CALIBRATION
Without properly calibrated airow,
products with a True HEPA Filter will
not achieve their full ltration potential.
Gaps, poorly sealed lter housings,
and excessive air velocity all reduce the
effectiveness of the product. Independent
testing labratory veries that the precise calibration of a Vornado
Air Purier allows it to perform at True HEPA standards.

FAN SPEED
Choose one of the 4 fan speed settings, press the “+” button to
adjust to a higher speed or press the “-“ button to adjust to a lower
speed. The LED display will indicate the selected speed.
Note: Dust and allergens are most airborne when persons and pets
are active in the room. For best results, set the unit on a higher speed
setting during these times for high demand cleaning and circulation.
Set the unit to a lower setting for quieter operation when activity
is reduced.
QUICK CLEAN SPEED
A high-speed ltration setting can be used to rapidly lter the air
when airborne particle levels are high. Press the (+) on the fan speed
control until the Quick Clean icon (highlighted above) is displayed.
You will immediately notice a dramatic increase in airow that will
allow the unit to provide maximum air ltration. Due to increased
sound levels, use of this mode is recommended only as conditions
require. Low, Medium and High speed settings are designed for day-
to-day use.
POWER, Function ON and OFF by pressing the Power button.
FAN SPEED, 4 fan speed settings. Adjust between Low,
Medium, High and Quick Clean.
AUTOMATIC DUST SENSING MODE, Advanced technology
that reads the amount of particles in the air and adjusts the fan
speed accordingly. Refer to HOW TO USE to learn more about
this feature.
SLEEP MODE SETTING, Senses no light or low light conditions,
and automatically adjusts the unit to low speed. Refer to HOW
TO USE to learn more about this feature.

lter indicator light to show when it is recommended to change
the carbon lters.

Particularly ideal for darker rooms. Pressing any button will re-
illuminate the control panel.

HOW TO USE

10 English
AUTOMATIC DUST SENSING MODE
This feature monitors the air quality of the room to detect the
presence of particles, then adjusts the fan speed to improve air
quality to optimum conditions. Press the Automatic Dust Sensing
Mode Button to engage this feature. The screen will display the
animated Automatic Dust Sensing icon (shown above), to indicate
when this feature is active. The Dust Sensor will continuously
monitor the amount of airborne particles in the environment and
adjust the fan speed between Low, Medium and High as needed to
maintain optimum air quality. The Quick Clean speed is not utilized
when Automatic Dust Sensing Mode is enabled. Please note that
Automatic Dust Sensing Mode is overridden when Sleep Mode is
engaged to ensure the unit is providing a consistent, low noise level
during nighttime sleep.
WHEN TO USE:
This feature allows the unit to reduce energy usage when fewer
airborne contaminants are present in the room. Because active
people and pets tend to stir up airborne particles, the unit will tend to
increase speed during peak periods of activity in the room until lower
readings are obtained. This feature is ideal for rooms where activity
uctuates greatly based on the time of day.
Note: The Dust Sensor will need to be cleaned periodically. Please
refer to CLEANING AND MAINTENANCE.
SLEEP MODE SETTING
This feature senses no light or low light conditions, and automatically
adjusts the unit to low speed. Press the Sleep Mode button to
engage this feature. The Sleep Mode icon (shown above) will display.
Ideal for use in bedrooms. Higher and more powerful speeds may be
used throughout the day with lower speeds and minimal noise being
preferable at night.
Note: When in low light or no light, with sleep mode selected, the
unit will only operate at low speed. This will override Automatic Dust
Sensing Mode and high-speed settings. In regular light, the unit will
operate at the previous setting.
HOW TO USE

English 11
6 in.
6 in.
1. Keep retail carton to store unit when not in use.
2. Use the hand holds on either side of the unit for easy carrying.
3. For best results, position the front of the unit (side with logo)
towards the center of the room, leaving at least a 6 inch distance
away from walls or furniture on every side.
Note: For optimum airow, air outlet should be unobstructed. Ensure
curtains and other items are far enough away from the unit to not be
pulled into the side inlets or interfere with airow.
CARBON FILTER REPLACEMENT
Equipped with CARBON lter indicator light to show when it is
recommended to change the carbon lters. Please refer to FILTER
REPLACEMENT for instructions. This feature is controlled by time
of use. The light will illuminate after 4,000 hours of run time has
accumulated.
HEPA FILTER REPLACEMENT
Equipped with HEPA lter indicator light to show when it is
recommended to change the HEPA lters. Please refer to FILTER
REPLACEMENT for instructions. This feature is controlled by
time of use. The light will illuminate after 9,000 hours of run time
has accumulated.
Note: User environments will differ. The lter replacement time is
based on average use situations, if you are using the air cleaner in a
more demanding environment, you may need to change your lter
more frequently. In less polluted environments the lter life may
extend beyond the notication.

Peak performance is only realized when genuine Vornado Carbon
and HEPA lters are used. Others may claim to be compatible with
Vornado units, but the Vornado Air Purier is calibrated to achieve a
99.97% capture rate of particles 0.3 microns or larger, only when used
with Vornado Filters. 3. Remove the Plastic Support Filter Frame by pulling on the center
tabs (A). You may need to ex the Plastic Support Filter Frame
slightly to release the tabs at the top and bottom.
Note: The Front Panel is held in place by magnets, you will need to
lift the Front Panel hard enough to overcome the resistance of the
magnets.
