Abstract: A process is provided for removing viruses and micro-organisms from building air by inactivation of those biological elements within an HVAC filter having exuding halogenated material therein. The filter for the HVAC systems has the exuded halogenated material applied with a tackified material via a sequential spraying operation prior to heat curing either of those materials. The filter can subsequently be formed with other laminated materials for increased efficiency, and pleated for use in the HVAC system.

Abstract: A panel filter includes a first media layer constructed from a first material that is permeable to air and impermeable to particulates of a targeted size or type, a support grid, and a second media layer constructed from a second material that is permeable to air. The second media layer is adhesively coupled to the first media layer without a mechanical seal. When the first media layer and second media layer are coupled, the support grid is retained between the first media layer and the second media layer.

Abstract: The present invention relates to a fire retardant binding tape. The binding tape is employed to affix the butt splice joint (or overlapping joint) between rolls of fire retardant material, where one roll ends and another begins. Should the binder tape be subject to elevated temperatures, it will shrink toward the joint seam, thus strengthening the seam, and form a char that minimizes heat input to the flammable materials (foam) located beneath the fire retardant barrier material. The nonwoven binding tape has fire retardant cellulosic fibers, a low melt binder, and an adhesive on one side used to affix the binding tape to the edge butted pieces of a flame retardant barrier material. Instead of the low melt binder, the fibers may be mechanically secured. Optionally a carrier film layer may be used to make the tape more rigid.
