Quick answer

Replacing the Dyson DC25 hepa filter is a DIY job of about 10 minutes. Compatible hepa filters currently start at $13.90. Replace it Every 12 months under normal use. Full step-by-step below.

The DC25 post-motor filter is washable in most builds and sits apart from the top pre-filter. Replace it when washing no longer restores it or the media is damaged; a tired post filter restricts airflow and lets fine dust through.

About the Dyson DC25

The Dyson DC25 is a corded Ball upright. Alongside the washable pre-motor filter, it has a post-motor filter that cleans the air leaving the machine — the finer, sealed stage this page covers.

Step-by-Step: Replacing the Dyson DC25 HEPA Filter

1
Power off and unplug
Disconnect the DC25 from the wall first.
2
Locate the post-motor filter
Find the post-motor filter housing (separate from the pre-filter lid); release it.
3
Remove the old filter
Lift out the post-motor filter unit.
4
Fit the new (dry) filter
Seat the new filter so it locks flush; if reusing a washed one, be sure it's fully dry.
5
Close and test
Refit the cover, plug in and confirm suction.

⚠ Common mistakes on the DC25

The DC25 mistake is servicing only the pre-motor filter and forgetting the post-motor one — both need care. The second, with any Dyson washable filter, is refitting it damp: air-dry a full 24 hours.

✓ OEM vs aftermarket for the DC25

Genuine Dyson gives a guaranteed seal; aftermarket HEPA-style filters are cheap and fine when the listing names the DC25. Refresh both filters together for a full reset.

🔁 How often to replace

The Dyson DC25 hepa filter should be replaced Every 12 months under normal use — sooner with pets or daily heavy use. Signs it's due: Reduced suction, musty odor.
