Air Scrubbers

Air scrubbers filter airborne contaminants through true HEPA filtration that captures 99.97% of particles at 0.3 microns, including mold spores, asbestos fibers, construction dust, and bacteria. HEPA-filtered air scrubbers are required by IICRC S500 and EPA mold remediation protocols for containment zones where negative air pressure must be maintained. Browse Abatement Technologies and XPOWER models from 500 to 2,000 CFM for restoration, remediation, and construction applications.

Air Scrubbers with HEPA Filtration for Mold, Dust, and Restoration Work

When Does a Job Site Require an Air Scrubber?

An air scrubber pulls contaminated air through a filter stack, removes particulate down to 0.3 microns, and discharges clean air back into the space or exhausts it to the exterior. Mold remediation, post-flood drying, asbestos abatement, lead paint removal, and active demolition all generate airborne hazards that require active air filtration to meet regulatory thresholds. The EPA mold remediation guide for commercial buildings specifies that air scrubbers with HEPA filtration must be used during active mold removal to maintain negative pressure containment and prevent cross-contamination. Abatement Technologies and XPOWER manufacture the units in this collection specifically for these conditions.

How Many CFM Do You Need for Negative Air Pressure?

Commercial air scrubbers are rated in CFM (cubic feet per minute). The standard for mold remediation, established in IICRC S520 mold remediation standards, requires a minimum of six air changes per hour in the containment zone. Calculate the room volume in cubic feet, multiply by six, and divide by 60 to get the minimum CFM requirement. Most professional units start at 500 to 2,000 CFM, providing substantial margin over the minimum and allowing for negative pressure setups where the scrubber exhausts to the exterior at a rate that keeps containment at lower pressure than surrounding spaces. Negative pressure prevents contaminated air from escaping through containment seams. Three-stage filtration, a pre-filter for large particles, a carbon stage for odors and VOCs, and a final HEPA stage is the configuration required for mold and chemical exposure work. Units with only HEPA filtration skip the carbon stage, making them appropriate for construction dust but not for work involving mycotoxins, formaldehyde, or solvent vapors.

Which Unit Fits Water Damage vs Construction Dust?

Water damage restoration and construction dust control share the same equipment category but pull from different ends of the specification range. Restoration work demands true three-stage HEPA units, robust housing that tolerates wet environments and repeated transport, and CFM output sufficient to maintain negative pressure in containment. XPOWER units in this collection cover mid-range CFM needs for residential and light commercial water damage projects. Abatement Technologies machines are specified for larger commercial structures and hazmat-adjacent environments where filter certification documentation, unit labeling, and housing durability are requirements from the project owner or insurer. Construction dust applications, drywall cutting, concrete grinding, or general demolition without known hazardous materials, can often be addressed with simpler units at lower CFM ratings, since the goal is dust capture rather than negative pressure containment. The OSHA silica dust standards for construction specify that air filtration equipment used during silica-generating tasks must meet defined capture efficiency thresholds, so confirming the unit's filter rating against the task type keeps the job site in compliance. Keep the pre, carbon, and HEPA stages in stock with replacement air scrubber filters sized to each unit.

Frequently Asked Questions

What's the difference between air scrubbers and negative air machines?
Air scrubbers and negative air machines both use HEPA filtration, but negative air machines create negative pressure to contain airborne contaminants within a work area. Air scrubbers focus on filtering and recirculating air. For containment in mold remediation or asbestos abatement, negative air machines are required.
Do I need HEPA filtration for mold remediation?
Yes, HEPA filtration is essential for mold remediation as it captures 99.97% of particles 0.3 microns or larger, including mold spores. This prevents cross-contamination to clean areas and protects workers from inhaling harmful spores during the remediation process.
How many air scrubbers do I need for my project?
A general rule is one air scrubber per 2,000-3,000 cubic feet for standard remediation. For heavy contamination or asbestos abatement, increase coverage to one unit per 1,000-1,500 cubic feet. Always check local regulations and industry guidelines for specific requirements.
Can air scrubbers remove odors?
Standard HEPA air scrubbers remove particles but not odors. For odor removal, look for models with activated carbon filters or UV-C light technology. These additional filtration stages neutralize odors from smoke, mold, and other sources while maintaining particle filtration.
How often should HEPA filters be replaced?
HEPA filter replacement depends on usage and contamination levels. For heavy remediation work, filters may need replacement every 3-6 months. Light commercial use may extend to 12-18 months. Always check the pressure gauge - when it indicates high resistance, it's time to replace filters regardless of time elapsed.
