Twenty years ago, ProMedUSA was two people and an idea.
On 18 October 2006, we began in Singapore with a practical ambition: bring technologies to market that could solve difficult odour and indoor environmental problems, while helping customers reduce reliance on conventional cleaning chemicals where appropriate.
On 18 October 2026, we mark twenty years in business.
What began as a small company has grown into an operating history across Singapore, Malaysia, Indonesia, Thailand, Vietnam, the Philippines, Hong Kong, mainland China and the Middle East.
OVER 1,000 CUSTOMERS ACROSS THE REGION.
Our customers have included 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 that reach are individual buildings, different operating conditions and people who needed practical answers. This anniversary is a celebration of the experience those projects have given us — and the trust that made them possible.
It Started With Odours
In the early years, the problem we encountered again and again was persistent odour: the kind that ordinary cleaning or fragrance could not resolve.
Our work centred on professional ozone generators for controlled treatment applications. Hotels needed help with guest-room odours. Commercial facilities faced difficult bin-centre and service-area complaints. Other customers needed equipment suited to demanding environmental-treatment applications.
Those projects taught us that supplying a machine was only part of the job. We also needed to understand the source of the complaint, the space being treated and the conditions in which the equipment would operate.
Was the odour embedded in furnishings? Was a source continually generating it? What role did humidity, airflow or maintenance play?
Professional ozone treatment remains part of our portfolio. For room treatment, it requires unoccupied spaces, appropriate operating procedures and safe re-entry after treatment. It is a specialised tool, selected for the application.
That early experience established a principle that still guides us: understand the problem first, then choose the technology.
From Air to Water
Our portfolio expanded to include ozonated-water technologies for cleaning, deodorising and surface applications.
This opened another way to support hotels, commercial kitchens, healthcare facilities and housekeeping teams. Instead of focusing only on airborne odours, we could help address suitable washable surfaces and cleaning routines.
Our range includes the SG-OzPAK portable ozonated-water jet spray, SG-WDS systems and Tersano Stabilised Aqueous Ozone solutions.
These technologies can help customers reduce reliance on conventional cleaning chemicals in appropriate applications. The correct system, operating instructions and required contact time remain important to the result.
For ProMedUSA, this expansion reflected a broader shift: from supplying individual pieces of equipment to understanding how environmental technologies fit into everyday building operations.
A solution has to work for the people using it, as well as for the problem it is intended to address.
The PurAire Chapter: Air Treatment in Occupied Spaces
Hotels, hospitals, offices and schools raised another question: what could be done in spaces that needed to remain occupied?
Our development into Glass DBD bipolar ionisation, through PurAire Singapore, expanded the options available for these environments.
Today, the PurAire range spans 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 products….
Our fixed room and HVAC systems support continuous occupied-space applications, with UL 2998 zero-ozone certification applying to specific models.
The important lesson is the distinction between technologies. Professional ozone treatment and bipolar ionisation serve different purposes. Equipment selection must account for the application, occupancy and model-specific requirements.
PurAire broadened our capabilities, while reinforcing the philosophy established in our earliest projects: the right technology depends on the specific facility and the problem.
Measuring What Matters
Our work has also expanded into indoor air quality monitoring.
An odour complaint may be obvious. Other concerns need measurement to understand them. Depending on the instrument and sensor configuration, monitoring can provide information about particles, carbon dioxide, volatile organic compounds, temperature, humidity or specific gases.
Our monitoring portfolio includes Atmocube, Kaiterra, Aeroqual and EcoSensors instruments, selected according to the parameters and application involved.
We start by understanding the site. Where measurement is needed, we use it to help identify the problem and assess the result of corrective action.
Our wider portfolio now also includes RestorAir room-recovery equipment, Novita Air Purifiers and Dehumidifiers, kitchen-exhaust treatment, and systems for aquatic life support and industrial water treatment. We represent three of the most well-known and established brands in this field: AZCO Industries, ClearWater Tech and Absolute Ozone.
There is no single device or product that solves every indoor air quality problem or aquatic life support need..
What Twenty Years in Real Buildings Has Taught Us
Experience is built after the quotation is accepted and the equipment is installed.
A system has to suit the hotel guest room, the building, its airflow, its operating conditions and the people maintaining it. A hotel room, a hospital area and a manufacturing floor each place different demands on the solution.
Twenty years has taught us four practical lessons.
- 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 the occupied environment. - 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.
That is the value of an operating history: experience in selecting, installing and supporting equipment in working facilities, and learning from what happens after installation.
It has made us increasingly solutions-led. Sometimes customers need treatment equipment. Sometimes they need a different maintenance approach, better ventilation or further investigation before any purchase makes sense.
Our role is to help them identify the appropriate next step.
The Technology Kept Changing. The Idea Never Moved.
The technology kept changing. Ozone generators for the stubborn odours ordinary cleaning could not shift. Then ozonated water, helping reduce reliance on conventional cleaning chemicals. Then our own PurAire bipolar ionisation, including fixed systems for the spaces you cannot take offline. And today, real-time air quality monitoring and advanced oxidation.
Our portfolio brings these complementary 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
Four generations of technology. One idea that never moved.
Understand the problem. Choose the right solution. Make it practical for the building and the people who operate it.
But adding technology is only useful when it improves the options available to our customers. We consider the application, the practical demands of operation and maintenance, and the testing or certification relevant to the particular product. Where results are measured, the test conditions and limitations matter as much as the headline number.
Our aim remains the same: cleaner indoor environments for guests, patients, staff and students, and practical solutions for the teams responsible for those spaces.
THANK YOU FOR TWENTY WONDERFUL YEARS….
Behind every stage of this journey are people: our team, our technology partners and the customers who trusted us with their buildings.
To the engineers, executive housekeepers, facilities managers, hospital teams, building owners, consultants, contractors, distributors and suppliers who have worked with us: thank you. You gave a small Singapore company the opportunity to grow. You brought us difficult questions, challenged us to improve and helped shape the business we are today.
Twenty years ago, we were two people and an idea. Today, we bring two decades of experience to the next problem — and we are still learning, evolving and looking for better answers.
2006–2026. Twenty years of practical environmental solutions.
