you would like your air cleaner to run during the night but then shut-off automatically in the morning
(choose the 8 hour setting).
Purification Level Button – Your air cleaner will start on the General Cleaning setting each time you
turn your air cleaner on. Here is a handy reference to help get the most out of your air cleaner’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 cleans the air the fastest of all the
settings and circulates the air frequently in a room.
LEVEL 3 - ALLERGEN
This setting makes the air cleaner perform at the proper level for reducing many types of airborne
allergens. It ensures the allergen capturing efficiency and rate is best for the particle sizes being
captured. Best for fighting airborne allergens during high allergen season, particularly in the spring and
fall to help reduce airborne pollen. Also great for year-round reduction of pet dander allergens.
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.
