• Never immerse the appliance in water or any other liquid.
• Never use aggressive or flammable cleaning agents such as bleach or alcohol to clean any
part of the appliance.
BODY OF THE APPLIANCE
Regularly clean the inside and outside of the body to prevent dust from collecting.
• Wipe away dust with a soft dry cloth from the body of the appliance.

PRE-FILTER SCREEN
The pre-filter/charcoal layer collects larger dust and debris and should be cleaned monthly or
more frequently depending on use. Remove and clean regularly with the brush attachment of
your vacuum cleaner. This will remove the lint and dirt and help maintain the life of the filter.

Caution: Do NOT use gasoline, benzene, thinner, harsh cleaners, etc. on and/or in the
unit while cleaning as they will damage the products.

TROUBLESHOOTING GUIDE

PROBLEM

or does not operate.
No air circulating from the unit. Unplug unit. Check filter. Clean or replace filter if necessary.
Odors not removed.
Discharged air has an odor.

What is CADR?
CADR stands for "Clean Air Delivery Rate," which indicates the volume of filtered air delivered by
an air purifier. CADR ratings show the effectiveness of how efficient the air purifier is at capturing
fine particles from things like tobacco smoke and plant pollens from the room.
Clean Air Delivery Rate
From air cleaner to air cleaner, compare the CADR numbers. First look at suggested room size. Then refer
to the Clean Air Delivery Rate (CADR) numbers. The higher the number, the faster the unit filters the air.
Refer to website for individual model CADR numbers.
