ABSTRACT:
The invention relates to a filter with a predeterminably adjustable porosity. The filter can be manufactured by forming a three-dimensional framework made of the filter material around particles, which serve as space retainers for the porosity, and subsequently removing the particles. The filter according to the invention consists of biologically inert material which does not harm the mucous membrane. When used as a nose filter, the filter keeps the breathing air free of particles and harmful gases.
