These Eureka canister paper bags are two-ply EnviroCare replacement bags for Eureka style B and S canister vacuums. The two-ply paper captures dust and debris while letting air pass through to keep suction steady. A bag that fills up restricts airflow and drops cleaning power, and an overfilled bag can release trapped dust back into the room. Swapping in a fresh bag keeps suction strong and holds allergens inside for cleaner air as you vacuum. Fits: Eureka canister vacuums using style B and S bags Construction: Two-ply paper filtration Benefit: Steady suction and reliable dust capture Tip: Also sold as part #52329C-6; change the bag at about two-thirds full The bags fit the Eureka B and S bag mount for a direct replacement. Confirm your Eureka model uses style B and S bags before ordering so they match your machine.
