Frequently Asked Questions

How often should I clean my Dyson filter?

Dyson recommends washing the filter at least once a month. Pet owners or heavy users should wash it every two weeks.

Can I speed up drying the filter with a hairdryer?

No — Dyson advises against using any heat to dry the filter. Heat can distort the filter material. Air drying at room temperature is the only safe method.

My Dyson filter alert is still on after washing and drying — what do I do?

If the alert persists with a clean dry filter, try resetting the machine by switching it off and back on. If still lit, the filter may be damaged and needs replacement.
