The short answer
How Air Scrubbers Work
An air scrubber draws in surrounding air and passes it through a series of filters. The first filter catches larger debris like dust and pet hair, while a finer filter traps smaller particles such as mold spores and pollen. Some units also use activated carbon to absorb odors from damp or musty spaces.
The cleaned air is then pushed back into the room, creating a continuous cycle. This helps reduce the number of airborne irritants while the space is being dried and repaired. The unit does not remove water from materials, but it can make the environment more comfortable to work in.
When You Might See One
After a leak, flood, or heavy condensation, you may notice an air scrubber placed in the affected room. It is often used alongside dehumidifiers and air movers to speed up drying and control odors. You might also see one during mold cleanup or after a fire to help clear smoke particles.
The pros typically run these units for days or weeks, depending on the extent of the damage. You can ask the pros about the plan for your home. They will explain why the unit is needed and how long it might stay in place.
- Reduces airborne dust and debris
- Helps control musty odors
- Traps mold spores and pollen
- Works well with dehumidifiers
- Useful during structural drying
- Not a substitute for removing water
Air Scrubber vs Air Purifier
An air purifier is designed for everyday use in a single room, often with a HEPA filter to remove allergens. An air scrubber is more powerful and built for temporary, heavy-duty situations like water damage or construction. It moves a larger volume of air and may have multiple filter stages.
For a home after a leak, an air scrubber can handle higher particle loads than a typical purifier. The pros may bring in several units to cover a large area. You do not need to buy one; the pros usually supply the equipment as part of the drying process.
Rental or Purchase Options
You can rent an air scrubber from equipment rental stores if you plan to dry out a space yourself. Rental costs vary, but it might be more practical to let the pros handle it, especially for large or complex jobs. The cost depends on the unit size, rental duration, and your location.
If you buy a unit, you will need to maintain it by changing filters regularly. Follow the manufacturer's instructions for filter replacement. For most water damage situations, renting or using a service is simpler than owning one.
Safety and Maintenance Notes
An air scrubber can improve air quality, but it does not replace the need to remove wet materials and dry the structure. Mold can grow inside walls or under flooring if moisture remains. Always wear gloves and a mask when handling water-damaged items.
If you feel unwell from odors or particles, see a doctor. Keep the unit away from water sources to avoid electrical hazards. Check the filters regularly for clogs. The pros will handle all maintenance if they set up the unit for you.

Do I need an air scrubber after a small leak?
For a small, quickly dried leak, you might not need one. But if you notice musty smells or lingering dust, an air scrubber can help. The pros can assess the situation and recommend if one is necessary. It depends on the extent of the damage.
How long should an air scrubber run?
It depends on the size of the area and the level of contamination. The pros may run it for several days to a few weeks. They will monitor air quality and adjust the plan. You can ask them for an estimated timeline.
Can an air scrubber remove mold spores?
Yes, a HEPA filter can trap mold spores, but it does not kill mold. The source of moisture must be fixed, and affected materials must be dried or removed. The pros will handle the mold cleanup separately if needed.
