When the filter element containing the nano silver particles is used, a certain amount of water exists in the air, so that the surfaces of the nano silver particles are oxidized to release trace silver ions, and the silver ions are positive charged cations formed by the fact that one or more electrons of the silver atoms are lost, so that the filter element has an oxidation effect. Silver ions strongly attract sulfhydryl (-SH) groups on protease in bacterial bodies and are quickly combined with the bacterial bodies to ensure that the protease loses activity and causes bacterial death, and when the bacteria are killed by the silver ions, the silver ions are free from bacterial debris and are contacted with other bacterial colonies, and the processes are repeatedly carried out, so that the bacterial killing result is achieved. Meanwhile, silver ions can also kill viruses by inactivating the viruses without infectivity caused by the coagulation of protein molecules of the viruses and the binding of electron donors on DNA molecules thereof.
