Abstract: The present disclosure provides adhesive articles that can be removed from surfaces without damage by having reduced or eliminated contribution of a core backing to peel force generated by the adhesive during removal. In some instances, this can be accomplished by a core that loses structural integrity in a direction normal to a plane defined by a major surface. In other instances, the contribution is reduced by compromising the interface between the core and a peelable adhesive layer.

Abstract: The present disclosure relates to air filters. More particularly, it relates to adjustably sized air filter systems useable in window opening. Some exemplary window air filter assemblies include two u-shaped frame members that can be coupled to form an adjustable frame assembly; and a filter media assembly that is attachable to the frame assembly and that includes an adjustable length media. The window filter assemblies are capable of moving between a collapsed state to an expanded state.

Abstract: The present disclosure relates to multi-layer composite articles including at least two nonwoven web layers. Each or the layers may be a spunbonded web, and each may include biodegradable materials. The multi-layered composites of the present disclosure are particularly well suited for air filtration, as they can combine a high dust holding capacity with sufficient strength, dimensional stability, and a relatively low pressure drop.
