Product details
The F71 cyclonic filter, part 440002674, is built for the Dirt Devil UD70115. It is supplied with its foam component and sits inside the cyclone chamber where the vacuum separates dust from the airstream before it ever reaches the main filtration stage.
Fits the Dirt Devil UD70115. A cyclonic filter in this position takes on the heaviest, coarsest debris a vacuum picks up, so it loads faster than filters further downstream. Once the foam and mesh are packed with fine dust, the cyclone loses separation efficiency and pushes more of that debris on toward the next filter stage instead of spinning it out of the airflow.
Suction that drops noticeably even right after emptying the dirt cup is the usual sign this filter needs attention. Tap or rinse it clean first if it is a washable style for your model, and let it dry fully before reinstalling, since foam packed with trapped moisture will restrict flow the same way clogged dust does.
- Part: 440002674, cyclonic filter with foam
- Fits: Dirt Devil UD70115
- Position: inside the cyclone chamber, ahead of the main filter stage
- Replace when: suction drops soon after emptying the dirt cup, or the foam stays gray after cleaning
Judge the foam as carefully as the filter body when deciding whether to replace, since foam that has collapsed, torn, or gone permanently gray will keep passing fine dust downstream even while the filter body itself still looks serviceable.
