The short answer
How an Air Scrubber Works
An air scrubber draws in room air through a fan, passes it through a series of filters, and then releases cleaner air back into the space. The most common type uses a HEPA filter to capture fine particles like mold spores, dust, and soot. A carbon filter may be added to absorb odors from stagnant water or smoke.
The machine creates a slight negative pressure in the room, which keeps contaminated air from drifting into other parts of your home. This is especially useful during water damage cleanup, when drywall dust and microbial growth can become airborne. The scrubbed air helps protect your respiratory health while the pros handle the physical work.
When You Might Need One
After a flood, burst pipe, or sewage backup, the air in your home can hold particles that irritate your lungs. An air scrubber is most helpful during and after the drying phase, when materials like carpet, drywall, and wood are disturbed. It also reduces lingering musty smells that often follow water exposure.
If you have asthma or allergies, running an air scrubber can make the environment more comfortable while repairs are underway. However, the machine is not a substitute for removing wet materials or fixing the source of the water. It works alongside drying equipment, not in place of it.
- Traps mold spores and dust particles
- Reduces odors from damp materials
- Helps contain airborne contaminants
- Supports the drying process
- Useful during demolition and cleanup
- Not a replacement for water extraction
Limitations of Air Scrubbers
An air scrubber cannot dry out wet walls, floors, or furniture. It only cleans the air that passes through it, so it does nothing to remove standing water or lower humidity. For that, you need dehumidifiers and air movers, which the pros often set up as part of a full drying plan.
The filters need regular changing, especially in dusty conditions. If the machine is used in a room with heavy mold growth, the filter may clog quickly. You should keep windows and doors closed while it runs to maintain the negative pressure effect.
Renting vs. Buying
You can rent an air scrubber from equipment rental stores or buy a smaller unit for home use. Renting makes sense for a one-time cleanup after a major water event. Buying a unit might be useful if you deal with recurring moisture issues, but it adds to your equipment collection.
Cost depends on the unit size, filter type, and rental duration. A typical rental often ranges from $50 to $150 per day, but the final price depends on your location, the specific model, and how long you need it. For a large area, you may need more than one machine, which increases the expense.
When to Call the Pros
For significant water damage, the pros bring industrial-grade air scrubbers along with air movers and dehumidifiers. They also handle the messy work of removing wet carpet, drywall, and insulation. If you suspect mold growth or have health concerns, do not wait to start cleanup.
The pros will assess the extent of the damage and set up equipment that matches the size of the affected area. They also know how to dispose of contaminated materials safely. If you live in Mesa, keep your local water damage pros contact info handy for emergencies.
- Large flooded areas need industrial equipment
- Mold growth may require professional handling
- Hidden moisture in walls needs detection
- Proper containment prevents cross-contamination
- Safety gear and disposal are handled by the pros

Can an air scrubber remove mold spores?
Yes, a HEPA-equipped air scrubber can capture mold spores that are floating in the air. However, it does not kill mold or remove it from surfaces. You still need to clean and dry affected materials to prevent further growth.
How long should I run an air scrubber?
Run it continuously during active cleanup and for at least 24 to 48 hours after the source of water is removed. The exact time depends on the room size and the level of contamination. Keep it running until odors and dust are noticeably reduced.
Is an air scrubber the same as a dehumidifier?
No. A dehumidifier removes moisture from the air, while an air scrubber filters particles and odors. Both are often used together after water damage to dry the space and improve air quality. You may need both for a complete cleanup.
