The recent tragedies at Royal Prince Alfred (RPA) and The Children’s Hospital at Westmead (late 2025–early 2026) have sent a shockwave through the Australian healthcare sector.Four lives were lost to hospital-acquired (nosocomial) Aspergillus fungal infections. While the “trigger” is often nearby construction or redevelopment work, the delivery mechanism is almost always the same: The HVAC […]
Welcome back to the Clean-Air Facts Series — your monthly source of concise, science-backed insights into the unseen forces shaping indoor environments.In this second edition, we continue exploring how air quality affects health, comfort, and building performance. Over the past few weeks, we’ve looked at new angles — from how humidity and filtration influence microbial […]
One of the most effective ways to safeguard your HVAC (Heating, Ventilation, and Air Conditioning) Coil and sanitise your airstream is by using UV-C light — a specific bandwidth of ultraviolet light known for its ability to destroy airborne pathogens, mould spores, and bacteria.In this installation, we’ve fitted a UV-C emitter bulb in the supply […]
The Impact of Australia’s Monsoon Season on Indoor Air QualityTorrential rain, flooding and high humidity during the monsoon season can significantly increase the risk of mould outbreaks in buildings. It’s crucial to address this issue promptly to prevent both structural damage and health concerns. Mould thrives in damp environments, and if left unchecked, it can […]
The holiday shutdowns are meant to give everyone a much-needed break, but unoccupied buildings can provide the perfect environment for fungi to thrive. In regions like QLD and NSW, where the typical warm and humid weather creates ideal conditions, the risk of microbial growth—particularly mould—is always present. High humidity, condensation, and reduced airflow during closures […]
With summer around the corner here in tropical and subtropical Queensland, Clean-Air is excited to introduce AERIS MouldGuard™, Mould Stop Paint as a key tool to combat humidity-triggered mould blooms. This powerful, antimicrobial surface finish, suitable for ALL interior surfaces—not just ducting—is tintable and can be applied with a spray gun, paintbrush, or roller.
Classification: BacteriaCultured from / Found in: HVAC Coils, Filters, Grilles and DiffusersAssociated Health Risks: Fever and Swelling of Nose and Throat, Pseudomembrane Diphtheria, Skin Lesions/Infections, Paralysis, Heart Failure Corynebacteria (from the Greek words koryne, meaning club, and bacterion, meaning little rod) are gram-positive, catalase-positive, aerobic or facultatively anaerobic, generally nonmotile rods. The genus contains the species […]
Educating Teams on MouldIn response to the escalating presence of mould in South East Queensland, local Facilities Management teams recently underwent specialised training provided by Clean-Air Australia, renowned experts in mould management. This invaluable session equipped facility management teams with essential knowledge and skills to effectively combat mould issues, enhancing their ability to deliver safe […]
Classification: FunghiCultured from / Found in: HVAC Coils and FiltersAssociated Health Risks: Type III hypersensitivity pneumonitis, Cryptococcal Meningitis, Allergic Alveolitis. About the FunghiBasidiospores develop into many sorts of commonly found mould. These moulds are identifiable by their MVOC (Microbial Volatile Organic Compounds) releases that have a unique musty and condensed smell. As small as 100-120 picometers […]
Overview: Dew Point affects indoor air quality and allergen production. High humidity levels can create a conducive environment for allergens like mould, dust mites, and bacteria to thrive, worsening indoor air quality and potentially triggering allergic reactions. Conversely, maintaining optimal indoor humidity levels can help mitigate allergen proliferation and improve overall air quality.Dew Point is […]
