Packed nine to a box, these Style RR upright micro paper bags are replacement bags for the Eureka 2434 and similar uprights. The micro-filtration media captures dirt and fine dust as air flows through, holding debris securely and keeping exhaust air clean. A bag left to overfill restricts airflow, weakens suction, and strains the motor, while a torn bag lets dust bypass filtration and blow back into the room. Fitting a fresh bag at the right interval keeps airflow and filtration where they should be. Fits: Eureka 2434 and similar upright models Construction: micro-filtration paper media Quantity: 9 bags per pack Tip: replace at roughly two-thirds full rather than waiting until packed Slide each bag onto the collar until it seats fully, and the nine-count pack keeps a season of spares ready. Confirm your Eureka model before ordering, and these bags maintain strong suction with reliable dust capture.
