The Eureka Style DCF9 Filter (Part # 618830) is a finely engineered replacement filter designed to help restore peak suction and filtration performance in compatible Eureka and Hoover Air upright vacuum cleaners. When your vacuum begins to lose airflow or you notice more fine dust floating back into the air, replacing the dust cup filter is a critical first step toward restoring optimal cleaning efficiency.

Manufactured from high-quality, pleated filtration media, this filter is built with durability and long service life in mind. The rigid plastic frame ensures a secure and reliable fit within the dust collection chamber, while the precise dimensions match the original equipment manufacturer (OEM) specifications for the DCF9 style filter. This ensures proper alignment and sealing, preventing bypass and maintaining efficient airflow through the vacuum system. 

Installing the DCF9 filter is straightforward: simply remove the old filter from your vacuum’s dust cup or chamber, insert the new filter in the same orientation, and reassemble. This replacement fits models such as the Eureka 2940, 2970, and 2980 series uprights, and by installing a fresh filter you’ll experience improved airflow, restored suction power, and enhanced dust containment. 

At Swiss Boy Vacuum, we’re committed to supplying only reliable, high-quality replacement parts that meet or exceed OEM standards. When you purchase the DCF9 Filter from us, you can be confident you’re selecting a trusted product backed by expert support and fast shipping built for professional-grade cleaning systems.
