INTRODUCTION
The DefendAir®HEPA 500 is a portable filtration system that draws air in from the
surrounding environment and passes it through an advanced filtration system. The
unit removes airborne particles like dust, mold spores, pollen, pet dander and miscellaneous debris.
®
HOW THE DEFENDAIR
The HEPA 500 uses an efficient mix of airflow and filtration to create “cleaner” air.
The unit’s maximum 500 CFM motor draws air into two types of filters--a pre-filter
and a HEPA filter. The first stage of filtration captures larger particles, and the second stage of filtration captures much smaller particles down to 0.3 microns.
What makes the Dri-Eaz DefendAir HEPA 500 unique is its Clean Air Delivery Rate
(CADR) capability. CADR is an Association of Home Appliance Manufacturers’
(AHAM) rating that tells you how efficiently the machine and filter work together to
remove particles from the air at the airflow rate you’re using.
You can use the DefendAir HEPA 500 for mold remediation and/or water damage
restoration. The unit is not intended for asbestos remediation.
