Abstract: An apparatus and a method are provided for a heating, ventilation, and air conditioning (HVAC) home air filter to remove airborne molecular contaminants and volatile organic compounds (VOCs) from air within residential spaces. The HVAC home air filter a supportive frame having a shape and size suitable to orient the HVAC home air filter within a residential HVAC system. A filter medium is retained within the supportive frame to remove the airborne molecular contaminants and VOCs from air flowing through the residential HVAC system. The filter medium is a combination of media layers configured to exhibit a relatively high filtration efficiency and a low air pressure drop across the filter medium. The supportive frame comprises a plurality of elongate sections and corner sections disposed along perimeter edges of the filter medium to support the filter medium within the residential HVAC system so as direct air through the filter medium.

Abstract: In order to provide a method of introducing auxiliary material into the flow path of a crude gas stream charged with wet-paint overspray before the crude gas stream passes through at least one filter element for separating the overspray from the crude gas stream, with which method an introduction of auxiliary material into the application region of a paint shop is reliably prevented even in the event of incorrect operation, a method is proposed, which comprises the following method steps: detecting whether there is an adequate crude gas flow through the at least one filter element; and blocking the introduction of auxiliary material into the flow path of the crude gas stream if it is determined that there is not an adequate crude gas flow.

Abstract: Air filter embodiments include a frame that can be placed within an air flow. The air filter may also include one or more tape segments of an air-impervious adhesive tape. The tape segment can have a primary surface on which an adhesive material has been deposited, and a secondary surface opposite the primary surface. The tape segment can be supported on the frame such that an exposed portion of the primary surface is exposed to the air flow. Accordingly, at least some of the particulates in the air flow may adhere to the exposed portion of the primary surface, and thus be removed from the air flow. In some embodiments a conventional filter is also provided within the frame, and thus the invention may provide a replacement air filter for existing installations where replacement air filters are used.

Abstract: A filter element is made of a first filtering member, and a second filtering member that is arranged on a downstream side of the first filtering member and is impregnated with an oil. The first filtering member consists of a downstream wet layer that is impregnated with the oil, which is transferred by contact to the second filtering member, and an upstream dry layer that is not impregnated with the oil. A density of the first filtering member may be set smaller than that of the second filtering member.
