HOW YOUR AIR PURIFIER WORKS
The Honeywell Professional Series™ True HEPA Air Purifier
uses a powerful 4 Step Cleaning System to help purify the
air that passes through the filters in the unit (Fig. 1).
Step 1:
Washable/Vacuumable Mesh Pre-Filters
at Air Intake – these filters help to capture
larger airborne particles such as pet hair/
fur and dust before they reach the HEPA
Filter. These filters should be removed
approximately every 3 months and washed
or vacuumed clean.
Step 2:
HEPA Filters capture up to 99.97% of airborne particles as small as 0.1 micron

Step 3:
Antimicrobial coating inhibits growth of bacteria on filters

Step 4:
Granulated Activated Carbon Filter traps odors and VOCs.
GETTING STARTED
• 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 contaminants. This may also help
prolong the life of the filters. 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.
