Abstract: An air filter assembly includes a pleated air filter media having an upstream surface, a downstream surface, a first side end, and a second side end; a wire netting adjoined to the downstream surface of the air filter media; and a graspable end member adjoined to each of the first and second side ends of the air filter media. The assembly further includes a frame configured to releasably retain the air filter media, the frame having first and second ends walls and first and second side walls; a closure assembly for securing the air filter media within the frame, the closure assembly comprising a spring-loaded fastener pivotably coupled to at least one of the first and second side walls and configured to fasten to at least one of the first and second end walls; and an efficiency grid retained within the frame.

Abstract: A two-phase cosmetic composition is provided packaged in a clear container. Within the container is an oil and an aqueous phase separated from one another but when shaken form a highly temporary, clear emulsion. One of the phases is colored with a dye while the other is ordinarily water white. Color stability may be enhanced through use of a UV protectant. A bead control agent may be included to eliminate unsightly bead formation on walls of the container. Sorbitan derivatives are useful for this purpose.
