Locate every filter for this platform
Use the model source to locate washable filter assembly specified for this machine code. Rear twist-off washable filter with filter-fit and filter-wash alerts; it requires at least 24 hours of complete air-drying. Do not substitute the filter layout from another Dyson model family.
Inspect before cleaning
Check for heavy dust loading, tears, deformation, odor, moisture, a missing seal, or a filter that will not seat and lock. Replace a damaged or permanently restricted filter rather than forcing it into place.
Wash only a documented washable filter
If the exact guide marks the filter washable, remove loose dust, rinse it with cold water using the documented method, expel excess water without damaging the media, and leave it in a warm, ventilated place for the specified drying period. Do not use detergent, a dishwasher, microwave, dryer, or open flame.
Refit and verify the seal
Install only a completely dry filter in the correct orientation. Confirm its cover closes flush and the filter cannot bypass dust around its edge. Make a short test and stop if airflow, odor, heat, or a filter warning persists.
