The liquid-impermeable, vapor-permeable material allows water to evaporate and be transmitted outside of the container. The evaporation allows more fluid to be processed by the container than the container could otherwise hold. Other systems, methods, and apparatuses are presented. ## Claims ### Claim 1 A system for treating a tissue site with reduced pressure, the system comprising: a manifold configured to be placed proximate to the tissue site;
