RE: Water Filter

Generaly a particle is considered dissolved if it goes through a 0.45uM (micron) mesh.

Nearly all dissolved compounds are much smaller than 2 microns. You need to get down to the angstrom level before dissolved compounds are removed. Such a filter will remove many parasites but won't affect your TDS or DOCs.
