With the rising concerns about COVID-19 particles dispersion in air ducts in commercial buildings such asmalls and offices for instance, more efficient filtration systems are emerging. The development of a hybridcomposite system of adsorbent materials that leverages the synergistic effect of both GAC,thermo-mechanically exfoliated graphene, activated alumina and organic binders such as methyl-cellulosecould be beneficial to drastically improve the filtration performances. Moreover, as graphene is anelectro-conductive material, a very low-voltage impulse can be dispersed into the graphene filter and eliminatethe virus and bacteria trapped in it. The COVID-19 situation has shown the danger, to some extent, of openworking space and it may be difficult for some companies to reopen such large space unless they have anefficient air filtration system which is tailored to neutralise and kill the viruses transmitted through the ductventilation. Both on an economical and social perspective, the development of new efficient air filters wouldprovide tools to address these concerns.

随着人们对COVID-19颗粒在商业建筑（例如商场和办公室）的空气管道中扩散的担忧日益增加，更高效的过滤系统正在出现。利用GAC、热机械剥离的石墨烯、活性氧化铝和有机粘合剂（如甲基纤维素）的协同效应的吸附材料的混合复合系统的开发可能有利于大幅提高过滤性能。此外，由于石墨烯是一种导电材料，一个非常低的电压脉冲可以分散到石墨烯过滤器中，并消除被困在其中的病毒和细菌。COVID-19的情况已经显示了危险，在某种程度上，一些公司可能很难重新开放这么大的空间，除非他们有一个有效的空气过滤系统，专门用来中和和杀死传播的病毒。通过通风管道。从经济和社会的角度来看，开发新的高效空气过滤器将为解决这些问题提供工具。
