| 20100043639 | HIGHLY CHARGED, CHARGE STABLE NANOFIBER WEB - A charged multilayer filter includes a hydrocharged filtration layer containing a plurality of intertwined nanofibers that have a finite length of about 12 to about 300 mm, atop a porous roll-to-roll processable support layer. | 02-25-2010 |
| 20100229725 | Systems and Methods for Processing CO2 - Systems and methods for lowering levels of carbon dioxide and other atmospheric pollutants are provided. Economically viable systems and processes capable of removing vast quantities of carbon dioxide and other atmospheric pollutants from gaseous waste streams and sequestering them in storage-stable forms are also discussed. | 09-16-2010 |
| 20120210875 | APPARATUSES AND METHODS FOR REDUCING POLLUTANTS IN GAS STREAMS - Apparatuses and methods for reducing pollutants in a gas stream are disclosed. The gas stream is introduced into a condensation chamber to condense the gas stream. It then proceeds into a first reaction chamber adapted to electrochemically alter the gas stream. From there, the gas stream is directed into a reduction chamber adapted to reduce pollutants and a resonance chamber adapted to ionize the gas stream. The gas stream is then directed into a second reaction chamber adapted to further reduce pollutants in the stream. After treatment, the gas stream may be discharged into the atmosphere or recirculated through the apparatus to further reduce pollutants in the gas stream, the latter providing for a closed-looped system. | 08-23-2012 |
| 20140150658 | HVAC FILTRATION SYSTEM - This invention pertains to interchangeable, disposable, air filtration pads, which work in conjunction with its double-sided flexible magnetic gaskets and mats. This system works both for return and supply side of the HVAC system. This multi-adaptable double-sided magnetic mat system is easily attachable and removable and compatible to current factory vent plates, and HVAC systems. | 06-05-2014 |
| 20150047507 | NESTABLE FRAMED PLEATED AIR FILTER AND METHOD OF MAKING - A nestable framed pleated air filter, including a non-self-supporting, compressible, pleated air filter media with a plurality of oppositely-facing pleats and with a plurality of upstream pleat tips and downstream pleat tips and downstream pleat valleys, the pleated air filter media further including a plurality of bridging filaments that are bonded to at least some of the upstream pleat tips. The filter includes a frame with sidewalls that are angled so that the framed pleated air filter is nestable. | 02-19-2015 |
| 20150047508 | FRAMED PLEATED AIR FILTER WITH UPSTREAM BRIDGING FILAMENTS - A framed pleated air filter, including a non-self-supporting, compressible, pleated air filter media with a plurality of oppositely-facing pleats and with a plurality of upstream pleat tips and downstream pleat tips, the pleated air filter media further including a plurality of bridging filaments that are bonded to at least some of the upstream pleat tips. The framed pleated air filter does not include any support member on the downstream face of the pleated air filter media. | 02-19-2015 |
| 20150082985 | RECIRCULATION FILTER FOR AN ELECTRONIC ENCLOSURE - A filter assembly for use in an electronic enclosure is provided. The filter assembly includes a highly permeable scrim that defines an elongate enclosure with an inlet at a first end and a closed second end, wherein an electrostatic filtration media is disposed within the elongate enclosure. | 03-26-2015 |
| 20150107457 | ELECTRET NANOFIBROUS WEB AS AIR FILTRATION MEDIA - The present invention is directed toward an improved air filtration medium comprising a single layer polymeric nanofibrous web comprising a single source randomly intermingled fiber network with electrostatic charge up to −20 kV, a filtration efficiency range from about 70% to about 99.99%, and an air resistance less than about 2.5 mm wg for 0.3 diameter micron particles. The air filtration medium is made from a centrifugal melt spinning process. | 04-23-2015 |
| 20150292755 | REMOVABLE, UNIVERSAL COVER FOR AIR DUCT REGISTER - The present disclosure describes a filtration system that can be used with existing air duct registers on a heating ventilation and air conditioning (HVAC) system. The filtration system has a number of layers that limit the contamination of in home air with common pollutants such as mold, bacteria, dander, odors, and the like. The filtration system may also provide for a scent that is dispersed through natural use of the HVAC system. | 10-15-2015 |
| 20160067717 | ELECTRET WEBS WITH CHARGE-ENHANCING ADDITIVES - Electret webs include a thermoplastic resin and a charge-enhancing additive. The charge-enhancing additive is an arylamino-substituted benzoic acid or an arylamino-substituted benzoic acid salt. The electret webs may be a non-woven fibrous web or a film. The electret webs are suitable for use as filter media. | 03-10-2016 |
| 20160097352 | OIL REMOVAL APPARATUS - Embodiments of the present disclosure may suppress conduction between an anode and a cathode caused by condensed water in an oil removal apparatus in which oil particles are collected in a filter disposed between the anode and the cathode. An insulating layer may be sandwiched either between the filter and at least one of the anode and the cathode of the bipolar electrode, or within the filter so as to extend in a flow direction of blow-by gas, and may have an insulating property so as to prevent condensed water generated when moisture in the blow-by gas condenses, from connecting the anode and the cathode of the bipolar electrode. | 04-07-2016 |
| 20160184753 | AIR CLEANER AND HOME APPLIANCE HAVING AIR PROCESSING UNIT - Disclosed is an air cleaner having independent fluid paths and a home appliance having the air cleaner. The air cleaner includes a front panel having a plurality of air inlets formed thereon for air to flow in from outside of the case, first and second blower devices arranged inside the case to allow air to flow in through the plurality of air inlets, first and second filter units arranged to filter the air flowing in by the first and second blower devices, a first outlet located on the case to release the air, a second outlet formed at a different location from that of the first outlet, a first fluid path formed between one of the plurality of air inlets and the first outlet; and a second fluid path formed between another of the plurality of air inlets and the second outlet. | 06-30-2016 |
