From ozone generators to today’s indoor air quality solutions. Four generations of technology. One idea that never moved.
Twenty years ago, our parent company, ProMedUSA, was two people and an idea. Today, with over 1,000+ customers across the region, we’re still growing.
On 18 October 2026, ProMedUSA marks twenty years in business. For PurAire Singapore, this milestone celebrates the experience, relationships and practical approach that underpin our work today.
From professional ozone generators to ozonated water, PurAire bipolar ionisation, real-time indoor air quality monitoring and advanced oxidation, the technology has continued to evolve.
The guiding idea has remained the same: understand the problem first, then choose the right solution.
A Singapore Beginning, a Regional Operating History
ProMedUSA began in Singapore on 18 October 2006, bringing practical technologies to customers facing difficult odour and environmental-treatment challenges.
Since then, the company has served more than 1,000 customers across the region, with experience spanning Singapore, Malaysia, Indonesia, Thailand, Vietnam, the Philippines, Hong Kong, mainland China and the Middle East.
That history includes five-star hotel groups, public and private hospitals, international schools and universities, government ministries and defence agencies, airport facilities, shopping malls, offices, restaurants and manufacturing operations.
Behind every project is a working facility, a different set of operating conditions and people who need a solution they can manage long after installation.
PurAire Singapore carries that experience forward into its approach to indoor air quality.
Where the Journey Began: Professional Ozone Treatment
ProMedUSA’s early work centred on persistent odours—the kind that ordinary cleaning or fragrance could not resolve.
Professional ozone generators provided a specialised tool for controlled treatment applications, including guest rooms, bin centres and other commercial environments.
Those projects established an important lesson: supplying equipment is only part of solving the problem.
Understanding the source, the space and its operating conditions matters just as much.
Was the odour embedded in furnishings? Was a source continually generating it? Were humidity, airflow or maintenance contributing to the complaint?
Professional ozone treatment remains part of ProMedUSA’s portfolio. Room treatment requires unoccupied spaces, appropriate operating procedures and safe re-entry after treatment.
That experience helped shape the application-led approach that PurAire follows today.
Expanding Into Ozonated Water
ProMedUSA subsequently broadened its capabilities through ozonated-water technologies for cleaning, deodorising and surface applications.
Systems such as the SG-OzPAK portable ozonated-water jet spray, SG-WDS and Tersano Stabilised Aqueous Ozone introduced another way to support housekeeping teams, commercial kitchens and facilities operations.
These technologies can help reduce reliance on conventional cleaning chemicals in appropriate applications. Equipment selection, operating instructions, surface suitability and required contact time remain important.
This expansion moved the company beyond airborne odour treatment into a broader understanding of how environmental technologies fit into everyday operations.
A solution must suit the people using it as well as the problem it addresses.
The PurAire Chapter: Bipolar Ionisation for Occupied Spaces
Hotels, hospitals, offices and schools presented a different challenge: how could indoor air be treated in spaces that needed to remain occupied?
ProMedUSA’s expansion into Glass DBD bipolar ionisation, through PurAire Singapore, broadened the options available.
Today, the PurAire range includes solutions for individual rooms and toilets, lifts, fan-coil units, ceiling cassette air-conditioning systems and larger HVAC installations, alongside portable products for selected applications. Over 30 different models guaranteeing the correct fit for every sized application – not 1 size fits all.
Professional ozone treatment and bipolar ionisation serve different purposes. Selecting the appropriate technology requires attention to the application, occupancy and individual model’s requirements.
For PurAire, the principle remains clear: match the solution to the facility and the problem.
Today: Monitoring, Advanced Oxidation and Broader Capabilities
The next stage of the journey brings treatment together with a deeper understanding of indoor environmental conditions.
An odour complaint may be readily apparent. Other concerns require measurement. Depending on the instrument and sensor configuration, monitoring can provide information about particles, carbon dioxide, volatile organic compounds, temperature, humidity or specific gases.
Through the wider ProMedUSA portfolio, our team draws on Atmocube, Kaiterra, Aeroqual and EcoSensors instruments, selected according to the monitoring application.
We begin by understanding the site. Where measurement is needed, it helps identify the problem and assess the result of corrective action.
The broader portfolio also includes RestorAir advanced-oxidation equipment, Novita air purifiers and dehumidifiers, kitchen-exhaust treatment, aquatic life support and industrial water-treatment systems.
This breadth gives our team access to complementary approaches. An indoor environmental complaint may require source control, ventilation, filtration, humidity management, specialist treatment or a combination.
There is no single product that solves every indoor air quality problem.
Four Generations of Technology. One Idea That Never Changed
The technology kept changing.
Professional ozone generators for stubborn odours. Then ozonated water to support cleaning and surface applications. Then our own PurAire bipolar ionisation, including fixed systems for spaces that cannot go offline. And today, real-time air quality monitoring and advanced oxidation.
Together, PurAire Singapore and its parent company, ProMedUSA, bring these capabilities together:
- ProMedUSA Ozone Generators
- PurAire Bipolar Ionisers
- RestorAir RRR-AOC-26
- AZCO, Clearwater Tech and Absolute Ozone systems
- SG-OzPAK and Tersano Stabilised Aqueous Ozonated Water systems
- Kitchen-exhaust odour and grease-control systems
- Kaiterra and Atmocube IAQ monitors
- Aeroqual and EcoSensors instruments
- Novita Air Purifiers and Dehumidifiers
Each expansion adds another option. The purpose remains consistent: understand the problem, choose
an appropriate solution and make it practical for the building and the people operating it.
What Twenty Years in Solving IAQ Issues in Singapore Has Taught
Us
Experience continues after installation. Equipment must suit the facility, its airflow, its operating conditions and the people maintaining it.
Four lessons guide our approach:
Start with the source. Understand what is causing the complaint before selecting equipment.
Match the technology. Choose an approach suited to the problem, the application and occupancy.
Respect the building. Humidity, airflow, equipment placement and operating conditions affect performance.
Plan beyond installation. Maintenance, operating guidance and ongoing support belong in the solution from the beginning.
Sometimes the appropriate next step is treatment equipment. Sometimes it is improved ventilation, a maintenance change or further investigation.
Our role is to help customers identify that next step.
Thank You for Twenty Years of Trust
For PurAire Singapore, celebrating ProMedUSA’s twentieth anniversary means recognising the people behind the journey.
