These Eureka Style Micro Upright Paper Bags are replacement dust bags supplied in a pack of five for compatible Eureka upright vacuums. Each bag captures dirt and fine dust as air passes through it, keeping the airflow path clean. Old or overfilled bags are the most common cause of weak suction in a bagged vacuum, because a clogged bag chokes the airflow the motor depends on. Running past that point strains the motor and leaves debris behind on the floor. Fitting a fresh bag restores full airflow and filtration, and this five-pack keeps spares on hand between cleanings. Type: micro-filtration upright paper bags Quantity: 5 bags per pack Benefit: restores full suction and clean filtration Tip: replace a bag once it is about two-thirds full An alternative version is also offered as part #63213B. Check the bag style against your specific Eureka model before ordering to be sure of the fit.
