If in MANUAL mode, please check the fan speed
slider on the product UI or within Wellbeing App and
adjust it to desired level.
If in SMART mode, please check air quality indicator
on the product UI or within Wellbeing App – if all PM
values are constantly reading very good without any
increase then this is normal behavior for the unit -
your air quality is very good! If the PM2.5 value is
high and the unit is still operating at lowest fan
speed, then please check filter change icon on the
product UI or within Wellbeing App and if lit please
replace used filter with a new one, this should resolve
the specific fan speed issue.
If neither of the above steps OR instructions in the
Wellbeing App help, please refer to item 9 in the
table.
Please ensure the air inlet (around front panel) and
air outlet grill (top of the unit) are unobstructed and
that there is a clearance of at least 30 cm between
these areas and the nearest surface. If using a custom
fabric cover, try to reapply the fabric cover to the
panel tighter OR try operating without it to see if
noise pattern becomes normal.
If neither of the above steps OR instructions in the
Wellbeing App help, please refer to item 9 in the
table.
Ensure that the house, wall socket being used, and
not the unit are all receiving power. If needed, try
pushing the power plug firmly into the wall socket to
check if this resolves the issue.
If you have recently (re)placed a filter please remove
and reinsert it. Check to make sure that the filter is
oriented correctly, so the RFID sensor can detect it.
If neither of the above steps OR instructions in the
Wellbeing App help, please refer to item 9 in the
table.
The unit is designed
so that when a filter
is at end of life, at
least within the
SMART mode, it will
discourage usage till
the filter is replaced,
by limiting the fan
speed so as not to
reintroduce the
captured particulate
matter back into the
air.
An abnormal pattern
of noise OR an
unusually high pitch
is not by design,
hence it is best to
rectify this.
As a safety
mechanism, to avoid
risk of injury from
the fan blade, the
unit will not operate
if it does not detect
the presence of
filter(s).
