About the Dyson DC25
The Dyson DC25 is a corded Ball upright. Its pre-motor filter is the washable purple unit at the top of the machine — the primary filter to keep clean for steady suction and to protect the motor.
The DC25 pre-motor filter is washable foam-and-fleece and lifts out from the top. Replace it only when rinsing no longer restores it — grey after washing, torn, or limp. A tired pre-filter shows as weaker suction and dust on the exhaust.
✓ Buying Advice
Genuine Dyson gives a guaranteed seal; aftermarket purple filters are inexpensive — confirm the listing lists the DC25. A spare keeps you cleaning while one dries.
⚠ Common Mistakes
The DC25 mistake that harms the motor is refitting the filter damp — air-dry a full 24 hours. The second is confusing it with the separate post-motor filter.
