AirSani in Action
Validating the effectiveness of AirSani, with experimental data.
We used real-world experimental data to test the effectiveness of the AirSani in reducing the person-to-person transmission of airborne diseases.

In order to test AirSani’s degree of effectiveness in stopping the transmission of airborne disease, we have simulated various case scenarios in the absence and presence of AirSani. The first series of simulations is simulating a coughing scenario in a typical office room. The office is 12′ x 12′ and has a 9′ high ceiling.

To ensure that our simulations closely mimic real-world events, we used particle distribution, cough speed, and duration from experimental data published in peer-reviewed scientific journals, such as the following article by Han et.al. https://doi.org/10.1098/rsif.2013.0560.

 

What is happening in the video?

The video on the left side simulates an office, where one of the personnel is infected and suddenly and unintentionally coughs without properly blocking her mouth. We use computational fluid dynamics to simulate and predict the distribution of aerosols and droplets from the cough throughout the room over time. Then we measure the chance of infection for various people in the room, based on the virus-carrying aerosols/droplets reaching them over time.

As the results on the left side show, all the people in the room, have a high chance of catching the virus in this scenario. (the video on the bottom-left shows the top view of the room)

 

The video on the right side simulates the same situation with one major difference: i.e. the office is equipped with an AirSani unit. AirSani uses advanced AI, along with an array of sensors to constantly monitor the environment for health-risking events, such as cough and sneeze. Once it detects an event, the intelligent AI system measures the associated risk and predicts the trajectory of particles. Then the advanced active beam steering on AirSani utilizes its four UV engines to disinfect the predicted trajectory in real-time, while it ensures that the disinfection is happening at a safe distance from the people in the room.

The disinfection zones are visible on the top view, as four green boxes through the video, where they constantly reposition themselves over time, to offer the most effective disinfection.

The results show a dramatic reduction in infection risk for individuals in the room.

Recent Studies show that once virus-carrying aerosols are spread in the air, the chance of infection is 90% within the first 20 minutes, where the first 5 minutes have the highest chance of getting individuals sick. These findings suggest that existing UVC disinfection solutions such as far-UV and upper room UV, which take tens of minutes to disinfect the viruses in aerosols, are not effective in stopping the person-to-person transmission of diseases. In contrast, the active and real-time UVC disinfection by AirSani can destroy the viruses across the room within seconds, and consequently reduce the chance of infection about 20X compared to alternative UVC solutions.

 

AirSani can easily be installed in any indoor space. See AirSani in action in various setups below.
