A Test Bed for Evaluating Graphene Filters in Indoor Environments

Air pollution has been proved to be responsible for several health hazards. This is particularly an issue for indoor environments, where people usually spend most of their time. The research in air purifiers is then becoming more and more important to guarantee healthier indoor environments. A new class of air filters based on graphene can represent a valid solution thanks to the capability to filter out very small particles, like PM1, particularly harmful to health. The aim of the research presented is to evaluate the performance of different configurations of graphene-based filters. This paper describes the test bed designed to evaluate the filters. The testbed is a home automation IoT-Cloud prototype able to dynamically set up variable values of voltage or current filters, according to different user defined profile, thus changing the filtering capacity that depends on the crossing electricity. Finally, results obtained using different filter configurations are reported.
