CONTROLS THAT DO THE THINKING FOR YOU
HFD280 Series
Cleaning Level Button – Once you have pressed the Power Button, use the Cleaning Level Button
to select
the desired air cleaning level. Your Air Purifier will start on the General Cleaning setting each time you turn the Air
Purifier on. Continue to press the
button to cycle through cleaning levels to reach the desired setting. Here is a
handy reference to help get the most out of your air purifier’s performance:
LEVEL 4 - MAX
Best for power cleaning the air when unpleasant odors are noticeable, your room is particularly dusty, or you
can sense that airborne particles are present. This setting provides the fastest air cleaning of all the settings
and can circulate the air frequently in the room.
LEVEL 3 - POLLEN
This setting is best for fighting airborne pollen during high pollen season, particularly in the spring and fall to
help reduce airborne pollen.
LEVEL 2 - GENERAL
Best for General Cleaning. Use this setting to help reduce airborne dust and smoke particles, like those from
cooking or tobacco smoke.
LEVEL 1 - SLEEP
Best for ultra quiet operation, perfect for nighttime use when sleeping.
Oscillate Button – To help circulate fresher, cleaner air through the room, this unit has an oscillation feature.
To turn Oscillation on, simply press the Oscillation button
once. To turn Oscillation off, press the button again.
Auto-off Timer Button – Push the
button if you would like your Air Purifier to run and then automatically
shut-off after a certain amount of time (choose from between 2, 4 and 8 hours). This is convenient if you would
like your Air Purifier to run during the night but then shut-off automatically in the morning (choose the 8 hour
setting).
