Create a safe workspace with the PureAir R150 professional air cleaner. It is now widely accepted that COVID-19 is transmitted in enclosed indoor spaces. Businesses, especially those managing quaratine hotels, must therefore start seriously considering more effective ways to improve indoor air quality (IAQ) to provide a clean, safe working environment and peace of mind for both staff and customers.
Safe air should be an integral part of a coronavirus precautionary strategy as viruses have been proven to attach themselves to airborne pollutants which leads to them remaining suspended in breathable air for up to 3 hours and able to travel further distances.
In a recent COVID-19 guidance document by REHVA 1 (the Representatives of European Heating and Ventilation Associations) they highlighted that, “analyses of superspreading events have shown that closed environments with minimal ventilation have strongly contributed to a characteristically high number of secondary infections of coronavirus.” In addition is has been found that “… a long-range airborne transmission mechanism implies that keeping a 1-2 m distance from an infected person isn’t enough, and that concentration control with ventilation is needed for effective removal of particles in indoor spaces.”
With the PureAir R150 from Alert Technology 99.43% of harmful airborne particles are eliminated. The PureAir’s multi-stage sanitising process uses a superior industrial HEPA-14 filter (10x better than HEPA 13), medically proven UV-C light sterilization to kill the DNA and RNA of viruses and a greater air flow than other air cleaners on the market to effectively changes the air in a room of 150m3 up to 7 times per hour - providing your staff and customers clean, safe, virus-free air.
The PureAirR150 unit filters out airborne pollutants such as dust, allergens, aerosols, moulds, and VOCs (volatile organic compounds), and its UVC light sterilisation kills airborne bacteria and viruses, including COVID-19. It is also effective at removing strong odours with the addition of an optional extra carbon filter.
A recent clinical study2 conducted in Germany, testing the efficiency of a R150 room air purifier on the reduction and inactivation of airborne viruses, concluded that the recovery of active viruses was reduced by 99.43 % after 45 minutes of device operation.
The study outlined: (an excerpt shown below)
‘Since the room air cleaner is based on the principle of filtration as well as inactivation of viruses, the magnitude of the reduction was determined.
Table 2 shows the reduction of recovery of active viruses analysed in the laboratory in relation to the measurement P1 (reference measurement, without the influence of the device) with continuous dosing of viruses. In addition to the effect of the device, the natural loss of activity in the suspension as a function of time also influences recovery. The virus titer (pfu/mL) of the suspension was therefore additionally tested at the beginning and end of the experiment. No significant loss of activity took place in the suspension.’

Currently, poor indoor air quality is one of the largest environmental, health and wellbeing risks faced by building occupiers. According to the World Health Organisation, general air pollution causes over 3 million deaths globally every year.
Air purification is already widely adopted within the healthcare sector. The wider implementation of air filtration and purification across all sectors will help reduce risk, demonstrating that the duty of care to provide a safe environment for people to live and work in a post lockdown world is being fulfilled.
