Micron Magic HEPA Filter Plus offers maximum filtration for your Kirby vacuum. While other vacuums allow dirt to seep out while cleaning, our Kirby HEPA filter traps common household dust, pollen and other particles. Electrostatically charged material traps micron particle matter. Keep your home smelling fresh by trapping dirt, dust, pet hair and more inside the Kirby HEPA filter bag. Universal Style fits both F-Style and Twist-Style Kirby Models. Works with G4, G5, Gsix, Ultimate G, Ultimate G Diamond, Sentria, Sentria II, and Avalir models.
