Dyson DC37 – Plus.Parts® Replacement Washable HEPA Pre-Filter

The Dyson DC37 is a full-size corded bagless cylinder built on Dyson’s Root Cyclone separation platform, delivering high-efficiency dust separation for standard household cleaning across carpet and hard floors. The DC37 sits above the DC33c in Dyson’s corded cylinder range with a larger bin capacity and the same core cyclone-plus-HEPA filtration architecture. The Dyson DC37 uses Dyson’s Root Cyclone separation system to spin incoming debris at high velocity, centrifugally separating large and medium particles from the airstream before they reach the filtration stage, limiting the fine-particle load that accumulates in the downstream pre-motor filter. The fine fraction that passes through cyclone separation, ultrafine dust, airborne particles, and microscopic debris, continues to the pre-motor HEPA filter, where the dense filter media captures these particles and keeps them clear of the motor. Over time, fine-particle build-up narrows the open media structure of the filter, increasing airflow resistance and reducing suction. Rinsing under cold water clears accumulated dust and restores airflow through the media. Allow at least 24 hours to dry completely before reinserting. When rinsing no longer recovers full airflow, a replacement filter returns the machine to specification. Plus.Parts® supplies this pre-motor HEPA filter for the Dyson DC37 as an exact-fit replacement.
