Abstract: A kit that includes a base with a floor and four edges; a cover with a ceiling and four edges; and, four side panels, at least one of which is a framed air filter. The kit may be nestable. The kit is assemblable into an upwardly-open, horizontally-closed air-filtration assembly. The floor of the base may include multiple through-cuts and hinged connections that define multiple areas of the floor that are rotatable upward to provide multiple upwardly-protruding tabs; the ceiling of the cover may include multiple through-cuts and hinged connections that define multiple areas of the ceiling that are rotatable downward to provide multiple downwardly-protruding tabs.
