A fragrance dispenser and a corresponding method of dispensing fragrance, comprising at least one receptacle having a major open end, with a porous diffuser layer occlusively overlying the major open end of the receptacle, wherein at least a sectional area of the porous diffuser layer is removable to uncover a portion of the receptacle to control of the release rate of a fragrance source. The fragrance dispenser may comprise a plurality of receptacles and the porous diffuser layer comprises a plurality of sections that are individually removable to uncover each receptacle. The fragrance dispenser could comprise a removable cover sheet that is peelably detachable from the porous diffuser layer. Porous diffuser layer could be an organic polymeric nonwoven web and/or the receptacle is made of a thermoplastic organic polymeric resin. The fragrance dispenser may further comprise a secondary diffuser layer that has 50% more permeability that the porous diffuser layer.

Fragrance dispenser with user-selectable release rate

A substrate comprising a crosslinked polymer primer layer, and grafted thereto a ligand-functionalized polymer is provided. The grafted polymer has the requisite affinity for binding neutral or negatively charged biomaterials, such as cells, cell debris, bacteria, spores, viruses, nucleic acids, and proteins, at pH's near or below the pI's of the biomaterials.

Ligand functional substrates

A nestable framed pleated air filter, including a non-self-supporting, compressible, pleated air filter media with a plurality of oppositely-facing pleats and with a plurality of upstream pleat tips and downstream pleat tips and downstream pleat valleys, the pleated air filter media further including a plurality of bridging filaments that are bonded to at least some of the upstream pleat tips. The filter includes a frame with sidewalls that are angled so that the framed pleated air filter is nestable.

Nestable framed pleated air filter and method of making

Asymmetric articles are described including a porous substrate with two opposing major surfaces and a porous structure extending between the surfaces, and a polymeric coating on one of the major surfaces and extending into the porous structure to a depth of the porous structure. Methods for making an asymmetric composite article are also provided, including providing a porous substrate, treating the porous substrate with a plasma treatment or a corona treatment from one major surface to a depth of the porous structure between the two major surfaces. The method further includes applying a coating solution to the treated porous substrate and drying the coating solution to form a composite asymmetric composite article having a polymeric coating on one major surface and extending into the porous structure to the depth of the treated porous structure.

A fragrance dispenser for emitting fragrance into an airstream impinging on an air filter, the dispenser having a receptacle with an open end that faces toward the air filter and that has a porous diffuser layer occlusively overlying the open end of the receptacle.

Fragrance dispenser for air filter

Described herein is a filtration media comprising: (i) a first filtration medium comprising an anion exchange nonwoven substrate, wherein the anion exchange nonwoven substrate comprises a plurality of quaternary ammonium groups; and (ii) a second filtration medium comprising a functionalized microporous membrane wherein the functionalized microporous membrane comprises a plurality of guanidyl groups; wherein the first filtration medium is positioned upstream of the second filtration medium.

Filtration medium sequence for biomaterial purification

Ligand functionalized substrates, methods of making ligand functionalized substrates, and methods of using functionalized substrates are disclosed.

Ligand functionalized polymers

The present disclosure generally relates to air filters expandable from a collapsed arrangement to an expanded, end-use arrangement and to methods of making, using, and installing such air filters. Some embodiments relate to an air filter having an expanded state and a collapsed state. The air filter includes a filter media assembly including (1) filter media including a plurality of pleats, (2) first and second opposing sides, and (3) first and second opposing ends. The air filter also includes a shape retention structure capable of being connected to at least a portion of the filter media assembly and capable of retention the filter media assembly in the expanded state. A spacing distance between adjacent pleats in the filter media is greater in the expanded state of the air filter than in the collapsed state of the air filter. In some embodiments, the air filter is an HVAC air filter.

Collapsible air filter

Method of making ligand functionalized substrates

Porous polymeric resins, reaction mixtures and methods that can be used to prepare the porous polymeric resins, and uses of the porous polymeric resin are described. More specifically, the polymeric resins typically have a hierarchical porous structure plus reactive groups that can be used to interact with or react with a variety of different target compounds. The reactive groups can be selected from an acidic group or a salt thereof, an amino group or salt thereof, a hydroxyl group, an azlactone group, a glycidyl group, or a combination thereof.
