HEPA Air Scrubbers for Restoration & Remediation
Air filtration systems from Grimeworks capture airborne dust, mold spores, allergens, and other contaminants during construction, renovation, water damage restoration, and abatement projects — protecting both your crew and building occupants from airborne particles that standard cleaning equipment simply isn't built to handle.
Our entire lineup runs on Aerospace America's AeroClean platform, giving you a genuinely deep range of CFM capacities, from compact remote filter units up to industrial-grade turbo and pneumatic models built for the toughest hazardous environments.
Air Scrubber vs. Negative Air Machine: Know the Difference
These terms are often used interchangeably, but they describe two different operating modes:
Air Scrubber Mode — The unit recirculates filtered air back into the same room, cleaning the air within an occupied or contained space without exhausting it elsewhere.
Negative Air Machine Mode — The unit exhausts filtered air outside the containment area, creating negative pressure that actively prevents contaminants from escaping into adjacent spaces. This is the standard approach for mold remediation, asbestos abatement, and other regulated containment work.
Many units, including several in our AeroClean lineup, can run in either mode depending on how they're ducted — worth confirming for your specific project requirements.
Sizing Your Air Filtration System: CFM and ACH
The key sizing calculation for any air filtration system is Air Changes per Hour (ACH) — how many times the unit fully filters the air volume of your containment space in an hour. To estimate the CFM you need:
- Calculate your containment's cubic footage (length x width x height).
- Divide by 10 for a rough estimate of the CFM needed to achieve roughly 6 ACH.
Industry guidelines call for a minimum of 4 ACH for general construction and remediation work, with 6 ACH or higher preferred during active demolition, mold remediation, or heavily contaminated environments. Always size the unit to your space's actual cubic footage — not the square footage alone, since ceiling height significantly changes the calculation.
Choosing the Right Air Filtration System
CFM Capacity — Our lineup spans roughly 500 to nearly 2,000 CFM, covering everything from single-room containments up to large commercial and industrial spaces.
Filtration Stages — Multi-stage filtration (pre-filter plus HEPA, with some models adding activated carbon) captures 99.97% of particles at 0.3 microns while extending the life of the primary HEPA filter by catching larger debris first.
Variable Speed Control — Adjustable airflow lets you dial back power for quieter operation in occupied spaces, then ramp up when you need to hit ACH targets quickly on heavier contamination jobs.
Power Source — Standard electric models cover most job sites; pneumatic (air-powered) units are purpose-built for hazardous environments where explosive vapors, combustible dust, or flammable materials rule out standard electric equipment.
Portability — Slim-profile and lightweight models matter when you're moving equipment between floors, tight spaces, or multiple job sites in a day.

Getting the Most from Your Air Filtration System
Calculate ACH Before Choosing Equipment — Size the unit (or combination of units) to your containment's actual cubic footage and required air changes per hour — don't guess based on square footage alone.
Replace Pre-Filters Before the HEPA Stage Clogs — Pre-filters protect the more expensive HEPA filter from heavy dust loading; letting them clog shortens HEPA filter life significantly.
Watch for Filter Change Indicators — Models with pressure gauges or alarm panels take the guesswork out of knowing when performance has dropped due to a loaded filter.
Match Power Source to the Environment — Never use a standard electric unit in an environment with explosive vapors or combustible dust; that's exactly the scenario a pneumatic unit is built for.
Confirm Operating Mode Before Deployment — Not every unit supports both air scrubber and negative air machine modes; confirm your model's capability and static pressure specs before relying on it for containment compliance.
