Abstract: Articles and methods relating to filter media are generally provided. In some embodiments, a filter media comprises a non-woven fiber web and a backer layer. The non-woven fiber web may comprise a plurality of continuous nanofibers, e.g., continuous nanofibers having an average diameter of less than or equal to 250 nm. The plurality of the nanofibers may comprise a plurality of nanoparticles at least partially embedded therein. In some embodiments, the plurality of nanoparticles makes up less than or equal to 15 wt% of the plurality of nanofibers. In some embodiments, a solidity of the non-woven fiber web is less than or equal to a solidity of the backer layer.
