Airius PureAir: Essential Virus Protection For Dentists


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.

They had researched other air purification systems, but they did not clean surfaces or offer continuous instant protection against contaminants brought in to the Surgery.



Our Sales and Support Team worked closely with the Surgery to design an Air Purification Solution that met their needs. Incorporating the latest technology, the Airius PureAir Series was specified for installation in each of their Dental Theatres and patient waiting room.

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.


Since installation Harewood Dental Surgery have reopened and the results have been fantastic. Not only are the staff happy that they are protected with the latest in air purification technology, but patients are also reassured by the fresh purifying aroma from the PureAir system’s active cleaning agents in the air:

  • •  Kills up to 99.99% Viruses, Germs & Bacteria
  • •  Cleans both the Air & Surfaces
  • •  Purifies all air in the space at the same time
  • •  Instantly attacks new contaminants brought in
  • •  No filters required
  • •  Eliminates unpleasant chemical Odours & VOCs

PureAir Technology Explained

How does the PureAir Series PHI Cell kill bacteria and viruses in the air and on surfaces?

The PureAir Photohydroionisation (PHI) Cell, manufactured by RGF Environmental, one of the worlds leading specialists in air, water and food purification, is a kind of UV light that emits advanced oxidation plasma. Included as part of a fan system, the PHI cell distributes hydro-peroxides, superoxide ions and hydroxide ions throughout the space, neutralising 99% of micro-organisms in the air and on surfaces.

PHI cells produce a group of oxidants known as hydroperoxides. Far from new to our world, hydroperoxides have been around for 3.5 billion years – and today they are commonly used in food processing environments, where they offer an anti-microbial treatment without leaving chemical residues.
