Following professional mould remediation, the final step to ensuring your home is safe is to address what remains in the air. Microscopic mould spores, often dislodged during removal work, can linger and circulate. Our air treatment service is a crucial final stage designed specifically for Townsville’s challenging climate, using high-efficiency particulate air (HEPA) scrubbers to capture these airborne contaminants and verify the air quality of your property.

This service is not a standalone “mould fix.” It is the concluding step of a proper remediation project that follows the IICRC S520 standard, the industry benchmark for professional mould remediation.

Verifying Air Safety After Mould Removal in
North Queensland's Climate

Townsville’s environment, with its prolonged humidity during the wet season, creates a persistent threat. After an event like a plumbing leak in a Kirwan apartment or storm water ingress in a home in Rosslea, simply removing the visible mould isn’t enough. Spores from common local species like Aspergillus or Cladosporium can become airborne, ready to settle in a new location.

Our process targets these invisible threats. We often deploy our equipment after remediating water damage in properties across the city, from older homes in Railway Estate to newer builds in Annandale. This final air-scrubbing step is what provides confidence that spore counts have been returned to normal, background levels.

How We "Scrub" Your Indoor Air

Our process is methodical and grounded in building science. We don’t just place a filter in a room; we create controlled airflow to capture and remove particulates effectively.

Containment and Negative Air Pressure

We first ensure the remediated area is properly isolated. Using HEPA air scrubbers, we can establish negative air pressure, preventing airborne spores from escaping the work zone into unaffected parts of your property.

HEPA Filtration

We use commercial-grade HEPA 500 air scrubbers. These units are certified to capture 99.97% of all airborne particles down to 0.3 microns. This efficiency is critical for trapping mould spores, which typically range from 2-20 microns.

Sufficient Air Exchange

We calculate the required number of units and running time to achieve multiple complete air changes per hour (ACH), ensuring the entire volume of air in the space passes through our filters repeatedly.

Optional Post-Treatment Verification

For ultimate assurance, we can conduct post-remediation air sampling to provide laboratory confirmation that the spore count is within acceptable limits, compliant with the IICRC S520 standard.

Air Treatment is NOT a Substitute for Mould Removal

It is critical to understand that air treatment does not remove mould growing on surfaces. Running an air scrubber in a room with an active mould problem is ineffective. The source of the moisture must be fixed and the mould must be physically removed first. Our service is designed to be used after the following steps have been completed:

The initial water or humidity source has been found and repaired.
All visible mould and contaminated materials have been physically removed and disposed of according to industry standards.
The remediated area has been thoroughly cleaned with HEPA vacuums.

Frequently Asked Questions

What kind of equipment do you use?

We use industry-standard HEPA air scrubbers, often referred to as negative air machines. These are powerful, portable filtration units equipped with pre-filters for large particles and a final HEPA filter certified to capture 99.97% of particles at 0.3 microns.

How do you know the air is clean?

The effectiveness is based on the proven science of HEPA filtration and achieving a sufficient number of air changes per hour. For an additional fee, we can use an independent laboratory to conduct air sampling before and after treatment to provide quantifiable data on the spore count reduction.

Does this remove the musty smell?

Partially. Musty odours (MVOCs) are gases released by mould. While HEPA filters trap the spores, removing the odour may require adding activated carbon filters to our air scrubbers, which we can do upon request. The primary way to eliminate the odour is to remove the mould source itself.

Is air treatment required after every mould job?

Not always, but it is highly recommended for any project involving more than a small, isolated area of surface mould. It is considered essential for any remediation following significant water damage, like that seen after the 2019 floods, or where occupants have known sensitivities.
