We aimed to addresse this challenge's aim by purifying abundant amount of air in a short period of time.
We thought one of the best solutions to prevent coronavirus spread, is to purify the air. We are inspired by ISS air purifying sysytems in the filter of our device. We used Raspberry Pie and Google Colab Research for coding. Since it is a virus, we are aware that we cannot acually "kill" it, so we used the advantage of the fact that COVID-19 is a RNA based virus and decided to inactivate its reproduction activities. To do so, we have chosen to use Far-UVC light leds in 222nm, which has no side effects on human but stil fatal to virus and bacteria. We applied a filter system on the device. The air will enter the device from the bottom and the filter on the top will release the purified and virus-free air. The device will be made of steel, to minimize the UVC exposure. During our research, we had a lot of complications. We couldn't use UVB because it causes skin cancer and eye irritation and we couldn't use plastic in the device where the air flows, because it turned out that plastic is not resistant to Far-UVC light. However, as we continued to research and develop our ideas, we determined that as we shorten the distance between the led and the target (virus or bacteria) , the effect of the light increases. As a result of our calculation, now, we are able to inactivate the virus and bacteria in 3.2 minutes.
