The present disclosure generally provides systems and methods for easily replaceable, high efficiency particulate air or HEPA-quality filtration for vacuum systems in an effective, efficient, and cost-sensitive manner. As an example, the HEPA filter cartridge could include a minimizer and connecting structures associated with an exhaust of such a HEPA filter cartridge. The surface area of the minimizer or the connecting structures could be increased or decreased to control, restrict, or otherwise maintain a predetermined, preferable, or allowable amount of backpressure subjected to the HEPA filter cartridge or other suitable performance characteristic.
