In recent times, indoor air quality has become an important concern as it affects people’s health and comfort. According to WHO report, air pollution causes 7 million deaths every year. PM2.5 has been identified as a key pollutant which impacts human health causing diseases like stroke, heart diseases, breathing issues, cancer and so on [1].
In today's time, we travel by personal vehicle every day, commuting for hours. It is an extension to our homes. Unfortunately, due to frequent door and windows opening, the cabin air gets exposed to outside pollution, and we end up breathing pollutants. To mitigate the problem, air purifiers are added in the automobile.
As people are becoming more aware and conscious about good air quality, there is a growing demand for cabin interior air quality solutions for automobiles.
A popular approach is to add an air purifier inside cars like ones being used in our homes to bring down the PM2.5 levels. The air purifier consists of a filter, blower system, PM Sensor as well as a controller.
