HOW YOUR AIR PURIFIER WORKS
This model air purifier incorporates a 2-stage cleaning
system to help clean the air that passes through the
filter in the unit (Fig. 1).
Stage 1: Odour Reducing Pre-Filter
Stage 2: True HEPA Filter that captures
particles as small as 0.3 microns or larger
SET-UP
• Select a firm, level and flat location.
• When operating, large volumes of air are drawn toward the air purifier. Surrounding areas should be
cleaned and/or vacuumed frequently to prevent build-up of dust and other contaminates. This may
also help prolong the life of the filter. If the unit is placed on a light colored carpet, a small mat or rug
should be used underneath to prevent permanent staining. This is especially important in homes with
contamination from smoking, fireplaces, or where candles are burned.
• Ensure the front of the unit faces away from the closest wall or furniture.
• Ensure no grilles are blocked.

The True HEPA Filters and Odour Reducing Pre-Filter are supplied within the air purifier. New air purifiers
have their filters wrapped to ensure purity, and are labeled to help identify the proper replacement filter.

• Before using your new air purifier you must remove the wrappers covering the filters and Pre-Filter.
-UP
Make sure the air purifier is OFF and unplugged. Press the two hand symbols ( ) on the front grille to
release it from the unit and pull the grille toward you to remove it (see Fig. 2). Grasp the sides of the
filter frame near its top end and pull outward. Repeat for the second and third
filter if applicable.
• Remove protective wrap from the filters (including the Pre-Filter) that have
been supplied with your air purifier.
• Place the HEPA filter(s) into the air purifier housing. Ensure that the removal
"pull" tabs are facing outward (this will facilitate filter removal later). Place the
Pre-Filter on top of the HEPA filter(s). Tuck the edges of the Pre-Filter into the
tabs that are located around the edges of where the HEPA filter(s) are inserted.
This will hold the Pre-Filter securely in place.
• Replace the front grille by placing the tabs on the bottom of the grille into the
slot(s) on the unit. Gently push the top of the grille into place by pressing on the
hand symbols ( ) to secure in place.
