Abstract
Filter media are provided having improved conductivity to enhance filtration efficiency and/or dissipate static charge, and methods for making the same. In one exemplary embodiment, the filter media can include a filtration substrate, and at least one conductive coating disposed on at least a portion of the filtration substrate. In use, the conductive coating is coupled to an energy source and it is effective to emit ions when energy is delivered thereto to increase the efficiency of the filtration substrate and/or to dissipate or eliminate static charge generated during filtration.
Claims25
A filter media, comprising:
- a non-woven fiber web;
- and
- at least one conductive coating that coats at least a portion of the non-woven fiber web, wherein the conductive coating is formed from a conductive polymer, and
- wherein the filter media is at least one of a HEPA filter media, an ULPA filter media, and an ASHRAE filter media.
A filter media, comprising:
- a non-woven fiber web comprising glass fibers having a diameter in the range of about 0.3 to 4.0 microns;
- and
- at least one conductive coating that coats at least a portion of the non-woven fiber web, wherein the conductive coating is formed from a conductive polymer,
- wherein the filter media is at least one of a HEPA filter media, an ULPA filter media, and an ASHRAE filter media.
