Product Description

The Dyson DC25 post filter door (part number 915447-06) is the original filter compartment cover assembly for Dyson DC25 upright vacuums. This critical component seals the post-motor filter chamber and maintains proper airflow and suction during operation. Designed specifically for DC25 models.

This is a genuine Dyson OEM part manufactured to exacting specifications. The post filter door ensures the filter chamber remains sealed, preventing unfiltered air from bypassing the post-motor filter. Replacement may be needed if the door warps, cracks, or no longer seals properly.

The DC25 is a full-size upright vacuum with motorized brush roll technology. This part is not compatible with other Dyson DC series models (DC40, DC33, DC65) or V series cordless vacuums, as Dyson does not cross-reference filter doors between model lines.

Use Case

If your Dyson DC25 upright is losing suction, producing a rattling noise from the filter area, or you notice visible damage to the filter door, this replacement part restores the sealed filter chamber. The post filter door prevents unfiltered air from re-entering the motor, protecting internal components and restoring full cleaning power. This is essential maintenance for any DC25 owner experiencing filter-related issues or repairs.
