Getting started

Press the Start/Stop button to start the operation.

Adjusting the Fan Speed

Press the Speed button during operation to adjust the air flow.

• Continuously pressing the button repeats the operation modes
in the sequences of Auto → Low (L) → High (H) → Turbo →
Auto, and so on.

NOTE

• The speed is set to Auto when you first start the operation.
Auto mode controls the fan speed automatically according to
the contamination level of the indoor air.

• When you start the operation again after stopping it, the
operation will begin with the last selected speed.

• You can check the speed from the status display panel.

• When the operation begins, the light of air quality turns white
during the particles sensor stabilization time (30 seconds).
When stabilization of the particles sensor is completed, the
light of air quality indicates air quality.

Using the Turbo Mode

The product operates powerfully for 30 minutes to purify
indoor air promptly.

• You can use the Turbo mode by pressing the Speed button
during operation. All lights of Speed turn on when the product
is operating in the Turbo mode.

• You can use the Turbo mode by pressing the Turbo button on
the main screen of the Puricare Mini app.

• When you operate the product in Turbo mode, the product
operates for 30 minutes and then returns to the previous
mode.

Checking the Air Quality

You can check the air quality through the light of air quality.
The light of air quality indicates the level of air quality in 4
colours, green, yellow, orange and red, based on concentration
of the particles.

The concentration of the particles can be checked using the
Puricare Mini app.

NOTE

• If the concentration of the particles is kept high even after
changing the operation environment, visit your customer
service centre to clean the particles sensor.

Using the air quality monitoring function

You can execute the Puricare Mini app and set the time to turn
on the particles sensor through the product management menu.

- Turns On with Product

- Always On: Monitor the air quality even when product
operation is suspended

NOTE

• The concentration of particles could be affected by cooking or
using humidifiers, sprays or other products which generate
steam or fine particles.

• Even two products placed in the same space could measure
the concentration of particles differently due to air circulation.

• The concentration of the particles displayed may change with
environmental factors such as the presence of sofas, beds,
carpets, vacuum cleaners, humidity, smoke, bugs, pets or
cooking oils.

• The PM concentration may be affected by changes in the
outside environment such as construction, heavy traffic or
pollen.

• The concentration of the particles could be higher near outside
doors, windows, vents or in areas where outside air enters. Air
flow near the particles sensor may interrupt normal operation
of the particles sensor and indicated concentration may be
different from actual particles concentration, accordingly.

• Be careful as the battery may be discharged rapidly when the
air quality monitoring function is used.

• PM (particulate matter) concentration is displayed in
increments of 1 unit, from 8 to 999. PM concentration values
are based on the data sheet provided by the sensor
manufacturer.

• The PM concentration measurement was tested using LG
Electronics’ standard test materials.
