Problem
Possible solution
The color of the air
quality light always
stays the same.
•
The air quality sensor is dirty. Clean the air quality sensor
(see chapter "Cleaning").
The air purifier
produces a
unpleasant smell.
•
The first few times you use the air purifier, it may produce
a plastic smell. This is normal. The air purifier may also
produce an unpleasant smell when the filter is dirty. In this
case, clean or replace the appropriate filter.
•
If the air purifier produces a burnt odor, switch OFF and
unplug from the electrical outlet. Call 1-866-309-8817 for
assistance.
The air purifier is
loud.
•
If the air purifier is too loud, change the fan speed to a
lower fan speed level. When using the air purifier in a
bedroom at night, choose the sleep mode.
The air purifier still
indicates that I
need to replace a
filter, but I already
did.
•
Perhaps you did not reset the filter lifetime counter. Plug
in the air purifier, touch to switch on the air purifier, and
touch and hold the reset button
for 3 seconds (see
Filter force reset section).
Error codes "E1",
"E2", "E3" or "E4"
displays on the
screen.
