Abstract: A portable air filtration system for efficiently installing an air filtration system to a barrier which may be easily removed or replaced. The portable air filtration system generally includes a filtration unit which is adapted to be secured to a barrier over an opening in the barrier. The filtration unit includes a first connector which may include a fastener or a magnetic element. A second connector is provided to secure the filtration unit to the barrier, with the second connector including a fastener or a magnetic element on its first side to engage with the first connector and an adhesive on its second side to engage with the barrier. The filtration unit may also include a removable one-way valve such as a flap and an optional secondary filter.

Abstract: A segmented closure system for providing a closure strip of variable length capable of allowing the efficient opening and closing of an object to form a barrier such as a temporary door. The segmented closure system generally includes a pair of closure members each including a magnet for removably securing the closure members together. Each closure member includes a fastener for securing the each closure member to an object, such as to a pair of adjoining plastic sheets to form a temporary barrier such as a door. Each closure member may include mating connectors for linking the pair of closure members together end-to-end in a linear or angled orientation. Each closure member may include a pivotable segment connected to its main body by a connector pin. Temporary barriers of variable sizes may be easily constructed by interlinking multiple closure members together on opposite edges of a pair of plastic sheets.

Abstract: A reusable closure system for providing easy closure and opening of an object such as a sheet forming a barrier. The reusable closure system generally includes a backing member adapted to be secured to an object, such as by an adhesive. A closure member may be connected to the backing member, with the closure member including a first portion which is removably connected to a second portion by one or more magnets. An optional outer closure member may be connected to the closure member, with the outer closure member including a zipper. Thus, the reusable closure system may be secured to various objects to allow for selective opening or closing of the objects in a versatile, user-selected manner.
