IMPROVED SORBENT LOADED WEBS FOR GRAVITY FILTRATION

摘要

A filter media is disclosed comprising a carrier and a web collected on the carrier. The web comprises hydrophilic polymeric meltblown fibers and a plurality of sorbent particles enmeshed in the hydrophilic polymeric meltblown fibers. The carrier comprises a porous sheet and has a carrier basis weight. The web has a web basis weight. The hydrophilic polymeric meltblown fibers comprise at least 3% of the web basis weight and the plurality of sorbent particles comprise at most 97% of the web basis weight.
