Where to place the air purifier
1. Place your air purifier across the room from an air conditioner or heating
vent. If there are no vents in the room, place the air purifier near a return
air inlet.
2. Do not place furniture or large objects directly in front of the air purifier.
3. Place the air purifier at least 8 inches (20 cm) away from the wall.
4. In a bedroom, place the air purifier three to four feet (1.2 m) from the bed
side.
5. Placing the air purifier near an open window may reduce its efficiency.
Polarized plug
To reduce the risk of electric shock,
this appliance has a polarized plug
(one blade is wider than the other).
This plug will fit in a polarized outlet
only one way. If the plug does not fit
fully in the outlet, reverse the plug. If
it still does not fit, contact a qualified
electrician to install the proper outlet.
Do not change the plug in any way.

When to replace
The collection sheet should be

the room are high, the sheet may
need to be changed more frequently.
Please note that the collection sheet
change light is automatically reset to
a new 30-day period each time the
front cover is removed, even if the
collection sheet is not replaced. Dur-
ing normal operation, it is generally
not necessary to remove the front

sheet. The collection sheet should be
changed at least once each month,
more often if particle or smoke levels
are high.
