Bipolar ionisation

Featuring the latest in needlepoint bipolar ionization (NPBITM) technology from one of the world’s leading manufacturers of indoor air quality systems – Global Plasma Solutions – the PureAir+ NPBI Series uses the power of ions to provide continuous round-the-clock sterilisation, neutralising up to 99.9%+ of all known pathogens, VOCs and odours, in both the air and on surfaces.

The PureAir+ NPBI also provides all the features and benefits of the world’s most popular destratification and airflow circulation fans from Airius. These fans help to balance temperatures, improve comfort, reduce heating and cooling costs, and cut carbon emissions.

Cleans The Air & Surfaces

Similar to the PureAir PHI, the PureAir+ NPBI Series provides both surface and airborne protection.

PureAir+NPBI circulates natural cleaning ions around your environment. The ions charge draws them to contaminants such as viruses, germs, VOCs or odours. When the ions bond they react, neutralising the contaminant, rendering it inert, safe and odour free.

This combination of industry leading NPBITM purification technology, paired with Airius’ patented columnar laminar airflow circulation, enables the PureAir+ NPBI Series to circulate its natural cleaning ions throughout spaces more effectively than any competing purification fan manufacturer.

The science explained

At the heart of each PureAirNPBI fan unit is the needlepoint bipolar ionisation (NPBITM) technology that provides the highest level or air and surface purification. By using the power of ions, the PureAirNPBI Series is able to clean spaces in the same way the Mother Nature cleans our outside air.

The integrated NPBITM system features two separate emitter points, comprising hundreds of tiny carbon strands, similar to a brush head.

During operation, an electric charge is passed through the strands.  This creates a plasma field through which each point emits a high concentration of ions. Separate emitters release positive and negative ions.

Ions are then circulated into the air via the fan, where they can protect against pathogens, particles, VOCs and odours.


Ozone can be found all around us at both work and home, produced by a wide variety of equipment and substances such as printers, lights, televisions, dishwashers and cleaning chemicals, to name a few.  But as with all things, extremely high levels can be harmful.

Airius product ranges are tested to meet and exceed all safety and quality standards, including ozone. But due to its unique design, the integrated NPBITM system within the PureAir+ NPBI also meets the new UL 2998 product standard, one of the highest ozone standards possible. This classifies the PureAirNPBI Series as an ‘ozone free’ product.

HVAC savings

Not only does the PureAirNPBI Series provide all the benefits of safe, clean, germ and odour free air, but customers also benefit from the wide range of advantages provided by the world’s most popular destratification fan.


Improved comfort and environment control, reduced energy costs for heating and cooling, a reduction in carbon footprints and CO2, are just some of the many benefits from installing an Airius Destratification Fan system. See here for full benefits of Airius Destratification Fans.

Installation Services

Airius Electrical can install and optimise your Airius PureAir Pearl Series fans. With more than 30 years of experience, we understand how to safely and securely install your air purification and destratification fans.

With our own fleet of access equipment, the Airius Electrical team are available to rapidly install your fans. And because we have a close partnership with the Airius team, we understand precisely how to install their products to achieve the greatest impact.


The GPS NPBITM technology incorporated within the PureAir+ NPBI Series is one of the first to have been tested on a live strain of SARS-CoV-2 and not a surrogate or similar virus.

The testing was carried out by ‘Aviation Clean Air’ in a real world environment against the SARS-CoV-2 virus (COVID-19), which showed an inactivation rate of 84.2% within 10 minutes, 92.6% within 15 minutes, 99.9% within 30 minutes.

It is important to note that no medical claims are made.

24/7 air care

Using the same natural method Mother Natures uses to clean our air, the PureAir Pearl Series circulates positive and negative ions throughout spaces via the fan to provide pathogen neutralisation, particle reduction and odour elimination in any type of indoor environment.

The polarity of the ions attracts them to all particles within the space, causing the particles to cluster together and make them filterable. They also bond with and neutralise pathogens, VOCs and odours by removing them of a hydrogen atom, breaking them down into their basic, harmless and odourless compounds, such as O2, CO2, N2 and H2O.

As these ions are being continuously circulated into the space, The PureAir Pearl Series is providing round-the-clock 24/7 protection, helping to maintain a clean, safe and fresh environment within your building.

Reduce mould, odours, VOCs

Unpleasant odours can have a significant impact on spaces, whilst mould and VOCs can have serious visual and health implications.In commercial spaces this can have a detrimental effect on your bottom line.

The PureAir Pearl Series with its integrated BiPolar purification system emits charged ions into the air.These ions bond with odour, mould and VOC particles, breaking them down into their basic, harmless compounds such as O2, CO2, N2 and H2O.This reduces or eliminates VOCs, gases, vapours, mould and mould spores, whilst leaving environments smelling fresh and odour free.


The PureAirNPBI Series requires no maintenance, helping to make managing buildings and purification systems as simple and cost effective as possible.  Not only are the fan motor and bearings sealed within the unit housing, but the needlepoint bipolar ionization (NBPI) purification system is also self cleaning, meaning that once installed you’ll have one less thing to worry about, saving you and your business both time and money.

The NPBITM auto cleaning system works by using a small revolving arm that spins intermittently, brushing dust and particles from the carbon emitter strands. This ensures your PureAirNPBI unit continues to work effectively year after year, supported by Airius’ leading 5 year warranty.

Reduce fresh air demand

To maintain optimum air quality requires regular circulation of fresh, outside air being brought into the building to dilute, disperse and replace stale, used, dirty air. Cycling the HVAC system requires a great deal of energy, and dramatically increases running costs.

By installing an Airius PureAirNPBI system in your building, you can reduce the requirement for outdoor air intake by up to 75%, totalling a saving of approximately 30% on your energy costs. It also helps maintain your HVAC system by keeping coils clean without an expensive UV system, reducing pressure loss.

For ceilings up to 10m

PureAirSeries standalone fans are ideal for any space with a ceiling up to 10m high, where there is a need to clean air, sterilise surfaces and eliminate odours. This makes them suited for a wide range of environments, including hospitals, care homes, public spaces, offices, factories, schools and many more.

For spaces with higher ceilings, the PureAirNPBI Series can be used in conjunction with the Airius range of airflow circulation and destratification fans, to increase coverage and further circulate its charged ion cleaning agents throughout larger spaces.

Airius engineers can help you select the correct quantity of PureAirNPBI Series fans to service your facility with clean, odour-free air, as well as balance temperatures and humidity to improve comfort and reduce energy costs.
