Abstract
A collapsible bag or compressible bottle container for accepting, holding, and filtering fluid. Fluid is filtered upon entry to the container or filtered upon egress. The filter media resides either in a removable cap, or in a second fluid-tight compartment attached to, and in fluid communication with, the container body. A one-way valve with unique one-time connection to a fluid source mitigates potential contamination from container overuse. A second collapsible layer is used in conjunction with the collapsible bag to accept compressed air that provides rigidity for the container body.
