Testimonials - Built on Long-Term Customer Relationships
What our customers tell us, in their own words.
“I have worked with the ProMedUSA team for over sixteen years. Their equipment remains the gold standard for hospitality air quality. We recently integrated their PurAire Bipolar Ionisers, and the results have been outstanding.”
“PurAire’s portable ionisers help my staff to quickly remove odours from our guest rooms. We can now, clean and deodorise and put these rooms back into inventory within 30 minutes or less. The PurAire-DUO has paid for itself in less than a week.”
“We were very skeptical if this would really work. We have a lot of guests who smoke in our non-smoking rooms. We also have a number of problem rooms which constantly smell mouldy and mildewy. We installed PurAire in several of these rooms as a trial, and within hours, the smoke smell was gone. Mould and mildew took a bit longer, but now all our trial rooms are up to our 5-Star standards. We now use the PurAire-DUO for portable daily use, and our engineers have installed PurAire units in 15 guest room FCU’s with great success and are budgeting to install more units in the balance of our rooms next quarter.”
“For our discerning clients and patrons, we need to keep all of our private dining rooms smelling fresh, clean and inviting. We have tested many products and technologies to help us achieve that goal, but the only one that performs up to our standards of excellence are the PurAire Bipolar Ionisers. James, one of our staff remarked: “After using the ioniser the food smells are totally gone and don’t linger. Truly a great product! I would highly recommend PurAire Ionisers to anyone or any business who has odour issues in their premises.”
- How It Works
Simple Steps to Transforming Your Indoor Air
PurAire’s UL2998-certified Glass DBD (Dielectric Barrier Discharge) technology generates billions of positive and negative oxygen ions through a safe, ozone-free cold plasma discharge. These ions disperse through the space, attaching to mould spores, bacteria, viruses and odour molecules — killing pathogens at the source, oxidising VOCs into harmless CO₂ and water vapour, and breaking down odours at the molecular level. Independent lab tests show up to 90% VOC reduction, >95% mould spore reduction, and 99%+ microorganism deactivation.

Frequently Asked Questions
PurAire releases billions of positive and negative oxygen ions that surround odour molecules — smoke, urine, VOCs, mould — and break their chemical bonds through oxidation, neutralising them instead of masking them.
Yes. Our Cold Plasma DBD technology is UL2998 certified for zero-ozone emissions and uses no chemicals or sprays — safe for 24/7 use in occupied homes, clinics and hotel rooms.
HEPA is passive — it only cleans air pulled through its filter, often leaving odours trapped in carpets and corners. PurAire is active, sending ions into the entire space, with no filter replacements (Glass DBD tubes last up to 17,000 hours).
Yes. Ions penetrate fabric, carpets and HVAC systems to eliminate mould and mildew at the source. Real Singapore installations in hotels, apartments and clinics show visible reduction and fresher air within days.
Portable units (DUO, AirPro-MAX) for quick spot treatment; wall-mounted and lift units (MiniPro, LiftPro) for public areas; in-duct/FCU models (FCU/2, FCU/3, SG-BPI series, SG-MINI-5A) for HVAC integration; and the Ultra Series for large venues up to 1,200+ m². All use Glass DBD tubes rated up to 17,000 hours.
Odours disappear, mould/mildew is reduced, and 99%+ of viruses and germs are deactivated — with no filters to replace and lower energy use from smart airflow switches.
Yes — ions break down odour molecules from cigarette smoke, food, urine, paint, adhesives and new-furniture VOCs at the molecular level, typically within a few hours.
Yes — beyond odour control, ions deactivate viruses and bacteria on contact, and cluster PM2.5 and haze particles out of the air for a clearer breathing environment.
