Abstract
An infection control bedding product such as a pillow, duvet, mattress, cushion or such like having a sealed cover and having a deformable filling material, may comprise a liquid impermeable air permeable microbial barrier vent. The vent includes an oleophobic expanded polytetrafluoroethylene (PTFE) membrane extending past the perimeter of the aperture and a nonwoven layer extending past the perimeter of the aperture. A gasket may be bonded to the PTFE membrane, the nonwoven layer and the cover to form a liquid impermeable seal rendering the infection control bedding product liquid impermeable.
