1. A device configured to be in fluid communication with an article, the device comprising:
a housing having a first port, a second port, and an intermediate section; the intermediate section having a first flow path between the first port and the second port, and a second flow path between the first port and the second port, the first flow path separated from the second flow path by a heat and moisture retaining media, the housing including a valve mechanism in the intermediate section, the valve mechanism comprising
an element forming an aperture having a radially extending ridge, andan obstruction member, the obstruction member comprising an arm pivotably coupled to a base, the base having a first surface and an opposing second surface, the second surface of the base coupled to the heat and moisture retaining media, the arm having a first surface and an opposing second surface, the arm configured to contact the ridge at a first point of travel; and a seal disposed on the first surface of the arm and the first surface of the base, the seal compressed between the ridge and the first surface of the arm at the first point of travel to form a variable compression interface so as to restrict fluid leakage across the variable compression interface between the arm and the ridge, wherein the seal comprises a sheet or web of compressible filter media formed of non-woven material configured to (i) conform its shape under biasing forces at the variable compression interface; and (ii) trap particles, attempting to pass across the variable compression interface, in the non-woven material; wherein the arm at the first point of travel directs the fluid through the first flow path, and a second point of travel directs the fluid through the second flow path. |
