These Style V micro paper bags fit Eureka canister vacuums and come three to a pack. The micro-lined paper captures fine dust and debris and seals to the bag collar so the airflow passes through the filtration rather than around it. When a bag fills or develops a tear, suction drops sharply and fine dust can escape back into the room. Swapping in a fresh bag restores strong airflow and keeps captured debris sealed inside, and a pack of three keeps spares ready between changes. Fits: Eureka Style V canister vacuums Quantity: three micro paper bags per pack Benefit: restored suction and clean filtration Part: also referenced as #154SW Each bag seats onto the canister's bag collar in seconds. Change it at about two-thirds full, and confirm compatibility with your specific Eureka model before ordering.
