Note:
• The air purifier will take 5 seconds
to detect the air quality each time it
is turned on. During this time, the air
quality indicator rings will be blue. After
5 seconds, the air quality indicator
rings will change color based on the
detected air quality.
• Auto Mode does not use the Turbo

• The VeSync app also supports ECO
Auto Mode (see page 14).
Note: The percentage is approximate. The
sensor can only detect airborne particles, not
odors or gasses.
Your air purifier automatically scans your air
and analyzes the quality. By default, the air
purifier shows the overall clean air percentage
on the center of the display.
1. Tap to change the air quality
information shown on the center of the
display.
2. Keep tapping to cycle through air
quality readings for PM1.0, PM2.5, PM10,
and overall clean air percentage. For more
information, see PM Values (page 11).
3. When you stop tapping , the
current air quality reading will stay on the
display until you restart the air purifier.
If you restart the air purifier, the display
will again show the overall clean air
percentage.
Clean air percentage is an estimated
measurement of the amount of clean air in the
room, between 0% (bad) to 100% (very good).
This percentage is calculated by an algorithm,
based on:
• The concentration of particles detected in the
air, including micro-particles.
• The change in detected particles in the air
during purification.
“PM” stands for “Particulate Matter,” and usually
refers to airborne particles floating in your air,
including dust and most allergens. Many of
these particles are too small to be seen with
the naked eye, and without air purification,
they stay in the air much longer than heavier
or larger particles.
Your air purifier’s AirSight Plus 2.0 Laser
Dust Sensor detects the amount of airborne
particles that are in a given space (g/m).
Generally, the lower the number, the better
your air quality.

12
When you press to show PM
readings on the display, the number is the
estimated amount of airborne particles (g)
that are detected per 1 cubic meter (m) of air
volume.
The PM value (1.0, 2.5, or 10) refers to
particulate matter (PM) less than or equal to
1, 2.5, or 10 microns (m) in size (measured
by the diameter of the particle). For example,
PM2.5 refers to particulate matter that is 2.5
microns or smaller.
Particulate
Matter (PM) Size Examples
PM1.0 ≤ 1 m Fine dust,
micro-toxins
PM2.5 ≤ 2.5 m Dust, smoke, pet
dander
PM10 ≤ 10 m Pollen, ash, airborne
allergens
Vent Angle
Light Detection
Timer
You can set the vents on top of the air purifier
to dierent angles to disperse purified air
throughout your room more eciently.
Purified air is typically dispersed in a fixed
direction through the top of the air purifier.
Having dierent vent angles is especially
eective in rooms with a lot of furniture or
other objects that can block airflow, as well as
rooms with an unusual layout or high ceilings.
Light Detection uses the built-in light sensor to
automatically adjust air purifier settings based
on the amount of light in the room.
You can set a timer for 1–12 hours.
1. By default, the vents disperse air at a
fixed 75º angle.
2. Press to rotate the vents to a
dierent angle. The vents will cycle
through 45º, 60º, 75º, and 90º angles.
• The display will automatically turn o when
the room gets dark. If the air purifier is in
Auto Mode, it will not use the high fan speed
or Turbo Mode, even when the air quality is
poor, to avoid making too much noise.
• When the room becomes light again, the air
purifier will return to its previous settings.
The display will automatically turn back on,
and Auto Mode will no longer be limited.
1. Tap repeatedly to set a timer in 1-hour
increments, beginning with 1 hour. If you
don’t touch any buttons for 5 seconds, the
display will switch to showing the air quality
reading and the timer will start automatically.

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 17).
B. H13 True HEPA Filter
• Captures at least 99.97% of airborne
particles 0.3 microns (m) in size.
• Traps small particles such as fine
dust, smoke particles, and allergens
such as pollen and pet dander.
A B C
Note: Carbon filter eciencies decrease with use. If your air purifier isn’t as eective at filtering odors or
gasses, make sure to replace the filter (see page 19).
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.
C. High-Eciency Activated Carbon Filter
• Physically adsorbs smoke, odors, and
fumes.
• Filters compounds such as
formaldehyde, benzene, ammonia,
and hydrogen sulfide.
• Reduces household odors from food,
cigarettes, and pets.
• Tested to eectively filter volatile
organic compounds (VOCs).
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.

COVID-19 Disclaimer

16
Moisture may damage the filter. 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 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 (ACH) are calculated with 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 558 ft / 52 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 1,395 ft / 130 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
360 cubic feet per minute (CFM), or 612 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.
