Dyson DC39 – Plus.Parts® Spare Washable HEPA Pre-Filter

Compact and manoeuvrable, the Dyson DC39 belongs to Dyson’s bagless cylinder family as a practical mid-range model built around consistent suction rather than headline-grabbing specifications. Its airpath channels suction from the floorhead through the cyclone bin and into the motor, with the HEPA pre-filter sitting between the bin and motor to intercept the particles the cyclone separator does not retain by density alone. That filter position makes it a regular maintenance point on the machine: it loads steadily with fine dust and allergens in normal use, and a filter running past its rinse interval gradually chokes the airflow the motor can produce. On a compact cylinder like the DC39, the drop in available suction is noticeable before the bin signals it needs emptying.

This spare filter contains a Plus.Parts® washable HEPA element, sized to the DC39’s original filter housing. It seats without adjustment and follows the same maintenance cycle as the original: cold rinse, 24 hours to dry, and the vacuum is back at full airflow performance.

The media retains its shape and filtration density through repeated washing cycles, making it a lasting replacement rather than a short-term measure. For fit or delivery questions, our team responds personally and promptly.
