Improvement of indoor air quality using a smart gate that can lessen viral aerosol (MS2 virus) and particulate matter (PM): Experimental findings

Abstract

Fine particulate matter (PM) and viruses have more detrimental impacts on human health when present in an indoor setting than when present in an outdoor environment. With the COVID-19 epidemic, a healthy indoor environment has emerged as a crucial necessity. There are many different cleaning technologies available, but most of them have drawbacks and are challenging to utilize in daily-use indoor venues including workplaces, retail malls, movie theaters, subway stations, and many other locations. We created a portable, smart gate that is simple to use at a commercial level and evaluated it for effectiveness in lowering particulate matter concentrations of various sizes. The results show that 97.76% for PM10, 97.72%PM4, 97.44% for PM2.5, and 96.91% for PM1. reduction. Also, the aerosolized MS2 virus was used to test its ability to decrease viral transmission and the viral reduction efficiency of the smart gate was found around 82%. The experimental results show that the smart gate is better than all the current available cleaning technologies along with its user-friendly and easy use.
