The short answer
What Is an Air Scrubber
An air scrubber is a portable filtration device designed to clean the air in a contained space. It uses a powerful fan to draw air in, passing it through several stages of filters before exhausting cleaner air. These machines are commonly deployed during mold or water damage restoration to control airborne particulate. They are a key tool for maintaining air quality during cleanup, but they are only one part of a complete remediation plan. Their primary function is to manage the air you are breathing while the source problem is being addressed.
The Role of the HEPA Filter
The High-Efficiency Particulate Air (HEPA) filter is the component that actually captures mold spores. This dense filter is made of interlaced glass fibers that create a maze for air to pass through. Particles like mold spores, pollen, and dust become trapped in the fibers. These filters are designed to capture an extremely high percentage of very small particles, which is why they are essential for filtering out mold spores from the air.
The Complete Filtration Process
Air scrubbers often use a multi-stage process. Air first passes through a pre-filter that catches larger debris like dust and hair, protecting the main HEPA filter. It then moves through the HEPA filter for fine particulate removal. Some units include an activated carbon filter to adsorb odors and volatile organic compounds. This staged approach ensures efficient operation and longer filter life. The machine continuously cycles the room's air, pulling in contaminated air and pushing out cleaner air dozens of times per hour.
- A fan pulls contaminated air into the machine.
- A pre-filter captures large debris and protects the HEPA filter.
- The HEPA filter traps microscopic mold spores and other fine particles.
- An optional carbon filter can remove odors from the air.
- Clean, filtered air is then exhausted back into the room.
- This cycle repeats, continually lowering the spore count in the air.
When Air Scrubbers Are Used for Mold
Local water damage pros use air scrubbers when actively disturbing mold during remediation, such as removing contaminated drywall or carpet. The machines help prevent spores from spreading to clean areas of your home. They are typically set up to create negative air pressure in the work zone. This means air flows into the contained area, not out of it, which is a standard practice for safe and effective mold removal. The scrubbers run throughout the demolition and cleaning process.
Limitations and Important Considerations
An air scrubber filters the air but does not kill mold or remove it from surfaces. The source of the moisture must be fixed, and all moldy materials must be properly cleaned or discarded by a qualified professional. Running an air scrubber alone is not a complete solution for a mold problem. It is a tool for containment during the larger remediation process. If you turn off the scrubber and the underlying moisture and mold remain, the spores will return to the air. Professional assessment and source removal are non-negotiable steps.

Can I rent an air scrubber and clean the mold myself?
DIY mold cleanup is risky. Disturbing mold without proper containment can spread spores. A mold professional assesses the extent, fixes the moisture source, and removes contaminated materials safely. Improper handling can lead to recurring mold or health issues.
How long should an air scrubber run?
The pros typically run air scrubbers for the entire duration of active work and often for a period after. The exact time depends on the project's size and the initial spore levels. They use air quality testing to determine when it is safe to stop.
Will an air scrubber remove the mold smell?
A standard HEPA filter does not remove odors. Some air scrubbers have an added activated carbon filter stage designed to adsorb musty smells and chemicals. For persistent odors, the source mold must be completely removed, and the area dried thoroughly.
