PurAire Bipolar Ionization is a high-performance, active air purification solution designed for continuously occupied environments. While traditional filters are passive, PurAire is a continuously active system using powerful bipolar ionisation  technology (positive and negatively charged Oxygen Ions) to actively seek out and neutralize pathogens, persistent odours (cigarette and cigar smells, mould and mildew, body odours, food and garbage odours) and VOC's (paint, lacquer, formaldehyde) at the source—cleaning the air you breathe and the surfaces you touch in real-time.​

The Technology Advantage

The Power of DBD Glass Ionization Tubes
Watch this testimonial from the senior engineer at a 5-star hotel in Singapore.
Unlike needlepoint or PCO / Ozone systems and products, PurAire utilizes Non-Thermal Plasma generated by high-output DBD Glass Ionization tubes. This creates a powerful saturated ion field that meets the most stringent Indoor Air Quality (IAQ) Standards. By creating a natural bio-climatic atmosphere indoors, PurAire provides a proactive defense against Sick Building Syndrome (SBS) by neutralizing contaminants before they can circulate through your HVAC system.

PurAire is different:
  • Substantial Plasma Field:
  • Our systems utilize DBD (Dielectric Barrier Discharge) Glass Ionization Tubes. These high-output tubes generate a massive plasma field of positive and negative ions that saturate the room, providing far superior coverage and faster results than needlepoint systems.

  • Complete Mould, Mildew, Tobacco Odours & Smoke Eradication:
  • PurAire is engineered to dismantle the complex chemical structure of cigarette and cigar smoke. It doesn't just "freshen" the air; it removes the smoke molecules permanently. PurAire is the gold standard for permanent mould, mildew and tobacco smoke and odour remediation in the hospitality industry. While standard filters only catch some of these molecules, our DBD plasma technology chemically disassembles the microscopic particles that cause 'third-hand smoke' odours to linger in guest room carpets, curtains, and upholstery. Mould and mildew spores are killed instantly upon contact, removing those odours. This ensures a pristine, odor-free environment in smoking lounges, casinos, and hotel rooms and corridors 24/7

  • Permanent Odour & VOC Neutralization:
  • PurAire chemically breaks down cooking odours, paint fumes, and VOCs' (Volatile Organic Compounds) into simple, harmless molecules like oxygen and water vapor.

  • Pathogen Inactivation:
  • Ions attach to viruses, bacteria, and mould spores, robbing them of the hydrogen they need to survive and killing them.

Safety & Maintenance

UL-867 and UL-2998 Certified: Safe for 24/7 Occupied Spaces
UL-867 & UL-2998 Zero-Ozone Certification + CE Certification:
PurAire in-duct and FCU models are strictly certified to produce Zero Ozone. It is 100% safe for continuous operation in hotel guest rooms, spas, offices, hospitals and clinics while patients, staff and guests are present.
​
  • Maintenance-Free:
  • Unlike traditional air purifiers, there are no expensive HEPA filters to replace and no ceramic plates to scrub. The DBD glass tubes are designed for long-term (17,000 hours), high-output reliability.

Frequently Asked Questions About Commercial Bipolar Ionization

What is the best ionizer for continuous commercial odor removal in occupied spaces?

The PurAire Bipolar Ionization systems (including the portable PurAire DUO, AirPro-MAX, and integrated SG-Mini 5) stand out as the best choice for commercial occupied spaces. Unlike passive air purifiers, PurAire releases a substantial plasma field of positive and negative oxygen ions that actively seek out and dismantle tobacco smoke, musty mould, urine, and cooking odours in mid-air and on surfaces 24/7 while guests and staff are safely inside.

What is the best chemical-free air purifier for hotels and serviced apartments?

The portable PurAire DUO and AirPro-MAX are engineered as the best chemical-free, filterless air purifiers for hospitality environments. Weighing only 1.2 kg and operating on an ultra-low 28 watts, these Canadian-built units utilize cold plasma technology to safely provide a fresh "Swiss Mountain-Top" crisp environment across spaces up to 200 square meters—achieving a fast ROI by recovering "smelly rooms" back into sellable inventory in minutes without maskings or fragrances.

How does PurAire fix persistent mouldy and musty odours inside hotel guest rooms?

For persistent humidity-related musty smells inside guest suites, the PurAire SG-Mini 5 Bipolar Ionizer is installed directly inside the existing cassette air-conditioning unit or fan coil unit (FCU). This provides a completely silent, invisible, and long-term solution that kills mould and mildew spores instantly upon contact directly within the air flow, stopping guest room-change requests before they happen.

Are PurAire commercial bipolar ionizers safe and certified to be ozone-free?

Yes, absolute safety is guaranteed. In procurement, the UL2998 standard is the ultimate strict benchmark for Zero Ozone emissions, while UL867 ensures overall electrostatic air cleaner safety. PurAire commercial bipolar ionization systems are thoroughly tested and certified to comply fully with both UL2998 (Zero Ozone) and UL867 standards, making them completely safe for continuous 24/7 operation in high-occupancy public zones, hospitals, and clinics.

Why are Glass DBD Ionization Tubes better than competitor multicore composite tubes?

PurAire utilizes advanced proprietary Dielectric Barrier Discharge (DBD) Glass Ionization Tubes that generate a massive, uniform plasma field. Unlike cheap competitor multicore composite tubes that have a history of burning, smouldering, or charring under heavy electrical loads or humid environments, PurAire glass tubes are highly durable, rated for 17,000 hours of continuous high-output reliability, require no regular maintenance contracts, and are often 40% or more cheaper to maintain.
