What Is an Air Scrubber Used for in Restoration?
Last updated October 25, 2026
The short answer
How Air Scrubbers Work
An air scrubber pulls in air from the room and passes it through a series of filters. The filters trap fine particles like dust, soot, and mold spores. Some units also use activated carbon to absorb odors from stagnant water or damp materials. The cleaned air is then pushed back into the space, creating a cycle that gradually reduces airborne contaminants.
During water damage, the air can hold moisture and microscopic particles that settle on walls, furniture, and ducts. Running an air scrubber helps the pros control the environment while they remove wet materials and dry out the structure. It is not the same as a dehumidifier, though both are often used together. The scrubber focuses on cleaning the air, while a dehumidifier pulls out moisture.
Why You Might Need One
After a leak or flood, your home can smell musty and the air may feel heavy. An air scrubber helps reduce that smell and clears out particles that can irritate your nose or throat. If you have allergies or asthma, cleaner air makes the space more comfortable while the restoration work goes on.
The pros often place air scrubbers in the affected room or near the drying equipment. The unit runs for hours or days, depending on the size of the area and the level of damage. You may see it connected to a hose that vents outside, which helps push contaminated air out and bring in fresh air. This setup can also help control odors and reduce the spread of particles to other rooms.
- Removes dust and dirt from the air
- Captures mold spores during cleanup
- Reduces musty odors from dampness
- Helps protect your furniture and electronics
- Often used with air movers and dehumidifiers
- Runs quietly in the background
Air Scrubbers vs. Air Purifiers
Air purifiers are designed for everyday use in homes to remove allergens and smoke. Air scrubbers are more powerful and built for heavy-duty situations like water damage, fire cleanup, or mold remediation. They move a higher volume of air and often use stronger filters, including HEPA and carbon stages. The choice depends on the scale of the problem and the level of filtration needed.
For a small spill, a home purifier might be enough. But after a major flood or a sewage backup, the pros will likely bring in industrial-grade scrubbers. These units can handle large spaces and run continuously for days. If you are unsure which one you need, ask the pros what they recommend for your specific situation. They can also explain the differences in filter types and how long each might last.
What to Expect During Restoration
When the pros assess the extent of the water damage, they decide where to place the air scrubber. They may set it up in the most affected room or near the source of the leak. The unit runs while they remove wet carpet, drywall, and insulation, and while they set up drying equipment.
You might notice the air feels cleaner and the smell fades as the scrubber works. The pros will monitor the air quality and adjust the setup as needed. In some cases, they may use multiple scrubbers for larger areas or to create a negative air pressure zone, which prevents contaminated air from spreading to other parts of your home.
- The unit is portable and can be moved as needed
- Filters may need to be changed during long jobs
- The scrubber runs until the air meets safety standards
- You can usually stay in the home, but ask the pros for guidance
- It helps reduce the risk of mold growth after drying
After the Scrubber Is Gone
Once the restoration work is done, the pros will remove the air scrubber and other equipment. The air should be clear and without lingering odors. You may want to open windows for a few hours to let in fresh air, especially if the weather is mild. In humid climates, you might prefer to run your HVAC system to keep the air moving.

Can I rent an air scrubber myself?
You can rent air scrubbers from equipment rental shops, but you need to know the right size and filter type for your space. The pros have training to set them up correctly and know how long to run them. For significant water damage, it is often safer to let the pros handle it.
How long does an air scrubber need to run?
The running time depends on the extent of the damage and the size of the area. For a small leak, it might run for a day or two. For a major flood, it could run for a week or more. The pros will monitor the air quality and decide when it is safe to stop.
Is an air scrubber safe for pets?
Air scrubbers are generally safe for pets because they do not release chemicals. The unit just filters the air. However, the noise and airflow might startle some animals. Keep pets away from the equipment and the work area to avoid any accidents. If you have concerns, talk to the pros.
