Researchers have developed a paper filter, which can remove virus particles with the efficiency matching that of the best industrial virus filters. The paper filter consists of 100 percent high purity cellulose nanofibers, directly derived from nature. Cellulose is one of the most common materials to produce various types of filters because it is inexpensive, disposable, inert and non-toxic.
