ABSTRACT:
The present invention relates generally to a filtration article, such as a protective facemask, a method for using a filtration article, and a method for preparing a filtration article. In particular, the invention relates to a protective facemask that cost-effectively offers a broad spectrum of antimicrobial protection through the use of fibers treated with one or more oligodynamic metal and/or salt of an oligodynamic metal.
