How to Replace Dyson V8 HEPA Filter (Step-by-Step Guide)
Replacing the Dyson V8 hepa filter is a DIY job of about 10 minutes. 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.

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