About the Dyson DC50
The Dyson DC50 is a compact corded Ball upright. Its pre-motor filter is the washable purple unit at the top of the machine — the filter that guards the motor and needs the most frequent attention on this model.
The DC50 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 gone limp. A tired pre-filter shows as weaker suction and dust on the exhaust.
✓ Buying Advice
Genuine Dyson gives a guaranteed seal; good aftermarket purple filters are inexpensive — just confirm the listing lists the DC50 specifically. A spare lets you keep cleaning while the washed one dries.
⚠ Common Mistakes
The DC50 mistake that harms motors is refitting the filter damp — Dyson specifies 24 hours of air-drying. The second is confusing it with the separate post-motor filter; they are different parts.
