The Science Behind Gelair
Harnessing the natural antimicrobial and antifungal properties of pure Australian Tea Tree Oil to create cleaner and healthier environments.
Gelair technology combines nature and science to continuously purify the air, protect surfaces and support healthier indoor spaces.
How it works
Australian Tea Tree Oil is a natural antimicrobial and antifungal agent. When the Gelair vapour or liquid encounters microorganisms, it disrupts their cellular structure, helping to control and prevent the spread of harmful bacteria including Legionella pneumophila (Legionella), mould (including hidden mould), and enveloped viruses such as COVID (SARS-CoV-2), RSV, hantavirus and Influenza A and B.
By continuously dispersing Tea Tree Oil vapour throughout the system or indoor environment, Gelair products provide ongoing treatment of both visible and hidden areas, supporting cleaner air and healthier indoor environments.
Gelair™ products are offered in biodegradable gel, foam and liquid matrixes and are specially formulated with pure Australian Tea Tree Oil. The gel and foam products work by releasing vaporised Tea Tree Oil, ensuring consistent and effective performance.
When placed within an air-conditioner or indoor environment, the gel and foam matrixes release a controlled and sustained concentration of Tea Tree Oil vapour over time.
In air-conditioning systems, as air flows across the surface of the product, the vapour is carried throughout the system and into the indoor space allowing Gelair to treat not only the air, but also the system’s internal components - delivering complete, 360° treatment for the entire system and the rooms it serves.
Enveloped vs Non-enveloped Viruses

Research, testing & case studies
Gelair products are supported by a combination of scientific research, independent testing and real-world application. We are committed to ensuring each product performs to a high standard and delivers consistent, reliable results.
The effectiveness of all Gelair solutions is underpinned by established research into the antimicrobial, antiviral and antifungal properties of Australian Tea Tree Oil, laboratory testing of individual product performance and field-based case studies.
Independent university research supports the efficacy of Tea Tree Oil in both liquid and vapour form for hygienically treating air and surfaces.
We commission independent testing to assess the performance of specific Gelair products in controlling airborne microorganisms, with Gelair products among the most extensively tested in the industry.
In addition, case studies have demonstrated measurable reductions in airborne bacteria following installation in a range of indoor environments, such as hospitals.
Standards & certifications
We develop and manufacture our products in line with recognised industry standards and quality practices. Maintaining these standards, and actively supporting the industry through relevant associations, is a key part of our commitment to delivering consistent, reliable Tea Tree Oil solutions.
We believe it is important to support Australian Tea Tree plantation growers and contribute to the ongoing development and integrity of the Australian Tea Tree industry.
