The Clean Air Solution for Today’s Changing World

The React-Air One, is a portable air sanitiser, designed for use in hospital and care environments. Using a unique UV-C light array, the powerful fans drive the airflow through the decontamination chamber, neutralising bacteria, viruses, pollen and odours, delivering clean and sterile air to a room.  Unlike ozone generators, it can be used whilst people remain in the room and generates no harmful gasses and at a fraction of the price of leading portable ozone generators..  When used in conjunction with normal cleaning techniques, it is a highly effective in the fight against bacteria and viruses.

UV-C technology has been used for many years to sterilise hospitals, operating theatres and surgical instruments.

 

When placed in a room with an airborne viral or bacterial risk, the RA1 circulates the air up to 30 times per hour.
It’s quiet operation, portable design and high-powered UV-C technology is the perfect combination for intermittent or constant use within a care environment.

How Can the React-Air One Help Beat Viruses?

The three main types of UV rays are UVA, UVB, and UVC. Because UV-C rays have the shortest wavelength, and therefore highest energy, they are capable of killing bacteria and viruses, also called pathogens.  UVC light has a wavelength of between 200 and 400 nanometers (nm). It is highly effective at decontamination because it destroys the molecular bonds that hold together the DNA of viruses and bacteria, including "superbugs" which have developed a stronger resistance to antibiotics.

Powerful UV-C light has been regularly used to decontaminate surgical tools and hospital rooms. A study that included 21,000 patients (1) who stayed overnight in a room where someone had been previously treated found that sanitising a hospital room with UV-C light in addition to traditional methods of cleaning cut transmission of drug-resistant bacteria by 30%. This is partly because UVC light can effectively sanitise hard-to-clean nooks and crannies. UV-C light also works by destroying the DNA of pathogens, which makes it effective against "superbugs."

How effective are our React-Air products against coronavirus?

Since coronavirus (covid-19) is a new virus, there have been few specific studies.  However, scientists have been studying the susceptibility of Coronaviruses to UV-C light for over 30 years.  This information, published by research.net shows the results and effective dosages of UV-C light required to inactivate various strains of coronavirus.

“Table 1 above summarises the results of studies that have been performed on Coronaviruses under ultraviolet light exposure, with the specific species indicated in each case. The D90 value indicates the ultraviolet dose for 90% inactivation.

Although there is a wide range of variation in the D90 values, this is typical of laboratory studies on ultraviolet susceptibility. The range of D90 values for coronaviruses is 7-241 J/m2 the mean of which is 67 J/m2, should adequately represent the ultraviolet susceptibility of the SARS-CoV-2 (COVID-19) virus.”

By using this exposure data, and comparing the UV light irradiance measurements from our products, we calculate the exposure times required to deactivate coronaviruses.
