Quick answer

Replacing the Dyson V8 hepa filter is a DIY job of about 10 minutes. Compatible hepa filters currently start at $6.99. Replace it Every 12 months under normal use. Full step-by-step below.

The V8 post-motor filter sits at the rear of the machine and is washable in most builds, but it clogs and ages more slowly than the pre-filter. Replace it when washing no longer restores airflow — a spent post filter both restricts suction and lets fine dust escape.

About the Dyson V8

The Dyson V8 cordless has a post-motor filter downstream of the motor, in addition to the washable purple pre-motor filter on top. This page covers the post-motor (HEPA-grade) filter — the sealed final stage.

Step-by-Step: Replacing the Dyson V8 HEPA Filter

1
Power off
Switch the V8 off before removing the rear filter.
2
Release the post-motor filter
Locate the filter at the rear of the machine and twist/release it.
3
Remove the old filter
Pull the post-motor filter out.
4
Fit the new (dry) filter
Seat the new filter and lock it; if reusing a washed one, be sure it's fully dry.
5
Test
Power on and confirm normal suction.

⚠ Common mistakes on the V8

The V8 mistake is only ever cleaning the purple pre-filter and never the post-motor one, so allergens build up. The second is refitting either filter damp — 24-hour air-dry, no detergent, no hot water.

✓ OEM vs aftermarket for the V8

Genuine Dyson guarantees the seal that keeps the V8 truly sealed; aftermarket post filters are cheaper and fine when the listing names the V8. Refresh both filters together for a complete reset.

🔁 How often to replace

The Dyson V8 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.
