6. FAQ

Q.
The device is plugged in but the display
doesn't light up. What can I do?
A. Please check if the filter cover is closed
properly. There is a safety sensor inside the
cover that doesn't allow the device to run when
the cover is open. Please check for a possible
power failure.
Q.
The wind speed suddenly changes. Is this
normal?
A.
AUTO mode is switched on and will adjust the
wind speed according to the air quality. Please
switch to manual mode for continuous speed
operation
Q. Am I able to wash and reuse the filter?
A. HEPA filters are made out of loosely and
randomly interlaced fibers that are not built to
stand up to any stress. Washing a the filter will
destroy it in most cases. Even when the filter
seems to still be intact to the naked eye, its
structure has been rendered useless.
Q. Can I use this air purifier in a room beyond
the effective area?
In theory this purifier can clean up to approx.
A.
220m². However, this is based on a single
air change per hour (ACH). For indoor living
environments, the recommended amount of
ACH is 2-4 times.

Q. What is the effective area per ACH?
A. 1 ACH = 220m²; 2 ACH = 110m²; 3 ACH = 73m²;
4 ACH = 55m²; 5 ACH = 44m²
Why is the WIFI indicator constantly
Q.
blinking?
A.
Once the WIFI mode button is pressed, the
device will search for a mobile device to pair
with. In case pairing is failed, the indicator
will remain blinking. To switch off the blinking
indicator, press and hold the WIFI button for 3
seconds.
Q. Does this air purifier have a built-in
ionizer?
A. Yes. It releases negative ions into outgoing
filtered air. Ions are tiny particles that carry a
positive or negative charge. These ions exist
naturally around us, in the air, water and
ground. Both positive and negative ions are
colorless, odorless and harmless. Negative ions
help the air purification process by attaching
themselves to very small airborne particles in
the room.
Q. How long should I run the air purifier?
A.
In general it is recommended that you run your
air purifier when you are at home to clean the
air. The unit may be run 24/7 if preferred. This
air purifier will be more effective when windows
and doors are closed.
Q.
What does PM2.5 mean?
A. PM 2.5 is a microscopic solid particle with a
diameter of less than 2.5 micrometer. Presence
of these particles in large numbers is a serious
concern for people's health. These particles are so
tiny that they can directly invade into the lungs and
cause cancer.
Q. What does HEPA H13 stand for?
A.
HEPA is an acronym of High Efficient Particulate Air.
To qualify as true HEPA by government standards,
an air filter must remove 99.97% of all particles
greater than 0.3 micrometer from the air. H13 is
the highest classification of HEPA filters.
Q.
How long does the filter last?
A.
The lifespan of the filter depends of the air quality
and usage of the device. In practise it will last
between 4 and 6 months. The article number for
replacement filters is DXPUF03.
