
to remove hair, dust, and large particles.
Optionally, you can wash the pre-filter with
water and a mild detergent to remove dirt
and dust.
Note: Avoid scrubbing, scraping, or
vigorously brushing the pre-filter. Do not
use abrasive cleaning materials.
To wash the pre-filter:
1. Turn o the air purifier.
2. Open the front cover
3. Push the pre-filter’s tabs inward and pull
to remove the pre-filter.
4. Clean the surface of the pre-filter with a
vacuum. [Figure 2.1]

Replacing the Filter
CARE & MAINTENANCE (CONT.)
The True HEPA / Activated Carbon Filter
should be replaced every 9 months. You
may need to replace your filter earlier or
later depending on how often you use
your air purifier. Using your air purifier in an
environment with relatively high pollution may
mean you will need to replace the filter more
often, even if the Check Filter Indicator is o.
You may need to replace your filter if you
notice:
• The air purifier does not eectively filter
certain odors anymore
• Increased noise when the air purifier is on
• Decreased airflow from the top of the air
purifier
• Unusual odors
• The HEPA filter is visibly dusty or
discolored after removing the pre-filter
When Should I Replace the
Filter?
Note:
• To maintain the performance of your air
purifier, only use ocial Levoit filters.
For more information, contact Customer
Support (see page 26).
• Remember to reset the Check Filter
Indicator after replacing the filter (see
page 17).
1. Unplug the air purifier, then pull the front
cover to remove it (see Getting Started,
page 7).
2. Push the pre-filter’s tabs inward and pull to

Cleaning the Dust Sensor
If not using the air purifier for an extended
period of time, wrap both the air purifier and
the filter in plastic packaging and store in a
dry place to avoid moisture damage.
Storage
It is recommended to clean the AirSight™
Infrared Dust Sensor lens every 2 months
to help maintain the eciency of the sensor.
If the Air Quality Indicator is red (indicating
“Bad” air quality) more than usual, you may
need to clean your dust sensor.
Note: How often you clean the dust sensor
will depend on the air quality of your
environment. If your air is often polluted with
dust, dander, smoke, and other particles,
you may need to clean your dust sensor
more often.
Note: Do not remove the foam piece
attached to the dust sensor cover
unless instructed by Customer Support.
