• Do not use where combustible
gases or vapors, metallic dust,
aerosol (spray) products, or fumes
from industrial oil are present.

• Supervise children when they are
near the air purifier.
• Do not place anything into any
opening on the air purifier.
• Do not sit or place heavy objects
on the air purifier.
• Keep the inside of the air purifier
dry. To prevent moisture buildup,
avoid placing in rooms with major
temperature changes.
• Always unplug your air purifier
before servicing (for example,
changing the filter).
• Do not use your air purifier if it is
damaged or not working correctly,
or if the cord or plug is damaged.
To reduce the risk of fire, electric shock, or other injury, follow all instructions and
safety guidelines.
General Safety
• Keep the air purifier near the outlet

• Never place the cord near any heat
source.
• Do not cover the cord with a rug,
carpet, or other covering. Do not
place the cord under furniture or
appliances.
• Keep the cord out of areas where
people walk often. Place the cord
where it will not be tripped over.
• Your air purifier has a polarized
plug (one prong is wider than the

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.

USING YOUR AIR PURIFIER (CONT.)
The air purifier will remember its
programmed settings when turned o,
and will resume these settings when it is
turned back on. The air purifier must remain
plugged in for the memory function to work.
Memory Function
The PM2.5 value on the display shows the
amount of particles (µg) that are detected
within 1 cubic meter (m³).
PM2.5 refers to particulate matter (PM) that
is less than or equal to 2.5 micrometers
(µm) in diameter. These particles, also
known as “fine particles”, are so small that
they can only be detected with an electron
microscope, and stay in the air longer than
heavier air particles such as dust and mold.
Your air purifier is equipped with a laser dust
sensor that detects the amount of PM2.5
particles that are in a given space (µg/m³).
Generally, the lower the number, the better
your air quality. A number above 135 indicates
that there is an unhealthy amount of fine
particles in the air.
You can set a timer between 1– 12 hours.
1. Tap repeatedly (or press and
hold ) to set a time.
2. Once you choose a time, the timer will
flash 5 times and start counting down.
3. The air purifier will automatically turn o
once the timer is finished.
4. To cancel a timer, tap repeatedly
until the timer reads “- - - -”. The timer
will flash 5 times to confirm cancellation.

Note:
• You can change the fan speed at
any time while the timer is counting
down. The timer will work with any
mode.
• Pressing or unplugging the air
purifier will cancel the timer.
Note: The air purifier will not
remember timers.

ABOUT THE FILTER
The True HEPA Combination Filter uses a 3-stage filtration system to purify air.
A. Nylon 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. H13 True HEPA Filter
• Removes at least 99.97%
of airborne particles 0.3
micrometers (µm) in diameter.
• 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 air purifiers filter airborne
particles 0.3 microns in size. Arovast
Corporation makes no claims that this air
purifier helps reduce the COVID-19 virus.

Storage
If not using the air purifier for an extended
period of time, wrap the filter in plastic

When Should I Replace the
Filter?
The filter should be replaced every 6–8
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 change the filter
more often (even if the is o).
You may need to replace your filter if you
notice:
• Increased noise when the air
purifier is on
• Decreased airflow
• Unusual odors
• A visibly clogged filter
