摘要：
A filtration system for use in connection with a central vacuum system in a hospital or other medical facility. In certain aspects, the filtration system comprises a removable filter for removing contaminants； a fitting adapted for connection to a central vacuum source/system which provides constant suction, which fitting is positioned between the filter and the central vacuum source； a flow control valve positioned between the filter and the fitting； wherein the relative positions of the fitting, flow valve and filter prevent contaminants from being discharged into the central vacuum system. In other aspects, the system provides variable filter life based upon variable flow.
