DefendAir HEPA 500 Air Scrubber

The DefendAir HEPA 500 is a professional-grade portable HEPA air scrubber and negative air machine designed specifically for the restoration industry — a machine built to handle the airborne contamination that water damage, mould remediation, and fire restoration generates. Using HEPA filter media with 99.97% efficiency against 0.3-micron particles, the HEPA 500 captures mould spores, bacteria, dust, smoke particles, and fine contaminants from the air as fast as high-velocity air movers generate and distribute them.

The optional Activated Carbon Filter adds a second stage that actively neutralises smoke odours, VOCs, and noxious gases — essential on fire and smoke restoration jobs where odour control is as important as particulate capture. When configured as a negative air machine — using the ducted exhaust to vent filtered air outside the containment zone — the HEPA 500 maintains negative pressure inside the remediation area, preventing contaminated air from migrating into unaffected building areas through doorways, ceiling spaces, and HVAC systems. The HEPA 500 is specifically designed to make the restorer’s job easier, faster, and more profitable — with practical features that support both air quality compliance and client confidence throughout the restoration process.
