The Power of UVC and HEPA Technology to Deliver Clean, Sterilised Air
Because they are enclosed, usually poorly ventilated spaces, elevators are one of the most hazardous environments for viral contamination spread. Many companies have limited the number of occupants, to reduce the risk of infection. However, as people move from home working, back in to the workplace, many facilities managers and employers appreciate that reduced occupancy is not a viable long-term solution.
Our React-Air Ascend is designed to be fitted to the top of a commercial elevator car and contains our React-Air Destroyer Array – a commercial pathogen neutraliser. Air from the car is drawn upwards in to the React-Air Ascend and then passed through the Destroyer Array.
The 3 Stage Process for Eliminating Covid-19
1. HEPA 13 Filtration
Using the React-Air’s high-pressure fan, air is passed through a HEPA 13 filter to remove 80% of particles 0.3-1 microns. This process removes pollens, bacteria and viruses bonded to larger particles such as water droplets (the primary way Covid-19 spreads through airborne transmission).
2. Powerful UV Array
The filtered air is then passed through a UVC array, which delivers a dose of 250J/M3 – enough to neutralise Covid-19 (67J/M3 for one second of exposure according to studies). The effect of the UVC Array is intensified by its polished aluminium interior. UVC renders virus particles inert (sterile) by changing the molecular structure of the virus DNA.
3. Activated Carbon Filter
Finally, the air is passed through an activated carbon filter to remove any remaining odours. As well as removing any natural odours in the environment, the reaction between UVC and dust particles creates a mild, but for many people, unpleasant smell – all are removed with Activated Carbon.

Our products have been tested and proven effective against Covid-19
Our React-Air Technology has been tested by CDC approved laboratories in the United States for their effectiveness against removing and neutralising airborne (aerosolised) Covid-19 from the air. In multiple trials, our 'Destroyer' technology proved a 89% neutralisation rate of Covid-19 under test conditions, within 15 minutes of operation.
Trials were undertaken by introducing airborne (aerosolised) Covid-19 in to a sealed test-environment. After a number of control tests (without our technology) and full tests (with our technology), airborne Covid-19 was found to be reduced from 27% of average control test degradation to 89% with our React-Air Technology in place, within 15 minutes.
Studies by The University of Boston undertaken in 2020 have shown that Covid-19 is highly susceptible to UVC light. Japanese scientists have been conducting studies on the effects of ozone in neutralising Covid-19 on surfaces and have shown it to be highly effective with a 90% sterilisation rate. 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. This is however, a calculation and currently is not backed up by laboratory tests.
