Systems and methods are disclosed that include providing a filter assembly having a filter body with an inlet and an outlet, a filter membrane support disposed within the filter body between the inlet and outlet, a filter membrane coupled to the filter membrane support, and at least one component that passes through the inlet, the filter membrane support, and the outlet to carry an electrical current, a fluid, or combinations thereof through the filter.

Systems, devices, and methods for detecting contamination (e.g., bacteria) in fluid are provided. The systems, devices, and methods allow for filtering a fluid sample using a filter to capture and concentrate cells (e.g., bacteria) to detect electrochemical properties thereof. The cells can be exposed to a reagent that diffuses into the cells to produce a product of interest that can be used in analysis of the fluid sample. The product of interest can diffuse out of the filter into a fluid storage component for detection and analysis by an analysis component. After the sampling is completed, the filter can be detached and discarded. Other aspects of the present disclosure, including enhancements and various systems and methods for concentrating cells and analyzing the same, are also provided.

A composite media alternative to high pressure drop glass microfiber HEPA media for use in applications where HEPA efficiency with an oily aerosol challenge with low resistance are required. The composite media contains two light filtration layers, one or both of which is charged, and the efficiency of the material can be greatly increased over a single layer containing the same weight of material. The composite media contains a backer layer to provide mechanical support to the filtration layers.
