Graphene is a sheet of Carbon atoms, or one layer of Graphite ("lead" in a pencil). A graphene filter is a filter made of graphene.
Graphene is pretty amazing. An adequate description of the properties is rather long. There is a link below to the properties section of an article on graphene.

Graphene is formed by peeling extremely thin layers of graphite off of a larger piece, in the original paper published on graphene it was done using tape.
Graphene is a very thin layer of graphite. It is so thin, it is so close to being invisible!
The molecular structure of graphene differ from the other allotropes of carbon diamond and graphite in that graphene consist of a single layer of atoms.
graphene according to how much it can hold (calculator) and how dense it is.
It would take an elephant, balanced on a pencil, to break through a sheet of graphene the thickness of Saran Wrap."
Appropriately injected graphene (and boron nitride hBN) can allow energetics to get through it, offering the potential for using graphene layers as a barrier that blocks liquid atoms. They could even be used to gather hydro energy out of the atmosphere that could power electric generators with ambient space. The membranes are more effective at elevated temperatures and when covered with nanoparticles. Graphene could solve a major problem for fuel cells: fuel intersection for efficiency and durability.
