How to Use a HEPA Air Scrubber

HEPA air scrubbers filter airborne particles — dust, mold spores, smoke and other contaminants — and can create negative air pressure for containment during remediation.

This is a general guide — always follow the specific unit's manual and contact us with any questions.

⚠ Safety essentials

  • Check the filters are properly seated before use; a bypassed filter defeats the purpose.
  • In remediation, follow containment protocols — improper setup can spread contaminants.
  • Use GFCI power and keep the unit dry.

Step by step

1

Choose air-scrubbing or negative air

Decide whether you're cleaning air within a space (recirculate) or creating negative pressure for containment (exhaust outside).

2

Position the unit

Place it centrally for air scrubbing, or at the containment boundary with ducting to the exterior for negative air.

3

Check/stage the filters

Confirm the pre-filter and HEPA filter are installed and seated. Pre-filters catch large debris and extend HEPA life.

4

Size the airflow

Match the unit's CFM to the room volume for the air changes per hour your job requires.

5

Run continuously

Operate continuously through the work, and monitor/replace filters as they load up.
