Quality genuine Miele part
Easy purchase and been genuine, is a direct replacement. Has given my vacuum back the suction it was starting to lose, despite regular cleaning of old filter. Was purchased with a new anti bacterial filter which is delayed and I'm still waiting on months later. Otherwise would be 5 star review.

The Miele Fine Dust Filter CX FSF is a genuine replacement filter for Boost CX1 vacuums that helps trap very fine dust and support cleaner air while you vacuum. It suits households wanting simple maintenance and reliable fitment, with a washable pleated design that can help maintain suction. Its main limitation is that it only fits compatible Boost CX1 models, not a wider range of vacuums.

Things to consider
This filter is designed specifically for compatible Miele Boost CX1 vacuums, so it is less versatile than universal or multi-model filter options.
Pet owner suitability
7/10 - helpful for households wanting better fine dust capture, but it is not a specialised pet hair attachment.
Surface versatility score
8/10 - supports cleaner airflow across all surfaces your compatible vacuum already handles, though it does not change floorhead performance.
Vacuum model compatibility
Compatible with Miele Boost CX1 vacuums
Ease of attachment
9/10 - straightforward to install and remove as part of routine filter maintenance.
Key benefits
- Fine Dust Filtration: Helps trap very small dust particles from the vacuum air path for cleaner everyday use.
- Pleated Filter Design: Increases surface area to support effective dust capture without a bulky filter shape.
- Washable Construction: Can be cleaned by tapping or rinsing to help extend usable life before replacement is needed.
- Genuine Miele Accessory: Designed for proper fit and compatibility with Boost CX1 vacuum cleaners.
- Easy Installation: Simple to remove and refit during routine vacuum maintenance.
- Suction Maintenance: Helps restore airflow and cleaning performance when replacing an old or clogged filter.
- Compact Filter Format: Fits neatly into the vacuum without adding unnecessary bulk.
- White Finish: Matches the original vacuum interior styling for a consistent look.
Q: Does this filter fit every Miele vacuum or only Boost CX1 models?
A: No. Miele Fine Dust Filter CX FSF is listed for Boost CX1 vacuums only. It is not a universal Miele filter, so buyers with another Miele range should match the vacuum model first rather than relying on a similar shape.
Q: Is this a genuine Miele replacement or a third-party compatible filter?
A: This is a genuine Miele replacement filter for compatible Boost CX1 vacuums. That matters if you want the intended fit and airflow path of the original part, rather than a generic substitute made to suit multiple vacuum ranges.
Q: Can the filter be washed, or does it need replacing each time?
A: The filter can be cleaned by tapping or rinsing, so it is not designed as a single-use part. Regular cleaning helps maintain airflow, but a worn or heavily clogged filter will still need replacement when cleaning no longer restores performance.
Q: Will replacing an old fine dust filter improve suction again?
A: Yes. A fresh Miele Fine Dust Filter CX FSF can help restore airflow when the old filter is clogged with fine dust. It will not fix suction loss caused by a blockage elsewhere in the vacuum or by an unrelated fault.
Q: Is Miele 11639250 a direct replacement for the original CX FSF?
A: Yes. Miele 11639250 is the Fine Dust Filter CX FSF for compatible Boost CX1 vacuums, so it suits buyers replacing the original like-for-like part. It is a vacuum filter only, not a floorhead or a different filter type in the range.
