Air Treatment & Spore Reduction For Cairns Properties

In Cairns, simply removing visible mould is not enough. The high humidity, especially during the wet season from November to April, creates a persistent threat of re-contamination from airborne spores. Our air treatment service is a critical final step after physical mould removal, designed specifically to capture the microscopic spores that inevitably become aerosolized during cleaning and remediation.
This isn’t a standalone “fogging” solution. It is a methodical process recommended only after a thorough inspection and remediation, conforming to the ANSI/IICRC S520 Standard for Professional Mold Remediation. Our goal is to reduce the concentration of airborne particulates, a common issue in rental properties in suburbs like Manoora and older homes in Edge Hill known for ventilation challenges.
Why Airborne Spore Levels Remain High After Initial Mould Removal
Mould colonies, when disturbed, release millions of spores into the air. In the enclosed environments of modern apartments in Cairns North or the still air of a block home in Woree, these spores can linger for days, settling on surfaces and finding new moisture to colonize.
Our service directly addresses this post-remediation risk. We have documented cases in post-cyclone repairs where, even after drywall was replaced, elevated spore counts from species like Aspergillus and Penicillium were detected in the air, originating from disturbed but untreated cavities. Air scrubbing captures these lingering particles before they can establish new growth.
Our technicians use commercial HEPA 500 air scrubbers. These are not retail air purifiers. Each unit is rated to capture 99.97% of particles down to 0.3 microns, including the most common mould spores. By establishing negative air pressure and calculating the necessary air changes per hour (ACH) for a given space, we create a controlled environment that systematically filters the entire volume of air within a room.
Our Air Scrubbing Process: What to Expect
Is Air Scrubbing Always Necessary in Cairns?
Not always. We recommend air treatment based on specific findings from our initial inspection and moisture assessment. It is most critical in situations involving:
Large-scale contamination (typically over one square metre)
HVAC system contamination, which can spread spores property-wide
Occupants with known sensitivities or respiratory conditions.
Properties with persistent humidity or historic water intrusion, common in low-lying suburbs or older Queenslander-style homes
We provide a clear explanation of its purpose and limitations so you can make an informed decision for your property.
Air Treatment FAQs
What is the difference between air treatment and an ozone generator?
Air scrubbing is a physical filtration process that traps and removes spores from the air. Ozone generation is a chemical process that attempts to kill spores but can be hazardous to occupants and damaging to materials. As IICRC-certified remediators, we rely on physical removal via HEPA filtration, not ozone.
Does air treatment remove the musty smell?
Partially. The musty smell is caused by Microbial Volatile Organic Compounds (MVOCs) released by active mould. By removing the airborne spores and allowing the area to dry, the smell typically dissipates. For persistent odours, activated carbon filters can be added to our air scrubbers.
Can I stay in my home during air treatment?
The treatment is confined to the contained area. It is perfectly safe to be in other parts of the home while the air scrubbers are running.
Final Air Quality Verification for Your Property
If post-remediation air sampling was part of your initial scope of work, our team will arrange it after the air scrubbing is complete. This provides independent verification that spore counts have been reduced to acceptable levels.
