High efficiency air filtration and extreme versatility – all with a small footprint! The DefendAir HEPA 500 combines advanced clean air performance with the valuable features to help make the restorer’s job easier. It provides variable speed control from 250 to 500 CFM, the typical airflow level demanded on restoration job.

The DefendAir HEPA 500 uses HEPA filter media with an efficiency rating of 99.97% against 0.3-micron oily aerosol particles. When used with the optional DOP 2nd stage filter, the HEPA 500 provides assurances for first-pass filtration. The optional Activated Carbon Filter allows users to quickly and effectively attack smoke and other noxious odors in the environment.

Designed for Restoration
With user-friendly and versatile features, the HEPA 500 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 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.
