摘要： Method for making a filter cartridge that is suitable for attachment to a respiratory mask. The method comprises the steps of (a) providing a mass of filter material; (b) providing a filter cartridge housing that has an inlet and outlet and a sidewall that includes sheet material; and (c) thermoforming the sheet material of the housing sidewall around at least part of the mass of filter material to place the housing sidewall in direct contact with the mass of filter material to encapsulate the filter material so that fluid is prevented from passing through the filter cartridge from the inlet to the outlet without being filtered by the mass of filter material.

摘要： A porous sheet article comprising a self-supporting nonwoven web of polymeric fibers and at least 80 weight percent sorbent particles enmeshed in the web, the fibers having sufficiently greater elasticity or sufficiently greater crystallization shrinkage than similar caliper polypropylene fibers and the sorbent particles being sufficiently evenly distributed in the web so that the web has an Adsorption Factor A of at least 1.6×104/mm water. The articles have low pressure drop and can provide filter elements having long service life and an Adsorption Factor approaching and in some instances exceeding that of a packed carbon bed.
