An air scrubber is a powerful air-cleaning device designed to remove contaminants, particles, and odors from the air, especially in industrial, restoration, and construction environments where air quality can become very poor.

What an Air Scrubber Does

In simple terms, an air scrubber pulls in dirty air, which is filtered through multiple stages (three filtration system), and then clean air is released back into the space. It's like a supercharged air purifier used in tougher environments. Generally, an air scrubber is used for construction sites, decoration sites, basements, underground garages, flood restoration houses, etc.

 

How an Air Scrubber Works

Air Intake

The scrubber's fan draws in surrounding air filled with dust, mold spores, smoke, or chemical fumes.

Filtration Process

The air passes through several filters:

Pre-filter: Catches larger particles (dust, hair, debris).

HEPA filter (High Efficiency Particulate Air): Captures 99.97% of particles as small as 0.3 microns, including mold, pollen, bacteria, and smoke.

Activated Carbon filter: Removes odors, volatile organic compounds (VOCs), and chemical fumes.

Clean Air Output

The filtered, clean air is then released back into the room or vented outside through ducting (common on job sites).

 

Typical Uses of Air Scrubbers

Application	Purpose
Mold Remediation / Water Damage Restoration	Removes mold spores and airborne contaminants stirred up during cleanup.
Construction & Renovation Sites	Captures drywall dust, paint fumes, and fine debris.
Hospitals & Clinics	Maintains sterile air quality.
Fire or Smoke Damage Cleanup	Filters out smoke particles and odor.
Commercial Buildings & Warehouses	Improves indoor air quality where HVAC alone isn't enough.

 

Negative Air Setup

In some cases, air scrubbers are connected to ducts leading outdoors, creating negative air pressure in a contaminated area.

This setup prevents dirty air from spreading to clean zones — crucial in mold removal, asbestos abatement, or hospital isolation rooms.

 

Air Scrubber vs. Air Purifier

Preair provides high-quality HEPA air scrubbers for sale. It is recommended to purchase AF650 air scrubbers for commercial use. The fan speed of the AF650 is 500-2400 RPM. The motor rating is 1/3 HP. The air volume is 250-500 CFM. CONTACT US if you want to know more details.
