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 the build-up of dust and other contaminants. 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 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.

INSTALL TRUE HEPA FILTERS AND ODOR-REDUCING PRE-FILTER

The True HEPA Filters and Odor 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. (Type R True HEPA Filter; Type A Odor Reducing Pre-filter)

Before using your new air purifier, you must remove the wrappers covering the filters and pre-filter. 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. Model HPA300 has velcro strips on the housing where the pre-filter should be attached.
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 it in place.
