PureAir PHI Active Cleaning

‘Active’ cleaning uses systems that circulate purifying agents in and around the environment cleaning the whole space at the same time, whereas ‘Passive’ cleaning requires air to go through a filter to be cleaned.

Clean all the air and surfaces in your home or business at the same time without the need for air to pass through a filter. By circulating active cleaning agents into spaces from the PureAir’s integrated PHI Cell manufactured by RGF Environmental, one of the worlds leading air, water and food purification specialists, harmful viruses, pathogens and contaminants are destroyed and rendered inert and safe providing continuous 24/7 protection. Even if new contaminants enter the space the active cleaning agents immediately attack and eliminate them, even if they are transferred to surfaces. With a filter based system it may take hours to process all the air in a room, especially if new contaminants are brought in.  They also provide no protection against contamination.

Passive Air Purification

Graphic Showing Coverage Limitations of Passive Air Purification Systems

Passive air purification systems require air to pass through a filter in order to be cleaned. This means it can take a very long time to treat all the air in a room or space, which may not even be achievable in poorly circulated areas.

Active Air Purification

Graphic Showing How The Active Purification System in the Airius PureAir PHI Destratification Fan & Air Purification System Provides Complete Internal Coverage

The PureAir PHI’s Active air purification system does not require air to pass through the unit, but instead sends purifying agents from its integrated PHI Cell out into the space via the fan, not only cleaning the air, but all surfaces they come into contact with as well, all at the same time.

How It Works

The Airius PureAir PHI Series incorporates a patented PHI (Photohydroionisation) Cell within the fan unit. The PHI Cell emits ‘Ionised Hydroperoxides’, a naturally occurring cleaning agent, which are circulated throughout spaces via the fan.

As the fans circulate internal atmosphere, the PHI circulates its neutralising Ionised Hydroperoxides, providing 24/7 continuous Air Purification.

Airius PureAir PHI Destratification Fan Air Purification Fan System - How It Works Cross Section


The Airius PureAir’s Integrated PHI Cell™ Manufactured by one of the Worlds Leading Specialists in Air, Water & Food Purification – RGF Environmental, is the latest advancement in Photohydroionisation™ Technology, using an Advanced Oxidisation Process to clean air and eliminate odours

At the heart of every PureAir Series fan is a unique Photohydroionisation (PHI) Cell, which uses a broad spectrum, high efficiency UV bulb working with a hydrated quad-metallic target. This acts as a catalyst for a reaction that produces hydroperoxides, super oxide ions, passive negative ions, hydroxides and ozonide ions. These safe and naturally occurring ions and oxides are circulated throughout spaces via the fan, which bond with germs, bacteria and viruses and through an advanced oxidisation process breaks them down, rendering them inert, safe and odour free. In addition to biological pollutants these cleaning agents also neutralize chemicals such as mercury, benzene, formaldehyde, chloroform, and ammonia.

Case Studies

Tandara Lodge Community Centre protects its residents and guests with the Airius PureAir PHI Destratification Fan and Air Purification System

Tandara Lodge Community Care

Tandara Lodge operates a 46 bed (high and low care) Residential Aged Care Facility for permanent, respite and palliative residents. Managers were keen to find ways to reduce the annual occurrence of influenza outbreaks and protect their residents from seasonal diseases and contacted Airius.

Since installation of the PureAir System in their facilities they have had 0 notifiable outbreaks in 5 years since implementation and saved £1,000’s on outbreak containment and clean-up.

The Harewood Dental Practice protects its patients with the Airius PureAir PHI Destratification Fan and Air Purification System

Harewood Dental Practice

In response to the COVID19 Pandemic Harewood Dental Surgery needed to find a solution to help provide protection and reassurance for their staff and patients against the threat of infection from Coronavirus and other harmful pathogens.

The units were simple to install over the course of 1 day and now provide the client with safe, clean air, eliminating up to 99.99% of all harmful Viruses, Germs & Bacteria.

Technical Data Chart for the Airius PureAir PHI Destratification and Air Purification Fan Range


Typically, Airius fans are installed in the ceiling space with the nozzle directed directly downwards and performs best when the air column is unimpeded to the floor.

Units must be hung using fixings such as hooks, chains, cables etc to professionally installed hardware capable of supporting a minimum of five times the weight of the unit.

Does the PureAir PHI eliminate COVID19?

In independent tests RGF PHI Cell technology was shown to have a 99.9% inactivation rate on surface and 99.5% inactivation rate on aerosol forms of the SARS-CoV-2 (COVID19) virus.

Testing commenced in March carried out in a 36m3 (1,280ft3) testing chamber using the SARS-CoV-2 virus, not a surrogate or similar virus. Results show the virus is killed on contact with the PHI’s cleaning agents, effectively neutralising the virus within the chamber within a matter of minutes.

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

What is the difference between 'Active' & 'Passive' Air Purification?

There are two types of air purifiers available for home use, which use two main kinds of purification processes. These are:

• Passive type air purifiers, which are the standard HEPA filters, where the air is drawn into the machine and passed through a filter to remove contaminants, before clean air is released on the other side.

• Active type air purifiers, that send cleaning agents out into the space to clean the air, and create an ambient atmosphere.

What is Photohydroionisation?

Photohydroionisation (PHI) is an advanced oxidation technology developed to minimize and neutralize indoor air pollutants such as bacteria, viruses, mould, gases (VOCs) and odours.

PHI utilizes a broad-spectrum, high intensity UV light targeted on a hydrated quad-metallic catalyst surface. This target surface is covered with a proprietary quad-metallic and hydrophilic coating. The UV light reacts with the catalyst and moisture to produce an advanced oxidation plasma consisting of hydro-peroxides, super oxide ions and hydroxide ions.

These friendly oxidizers will revert back to oxygen and hydrogen once they’ve come in contact with and eliminated the pollutant. Find out more about Photohydroionisation here.

What are ionised Hydro Peroxides?

Controlled oxidation (giving up or losing of an electron) is an excellent way to destroy organics such as odours, viruses, moulds, bacteria and VOCs.

The PureAir Series emits ‘friendly’ oxidisers, meaning they revert to harmless oxygen, water and hydrogen.

Hydrogen peroxide has been used by the medical community for 170 years and is considered the safest oxidizer available (after oxygen). It is widely used today in toothpaste, mouthwash and household cleaners.

Hydroperoxides are known as Mother Nature’s natural cleaning agent. It is ionized hydrogen peroxides that make the air smell clean after a thunderstorm.

What is the Warranty period?

All Airius PureAir Series fans come with a 5 year Fan Replacement Warranty, as well as a 1 year PHI Cell Replacement Warranty. Simply return defective units to Airius, carriage paid and upon receipt Airius will dispatch a new unit by return carriage fully paid.
