Congratulations on
your new air purier
BestWater thanks you for your purchase. You have made a good choice by having
selected our product. We hope that you enjoy using the air purier for many
years to come.
Before you start operating the air purier, we request you to carefully read this
instruction manual.

Do not place the device directly under an air-conditioner so as to prevent
condensation water from dripping on the device.
Ensure that all the lters are correctly installed before you turn on the device.
Use only the original lters provided by the manufacturer for this device. Do not use
any other lters.
Ensure that hard objects do not hit against the device (especially against the air
inlets and outlets).
Always lift or move the device using the handle on the back of the device.
Do not insert your nger or objects in the air outlet.
If you have used insect repellents, do not use the device at places with oily residues
or in the presence of incense or fumes.
Do not use the device in the vicinity of gas appliances, heating appliances or
chimneys. Turn off the device after use or before cleaning.
Do not use the device in a room with major temperature uctuations because they
can lead to condensation inside the device.
The device is intended solely for use in households under normal operating
conditions.
Do not use the device in a humid environment or in an environment with high
ambient temperatures such as bathrooms, WC or in the kitchen.
The device does not remove carbon monoxide (CO) or radon (Rn). It cannot be
used as a safety device with combustion processes and hazardous chemicals in case
of accidents.
The device has a reliable protection. If the front panel has not been installed
correctly, the device cannot be started.
The manufacturer itself has equipped the device with all the lters, but the lter
packaging needs to be removed before the device can be used. Remove all the
lters, unpack them and place them again in the device, as has been described on
the following pages.

Operating the main device
Power on/off
Press the “POWER” symbol to start the device in the
manual mode at speed 2. The UV lamp and anion
generator start operating.
Press the “SPEED” symbol in any mode to switch to the
manual mode for the speed. The LCD display shows the
speeds as follows: 1- idle, 2- low speed, 3- average
speed, 4- high speed and 5- very high speed.
Press “TIMER” in any mode to circularly switch the time
between “1h-2h-4h-8h”. The LCD display shows “1h, 2h,
4h and 8h”.
Press the “MODE” symbol to circularly connect the
“Sleep-Auto/manual” mode. Actuate the respective
button to reach the manual mode. The automatic wind
speed corresponds to the signal of the air quality sensor
in the Auto mode. The better the air the lesser the wind
speed. If you press the “SPEED” symbol, you reach the
manual mode for the speed.

If you press the “ION” symbol in any mode, you can start
and stop the release of healthy anions.
If the “ “ sign on the LCD ashes after switching on
and all the HEPA square indicators do not illuminate, the
highly-efcient HEPA lter must be replaced with a new
highly-efcient HEPA lter (see chapter Installing and
replacing lters, to change the lter). Start the machine
after replacement, press and hold the RESET symbol for
5 seconds. The timer will correct itself and the
“ “ sign will stop ashing.
Caution: If the HEPA lter operates at speed 5, it has a
service life of 2000 hours.
The value of the ne dust particles in the air is indicated on
the display. This rises and falls with good and/or bad room
air.
Press the “UV” symbol in any mode to switch on or switch
off the UV lamp. The UV lamp kills effective bacteria in
the air.

Installing and replacing lters
This is how you remove the front panel
Removing the lter
Hold the top side of the front panel and pull out
in the direction of arrow 1. Remove the front
panel down in the direction of arrow 2.
Remove the highly-efcient HEPA lter,
the modied activated carbon lter and
the nano photocatalyst lter one after
the other.
Caution: While removing each lter,
hold its brackets and pull it outwards so
that the lters can be removed easily.
Installing the lter
Install the nano photocatalyst lter, the
modied activated carbon lter and the
highly-efcient HEPA lter.
Caution: Place the brackets outwards
while installing each lter. Please install
the individual lters as shown in the
gure.
Installing the front panel
The front panel must be pressed down into the
bracket in the direction of the 4th arrow and
engaged in the locking mechanism. Press the cover
gently in the direction of the 5th arrow and add the
bracket of the front panel in the AirJet 500.

Installing the UV lamp
A. Caution
Avoid eye and skin contact with the UV lamp
since it can lead to temporary and permanent
blindness. Do not look into the UV lamp directly;
this can lead to eye damage.
Do not touch the glass of the UV lamp; the
ngerprint reduces the efciency of the lamp (use
gloves).
Do not start the device without lters or with
damaged lters so as to avoid emission of
ultraviolet light from the UV lamp, which can lead
to blindness.
B. Replacing the UV lamp
The service life of the UV lamp is 8,000 hours.
This can be reached if the lamp is used for about
1 year, for 24 hours per day. Please replace the
UV lamp within this time to ensure the cleaning
capacity.
C. Installing the UV lamp
Hold the white ceramic pins at both ends of the
UV lamp(1), place the copper pin of the lamp in
the sleeve and turn it by 90° (2).
D. Installing the lter
Re-install the nano photocatalyst lter, the
modied activated carbon lter, the highly-
efcient HEPA lter and the front panel.
This is how you remove the UV lamp
Turn off the device, remove the panel, the highly-
efcient HEPA lter, the modied activated carbon
lter and the nano photocatalyst lter one after
the other. After the UV lamp has cooled down for
15 minutes, hold the white ceramic pins at both
the ends of the UV lamp and turn them by 90°
(3). Remove the UV lamp (4).
Installing and uninstalling the UV lamp

Using the remote control
Adjust the remote control within 6 m and 30
degrees to the IR receiver of the device.
Caution: The signal is week if there are
obstructions between the device and the remote
control.
It has four buttons with the same functions as
on the control panel of the device.
Maintenance and servicing
Please replace the batteries if the received
signal is weak.
Please use original batteries only.
Wrap the used batteries in plastic before
disposing them.
Keep the batteries out of reach of children. Keep the remote control dry.
Please do not pierce the remote control with a sharp object.

Highly-efcient HEPA lter: The HEPA lter collects 99.97% of the
particles (0.3 µm). It removes effective dust (inhalable particles), cigarette
smoke, bacteria, pollen, fungi, mites and radioactive particles from the air.
Modied activated carbon lter: High-quality carbon modied
using special technology, which is equally segmented into cellular holes to
remove harmful substances such as formaldehyde, VOC and other smells.
Nano photocatalyst lter: A nano photocatalyst, combined with UV light,
produces free electrons and points of oxidisation. Highly oxidising hydroxyl radicals
and superoxide ions are produced in the presence of O2 or water molecules. Hydroxyl
radicals break organic materials (e. g. formaldehyde, benzene, dimethylbenzene) and a
part of the inorganic materials into harmless carbon dioxide and water. Superoxide ions
oxidise different organic compounds, a part of the inorganic materials on the surface
is absorbed and the cell membranes of bacteria and solidied viral proteins n break.
The lter therefore has extremely effective, non-polluting and sterilising functions.
Intelligent sensor: The smart sensor automatically adjusts the motor speed to the
air quality in the room.
LCD display: Indicates the operation status of the system. The
individual modes of the system can be selected using the touchscreen.
Anion generator: More than 3 million anions generate fresh air.
Brushless DC motor: The brushless DC motor runs very softly and consumes less
power.
Ultra-exible design: The volume is 26 db at the lowest speed.
UV lamp: The UV radiation irradiates cells, viruses and other single-cell microorganisms
to destroy their DNA structure. Microorganisms cannot form any protein as a result of
which they die and cannot reproduce themselves. UV light can kill bacteria, viruses, fungi
and single-cell algae. This prevents them from spreading.
