6. FAQ
The wind speed suddenly changes. Is this
normal?
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.
Am I able to wash and reuse the lter?
HEPA lters are made out of loosely and
randomly interlaced bers that are not built to
stand up to any stress. Washing a the lter will
destroy it in most cases. Even when the lter
seems to still be intact to the naked eye, its
structure has been rendered useless.
Can I use this air purier in a room beyond
the eective area?
In theory this purier can clean up to approx.
27m². 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.
What is the eective area per ACH?
1 ACH = 80m²; 2 ACH = 40m²; 3 ACH = 27m²; 4
ACH = 20m²; 5 ACH = 16m²

Does this air purier have a built-in
ionizer?
Yes. It releases negative ions into outgoing
ltered 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 purication process by attaching
themselves to very small airborne particles in
the room.
When should I turn on the air purier?
In general it is recommended that you run your
air purier when you are at home to clean the
air. The unit may be run 24/7 if preferred. This
air purier will be more eective when windows
and doors are closed.
What does PM2.5 mean?
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 health problems.

What does HEPA H13 stand for?
HEPA is an acronym of High Ecient
Particulate Air. To qualify as true HEPA by
government standards, an air lter must
remove 99.97% of all particles greater than
0.3 micrometer from the air. H13 is the
highest classication of HEPA lters.
How long does the lter last?
The lifespan of the lter 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 lters is DXPUF06.
Disposal
The European directive 2012 / 19 / CE on Waste
Electrical and Electronic Equipment (WEEE),
requires that old household electrical appliances
must not be disposed in the normal unsorted
municipal waste stream. Old appliances must
be collected separately in order to optimize the
recovery and recycling of the materials they
contain and reduce the impact on human health
and the environment. The crossed out “wheeled
bin” symbol on the product reminds you of your
obligation, that when you dispose of the appliance
it must be separately collected. Consumers
should contact their local authority or retailer for
information concerning the correct disposal of
their old appliance.
