The Dyson DC37 is a bagless cylinder vacuum built around Root Cyclone multi-cyclone technology, a system that uses twelve cyclones working in parallel to separate debris from the airstream before it reaches the motor. The post-motor HEPA exhaust filter handles the residual fraction: the fine particles the cyclones do not fully capture, including pollen, pet dander, and fine household dust. That filter processes every cubic metre of air the DC37 moves in daily use, and its loading accumulates gradually across sessions. Washing restores much of its airflow capacity, but each cycle recovers slightly less than the last; when suction noticeably drops between washes, the filter has reached its replacement point.
This set provides three Plus.Parts® washable HEPA filters, each a direct-fit match to the DC37 exhaust housing. They seat and secure identically to the original Dyson filter, with no tools or adapters required. With three units in the pack, one filter can be drying after a wash while another is already installed, removing any gap in service over the course of a full maintenance cycle. Standard care: rinse under cold water, tap out excess moisture, and allow at least 24 hours to dry completely before refitting.
