About the Dyson Ball Animal 2

The Dyson Ball Animal 2 is a corded upright built for pet homes. 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 with pets.

Step-by-Step: Replacing the Dyson Ball Animal 2 Pre-Motor Filter

1
Power off and unplug
Disconnect the Ball Animal 2 before opening the filter lid.
2
Open the filter lid
Lift the lid on top of the machine to reveal the purple pre-motor filter.
3
Remove the old filter
Lift the purple filter out, tipping it away so dust doesn't fall back in.
4
Insert the new (dry) filter
Seat the new filter flat; if reusing a washed one, confirm it's completely dry.
5
Close and test
Click the lid shut, plug in and check suction.

⚠ Common mistakes on the Ball Animal 2

The Ball Animal 2 mistake that harms the motor is refitting the filter damp — Dyson specifies 24 hours of air-drying. The second is confusing it with the separate post-motor HEPA; they're different parts.

✓ OEM vs aftermarket for the Ball Animal 2

Genuine Dyson gives a guaranteed seal; aftermarket purple filters are cheap and fine when the listing names the Ball Animal 2. A spare keeps you cleaning while one dries.
