Abstract
The invention relates to a coated porous medium comprising metal particles. The metal particles define a free area surface S. The free area surface S is substantially completely coated with a coating layer. The coating layer is substantially conformal, substantially uniform in composition and has substantially the same thickness over the whole free area surface. The invention further relates to the use of a coated medium as filter medium and to a method of manufacturing a coated medium.

1-13. (canceled)
A method of manufacturing a porous metal medium that comprises:
- (A) providing a porous metal medium that includes metal particles defining a free area surface S;
- and
- (B) applying a coating layer on the free area surface S using atomic layer deposition such that the coating layer covers the free area surface S substantially completely and the coating layer is substantially conformal, substantially uniform in composition and substantially uniform in thickness over the free area surface.
