Perforating graphene which is used as gas filters involves exposing a stream of gas into plasma to generate an activated gas stream; directing the gas stream toward a graphene sheet; and perforating the graphene sheet with the gas stream.

Deionizing fluid carrying unwanted ions involves applying pressurized fluid to first surface of perforated graphene in cylindrical form, so that fluid flows to second side of the sheet in preference to ions; and collecting the fluid.
