A filter device and method are provided for treating parenteral nutrient fluids, particularly TNA systems containing lipids, glucose, and amino acids. The filter device comprises a housing and a microporous medium in the form of a synthetic polymeric microporous structure having a pore rating of less than 1.2 micrometers. A preferred microporous medium comprises, in series, a matrix of microfibers which has been radiation grafted to render the matrix wettable by parenteral nutrient fluids followed by a microporous membrane, also wettable by parenteral nutrient fluids, and having a finer pore rating than the microfibrous matrix.
