Have you moved the main unit to another room?
Are the pre-filter, pleated filter, UNIT1 and/or
humidifying filter dirty?
Are odors constantly being generated in the
room (i.e., paint, new furniture, wall paper,
sprays, cosmetics, chemicals, etc.)?
Is the UNIT1 set securely?
Are not droplets left in the opposing pole plates
or other places?
Are not bits of lint left in the UNIT1?
Was UNIT1 inadequately rinsed after cleaning

Are not the ionized wires cut?
Is the room too big?
Is indoor temperature low with the walls and
floor dry?
