The short answer

What an Air Scrubber Does

After a fire, smoke particles and volatile compounds linger in the air and settle into porous materials. An industrial air scrubber draws that contaminated air through a series of filters, often including a HEPA filter to capture fine particulates and an activated carbon layer to absorb odors and gases. Some units also use a chemical wash or ultraviolet light to break down remaining pollutants.

The cleaned air is then pushed back into the room, creating a cycle that gradually reduces the concentration of airborne contaminants. This process helps make the air more breathable while you wait for professional fire and water damage restoration. However, the scrubber only works on the air, not on soot that has already deposited on surfaces or soaked into drywall, insulation, or upholstery.

Why You Need Water Damage Cleanup Too

Fire suppression often leaves behind water from sprinklers or hoses, which can soak into floors, walls, and furniture. That moisture creates a separate set of problems, including mold growth and structural weakening. An air scrubber cannot dry wet materials or remove the water trapped inside walls or under flooring.

You need a thorough water damage cleanup process that includes extraction, drying, and disinfecting affected areas. The pros typically use industrial fans, dehumidifiers, and moisture meters to dry out the structure. They also remove and replace damaged materials like drywall or insulation. An air scrubber is one tool in a larger restoration effort, not a standalone solution.

  • Removes smoke particles from the air
  • Neutralizes odors with activated carbon
  • Does not clean soot off surfaces
  • Does not dry water-soaked materials
  • Works well alongside professional cleanup
  • May need to run for days depending on damage

How the Pros Use Air Scrubbers

Local water damage pros often bring in industrial air scrubbers as part of a fire damage restoration plan. They position the unit to create negative air pressure, which prevents contaminated air from spreading to unaffected rooms. The scrubber runs continuously, and the filters are changed regularly as they load up with soot and ash.

The pros also combine the scrubber with other equipment, such as air movers to speed up drying and ozone generators to tackle stubborn smells. The exact setup depends on the size of the fire, the type of materials burned, and how much water was used to put out the flames. You may not see visible results right away, but the air quality should improve over time.

What to Do Right After a Fire

Your first step is safety. Do not re-enter the home until firefighters or a building inspector says it is safe. Smoke and soot can be toxic, and the structure may be unstable. Once you are allowed back in, open windows if possible to ventilate, but do not touch or clean anything until the pros assess the damage.

Contact your insurance company to report the loss and ask about coverage for temporary housing and restoration. Policies vary, and your insurer decides what is covered. Keep a list of damaged items and take photos for documentation. This record helps with the claims process and gives the pros a clear picture of what needs attention.

The Role of Documentation and Assessment

Before any cleanup begins, a professional assessment is critical. The pros inspect the extent of smoke and water damage, identify which materials can be saved, and determine whether structural repairs are needed. They may use moisture meters and thermal imaging to find hidden water pockets.

Documentation is equally important. You should keep receipts for any expenses, such as hotel stays or cleaning supplies, and maintain a written log of all communications with your insurance company. A detailed record helps ensure that nothing is overlooked. If you live in Newark, keep a copy of your home inventory and insurance policy in a safe place outside the house.

Frequently asked questions

Can an air scrubber remove all smoke odors?

An air scrubber can significantly reduce smoke odors, but it may not eliminate them entirely, especially if soot has soaked into porous materials like drywall or carpet. The pros often combine the scrubber with ozone treatment or thermal fogging to tackle deep-set smells. Full odor removal usually requires cleaning or replacing affected surfaces.

How long does an air scrubber need to run?

The running time varies based on the severity of the fire, room size, and the scrubber's capacity. In many cases, the unit runs for several days to a week or more, with filter changes every few days. The pros monitor air quality and adjust the process as needed. You should expect a lengthy restoration process, not a quick fix.

Do I need to leave my home while the scrubber runs?

It is often safer to stay out of the home while the scrubber is operating, especially if the fire was large or involved toxic materials. The pros can advise on when it is safe to return. In the meantime, you should have a place to stay, and your insurance policy may cover temporary housing. Check your policy for details.
