The Power of UVC and HEPA Technology to Deliver Clean, Sterilised Air

Our unique Induct system combines powerful pathogen-neutralising UV-C germicidal technology with measurement data and tools that ensures the air you breathe is protected from bacteria and virus risk.

The React-Air Induct system uses Pure Germicidal Light, HEPA 13 Filters and includes four High-Intensity Pure Fused Quartz UVC Germicidal Lamps which allow air to flow through them, destroying biological contaminants, preventing them from growing again and spreading.

The 3 Stage Process for Eliminating Covid-19

1. HEPA 13 Filtration

Utilising 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 binded to larger particles such as water droplets (the primary way Covid-19 spreads through airborne transmission).

2. Powerful UV Array

After this, the filtered air is passed into a UVC array, which delivers a dose of 250J/M3 – neutralising Covid-19 (67J/M3 for one second of exposure according to studies). The effect of the UVC Array is compounded by the polished aluminium interior. By changing the molecular structure of the virus DNA, UVC renders virus particles inert (sterile).

3. Activated Carbon Filter

To remove any remaining odours the air is passed through an activated carbon filter. In addition to removing any natural odours in the environment, the reaction between UVC and dust particles creates a mild, but for some, unpleasant smell – all are removed with Activated Carbon.

Real-Time data on our mobile app and online, for monitoring across multiple sites

The React-Air monitoring system uses state-of-the-art measurement contained within the Induct device. Every 10 seconds measurements are taken to ascertain:

Lamp Function and Brightness

Over time, all UV Germicidal Lamps will lose brightness and impurities in the air will contaminate the surfaces.  The in-built UV monitor will alert the user that a service is required once this reaches a threshold.

Air Quality

The integrated air quality monitor measures air impurities down to 0.1um. This information is recorded and sent back to the building’s base unit every 10 seconds to show real-time air quality information.

Air Flow and Air Exchange Rates

By constantly monitoring air-flow volume through each one of the Induct units, the React-Air system calculates the number of hourly, daily, and weekly air exchanges in your building.

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 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.
