摘要： A covering includes an outer material, a plurality of conductive-fibers, and a fastening material. The outer material includes a front surface and a back surface and the conductive-fibers are disposed between the front surface and the back surface. The conductive-fibers are configured to receive a voltage that causes the conductive-fibers to repel and remove dust from the front surface of the outer material. The fastening material is coupled to the back surface of the outer material and facilitates releasably attaching the outer material to an article.

摘要： The invention relates to a method and an apparatus for measuring particle concentrations in an aerosol. The apparatus comprises means (103) for driving flow (105) into apparatus (101), means (115) for electrically charging particles (109) to become electrically charged particles (123) by ions (113) produced by a charger, means (117) for removing free ions (113) which are not attached to the electrically charged particles (123), and means (119) for measuring electrical current carried by the electrically charged particles (123). The means (115) for charging the particles and the means (119) for measuring electrical current carried by the electrically charged particles (123) are dimensioned such that the means (119) for measuring electrical current carried by the electrically charged particles (123) only measures a part of a total current carried by the particles.

摘要： We disclose a window blind which purifies the surrounding air using electrostatic interactions. The window blind includes slats which may have a strip of positively charged material, a strip of negatively charged material, or both attached to the top of the slat. In some embodiments, the positively charged material and the negatively charged material are attached to alternating slats. In other embodiments, the positively charged material and the negatively charged material are attached to the top of the same slate with a strip of insulating material positioned between them. The window blind may include an air-moving device which moves air past the slats so that dust particles with either a net positive charge or net negative charge may be attracted to the oppositely charged material on the slat. The air-moving device may be a vacuum or a fan. The positively and negatively charged materials may be removeable for cleaning.

摘要： An apparatus and a method are provided for a heating, ventilation, and air conditioning (HVAC) system air filter for a building ventilation system. The HVAC system air filter comprises a supportive frame configured to orient the HVAC system air filter within the building ventilation system. A composite filter medium retained within the supportive frame comprises a cotton gauze portion and an electrostatic portion. The cotton gauze portion is configured for treatment with a filter oil composition to enhance airflow and filtration of air flowing through the composite filter medium. The electrostatic portion is configured to electrostatically attract and agglomerate airborne molecular contaminants and volatile organic compounds (VOCs) as small as 0.001 microns in diameter. In some embodiments, the composite filter medium comprises substances configured to release a fragrance into air passing through the composite filter medium.
