HOW YOUR AIR PURIFIER WORKS

This model air purifier incorporates a 3-stage cleaning
system to help clean the air that passes through the filter
in the unit (Fig. 1).
Stage 1: Washable Particle Pre-Filter
Stage 2: 99% HEPA-Type Filter with antimicrobial treatment
Stage 3: Electronic Ionizer
SET-UP
• Select a firm, level and flat location. For proper 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. 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 or fireplaces.
