Product Information

The Dri-Eaz HEPA 500 Air Scrubber and Negative Air Machine is Stackable, Lightweight, and Easily Transportable!


Get everything you need to do the job right: high-efficiency air filtration, the maximum clean air rating from the Association of Home Appliance Manufacturers  (AHAM), and extreme versatility—all with a small footprint!


The Dri-Eaz DefendAir HEPA 500 Air Scrubber combines advanced clean air performance with the ultimate assortment of features to help make the job of a restoration pro a cinch.


Built-in Microban® antimicrobial product protection inhibits the growth of bacteria, mold, and mildew—the culprits that cause stains, odors, and product deterioration.


The DefendAir HEPA 500 Air Scrubber uses HEPA filter media with an efficiency rating of 99.97% against 0.3-micron oily aerosol particles and provides 250 to 500 CFM, the typical airflow level demanded on restoration jobs.


This unit also offers flexible ducting options, so it can be used as a negative air machine. This is a great feature when working in contaminated or highly sensitive environments.

Designed for Restoration
With user-friendly and versatile features, the HEPA 500 Air Scrubber is ideal for handling indoor air quality needs on every restoration job. Any job that involves sewage, mold, or fire damage clearly involves significant amounts of particulates and smelly gasses—a direct result of the damage itself. In a water damage restoration environment, the high-velocity airflow needed for drying can stir up particulates that have settled in carpet or on other materials.


The HEPA 500 Air Scrubber / Negative Air Machine can address indoor air quality quickly and efficiently and help restore any environment to a pre-loss condition—the ultimate goal of every restoration job.
