What is a HEPA air scrubber?
A HEPA air scrubber is a portable or stationary air filtration device that removes airborne mold spores, dust, and particulates using a true HEPA filter meeting the 99.97% filtration standard at 0.3 microns.
During water damage remediation work, disturbed materials release mold spores and fine particulates into the air. A HEPA air scrubber captures these contaminants to prevent them from settling elsewhere in a building and to protect workers and occupants from inhalation exposure.
The device operates by drawing air through a series of filters. A true HEPA filter must meet a strict standard: it removes at least 99.97 percent of airborne particles 0.3 microns or larger. Pre-filters and carbon filters often precede the HEPA stage to extend filter life and remove odors.
HEPA air scrubbers are standard equipment during mold remediation and water damage recovery. They run continuously while containment areas are active and during the demolition and drying phases. Portable units are placed within or adjacent to work zones, while larger truck-mounted or trailer-mounted systems may serve multiple areas. The filtration standard ensures that particles small enough to remain suspended in air (including most mold spores) are captured rather than recirculated.
Restoration professionals in Ontario rely on HEPA air scrubbers to meet industry protocols and regulatory expectations for safe remediation. When selecting a restoration contractor, confirm that their mold remediation work includes certified HEPA equipment operated throughout the project.
