Confirm the DC31 configuration
DC31 (DC31) is a bagless handheld body with direct-fit cleaning tools. Cataloged variants include DC31, DC31 Motorhead. The verified owner-service profile identifies it as the Dyson DC31 retired handheld family. Match the machine code and serial label before ordering a filter, bin, direct-fit tool, battery where owner-replaceable, or charger; a retail family name can cover incompatible hardware.
Locate every filter for this platform
Use the model source to locate washable filter assembly specified for this machine code. Single washable pre-filter with complete drying required before refitting. 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.
