Self-cleaning multifunctional air-filtration devices

Abstract

Air filtration is a key approach for removing particulates or pathogenic microorganisms. Traditional air filtrations use filters with limited removal capacity and must be thoroughly maintained. In this Device issue, Schütt, Adelung, and co-workers present a self-cleaning air-filtration system based on graphene-enhanced ceramics. The device removes particles and microbes and monitors airflow and loading state of the filter.
