Keep observations local
Say whether fluff is on clothing, the door edge or nearby cabinet. Include a recent filter refit and any drying-result change.
Use model-specific care
Only the matching manual should guide routine filter care. Persistent escape or a changed door fit may need assessment; do not remove internal ducting or apply tape over openings.
A useful distinction
A damaged or poorly seated removable filter may be relevant, but the model determines its correct arrangement. Describe what is visible and keep component replacement separate from an assumption about hidden airflow faults.
