Product Description

The Eureka Express Filter (part 37788) is an OEM replacement filter engineered for Eureka Airspeed and Boss upright vacuum models. This filter maintains optimal airflow and suction power by capturing dust, allergens, and debris during operation. Part 37788 is a direct-fit replacement that restores your vacuum's filtration efficiency when the original filter becomes clogged or worn.

The filter is designed with durable, pleated media construction to maximize surface area and filter life. Regular replacement ensures your Eureka vacuum maintains peak performance and extends motor life by preventing debris bypass.

Compatibility: Eureka Airspeed, Eureka Boss, and select Eureka upright models. Cross-compatibility with some Hoover models may apply depending on vacuum configuration.

Regular filter changes (typically every 3–6 months depending on use) keep your Eureka running efficiently and protect the motor from debris damage.
