The React-Air Impact is a standalone air and surface steriliser designed for use in commercial environments. Using a UVC technology, the powerful fans drive the airflow through the decontamination chamber, neutralising bacteria, viruses, pollen and odours, delivering clean and sterile air to a room. The Impact is also a powerful ozone generator, which can be set to activate when a room is unoccupied, filling the environment with ozone gas. When the ozone comes in to contact with items and surfaces, it eradicates viruses and bacteria, sterilising everything it touches.
Multiple Impacts are connected via WiFi or 4g, to allow you to manage the settings on all devices through a single unit or through our desktop and mobile app. Real-time and historic data on airfl ow, air quality, and ozone sterilisation can also be viewed on our desktop and mobile applications. Ozone Release, UVC Times can be set using the UVC touchscreen. The Impact also contains a powerful sensor array that monitors Air Exchanges, Air Quality and UVC Dose. This information is displayed on the screen to give users extra peace of mind.
UVC light is highly effective at decontamination because it destroys the molecular bonds that hold together the DNA of viruses and bacteria. UVC light has been regularly used to decontaminate surgical tools and hospital rooms.
The Impact draws air into its extraction vents which are specifically located at shoulder height, so as to capture as many virus particles as possible. The air then passes through a medical-grade HEPA 13 filter, trapping any larger contaminants, and finally through a
high intensity UVC chamber, capable of delivering a dose of over 240J/M3 – enough to neutralise even the most resilient coronaviruses studied.
The high power, variable fan can circulate up to 1504 metres cubed of air per hour – enough to give 9 air cycles per hour in an average 50 person office space.
Viruses and bacteria can be neutralised with alcohol and hydrogen peroxide, however, these substances cannot be used on some surfaces, and will only be effective on items and surfaces which can be reached. Ozone gas will penetrate hard to reach areas, fabrics and rough or uneven surfaces. This makes ozone gas a valuable addition to standard cleaning and disinfection practices.
The Impact contains 2 high powered ozone discharge plates which operate as a separate function from the air cleaning UVC technology.
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.
Ozone can be harmful if inhaled so the Impact can be set, by an authorised user with a password, to be released when the room is empty. This can be set on a timer function and an audible and visual warning is given before ozone is dispersed, with an emergency shut-off feature, should anyone still be in the room. Once the ozone cycle is complete, the Impact switches back to UVC mode to eliminate any trace ozone, faster than its natural half-life conversion back to oxygen.
The touchscreen control of the Impact can be used to set fan speed, UVC dose and adjusted to neutralise diff erent types of bacteria and viruses from the air. But the Impact also contains a complex sensor array that actively monitors Air Quality (AQI) and air exchanges within the room it is placed. This information is synced wirelessly with our cloud platform so that information is always available to building managers, across multiple units and multiple sites.
The touchscreen can also be set to display this data. This is highly eff ective for creating peace of mind for building occupants, delivering air cleaning that can actually be seen in real-time, on each Impact unit. The data is available through our React-Air mobile app and on our online web-based app, delivering confi dence that you are meeting your duty of care.
The React-Air monitoring system uses state-of-the-art measurement contained within the Impact device. Measurements are taken every 10 seconds to ascertain:
Lamp Function and Brightness
Over time, all UV Germicidal Lamps will lose brightness and the surfaces become contaminated by impurities in the air. Once this reaches a threshold, the in-built UV monitor alerts the user that a service is required.
Air Quality
The integrated air quality monitor measures air impurities down to 0.1um. Every 10 seconds, this information is recorded and sent back to the building’s base unit to show real-time air quality information.
Air Flow and Air Exchange Rates
By constantly monitoring air-flow volume through each one of the Impact units, the React-Air system calculates the number of hourly, daily, and weekly air exchanges in your building.
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.
