3.2.1 Regulating Fan Speed
Your IQAir cleaner can be set to run at five fan speeds which correspond to five different air flow
rates. Speed 1 is the lowest, speed 5 the highest fan speed.The higher the air flow, the more room
air will be filtered by the unit.The high fan speed settings provide you with the additional air cleaning
power to deal with situations of elevated air pollution levels.
To allow better evaluation of the performance of your air cleaner at different fan speeds, the
standard display window shows in addition to the fan speed also the air delivery rate (air flow).
The displayed air flow is factory preset and is not measured by the air cleaner itself.
