A filtration system comprises a malleable compartment and a handle. The malleable compartment has a permeable fabric forming an exterior of the malleable compartment. The exterior at least partially faces a contaminated fluid. The permeable fabric has a pore size that defines the permeability of the fabric. The malleable compartment also has an interior that holds an interchangeable microfiltration medium. The microfiltration medium has a pore size that is smaller than the pore size of the permeable fabric. The filtration system also comprises a handle that is affixed to the malleable compartment.
