Airborne particles can become a serious concern during restoration, remediation, construction and intensive cleaning work.
Dust and fine material may remain suspended in the air and travel beyond the immediate work area.
An air scrubber is designed to draw in contaminated air, pass it through a filtration system and return filtered air to the space.
Where are air scrubbers used?
Professional air scrubbers may be used during:
- Water-damage restoration
- Mould remediation
- Construction and renovation
- Dust-producing work
- Fire and smoke restoration
- Odour-control projects
- Building maintenance
- Cleaning of sensitive environments
The correct filtration setup depends on the work being performed and the hazards present.
Understanding filtration
Many air scrubbers use multiple filtration stages.
A pre-filter captures larger particles and helps protect the more expensive main filter. The primary filter then captures finer airborne material.
Some machines may also support optional activated-carbon filters for certain odours and gaseous contaminants.
Filters must be installed correctly and replaced when loaded. A dirty filter can restrict airflow and reduce the machine’s effectiveness.
Negative-air applications
Some air scrubbers can be connected to ducting to create a negative-pressure environment inside a contained work area.
This helps reduce the movement of airborne contaminants into surrounding spaces.
Negative-air setups should be planned carefully by trained professionals. The required airflow, containment design and pressure relationship will depend on the size and risk of the project.
Air scrubbing does not replace source control
An air scrubber is one part of a complete process.
Contaminated materials may still need to be removed, cleaned or treated. Work areas may need to be contained, and personal protective equipment may be required.
Air filtration should support—not replace—appropriate remediation procedures.
Choose equipment for the job
When selecting an air scrubber, consider:
- Airflow capacity
- Room size
- Filter type
- Variable-speed settings
- Ducting options
- Power requirements
- Portability
- Availability of replacement filters
The machine must also be maintained between projects to avoid transferring contamination from one site to another.
Cleanstar and XPOWER Australia supply professional air scrubbers, filters, air movers, dehumidifiers and restoration equipment.
For restoration contractors and building professionals, effective air management can support a cleaner, more controlled working environment.
