• Select a firm, level and flat location. For best airflow, locate the unit at least 3 feet (1 M) from any wall
or furniture.
• 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. 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 exit grille (front of the unit) faces away from the closest wall or furniture.
• Ensure no grilles are blocked.
The HEPA-Type Filters are supplied within the air purifier. They are wrapped to ensure purity.

pulling the grille towards you (Fig. 2).

• Place the filters back into the air purifier housing and snap the rear grille back
into place.
NOTE: The pre-filter needs to be in position along the rear grille before
snapping the grille back into place.
NOTE: The Top filter must be securely in place in order for the unit to operate.
