A new study has shown that Airocide air purifiers can eliminate SARS-CoV-2, the novel coronavirus that causes COVID-19. In 2020, the World Health Organization designated the outbreak of COVID-19 a global pandemic, and we’ve been working to determine how effective the photocatalytic oxidation (or PCO) and filtration technology inside Airocide is at fighting this virus. The results from a recent study show serious promise – with up to a 99.94% reduction of the SARS-CoV-2 virus in testing. Here’s a basic overview of how our Airocide units were tested, and the results we saw.

SteriLumen, Inc. worked with MRIGlobal on a series of tests to determine the efficacy of Airocide air purification products at eliminating aerosolized SARS-CoV-2. Under tightly controlled conditions, both for reliable and repeatable test results and a safe environment for testing staff, they tested the Airocide technology in three distinct ways. They tested an Airocide unit with its integrated particulate filter and an active PCO catalyst, a unit with an active catalyst and no filter, and an unpowered unit as a baseline control test.
To start, MRIGlobal built a specialized system to conduct the tests: a Plexiglas chamber fitted with aerosol generation and sample collection systems inside a sealed protective cabinet. Each unit was tested under the same conditions, for the same amount of time – including the unpowered control unit. Each unit was placed in the chamber, powered on and allowed to warm up for 20 minutes, and the chamber was then filled with aerosolized SARS-CoV-2 for 10 minutes. Samples were collected 5 minutes and 30 seconds after the chamber was filled with the virus, then at regular intervals during the testing period, for up to 30 minutes.
MRIGlobal’s report shows the reduction or deactivation of SARS-CoV-2 in the tested air. MRIGlobal’s results were reported in a scientific measure known as log reduction. Converted to percentages, the virus was reduced by 99.94% by the Airocide unit with a particulate filter and PCO catalyst within 5 minutes and 30 seconds of operation, and 99.05% by the unit with a catalyst and no filter during the 20-30 minute test period.
The results show it clearly, viable SARS-CoV-2 was eliminated or removed from the tested air in significant amounts by the active Airocide units. It echoes similar results we’ve seen with unwanted organic particles like bacteria, other viruses, and fungal spores. When the PCO reactor in an Airocide unit processes air with unwanted organic particles, it’s not just trapping them. With or without filtration, organic particles that enter the reactor are destabilized and destroyed. That means less viable pathogens circulating in your air.
