Frequently asked questions

How often should I clean the filter?

To maintain optimum performance, your Dyson Supersonic™ professional hair dryer needs regular care and maintenance. We recommend cleaning the filter once a month, or when the three white LED lights flash continuously.

What's the length of the guarantee?

Your Dyson Supersonic™ hair dryer is guaranteed for two years.

Can the Dyson Supersonic™ professional hair dryer dry hair fast even though it doesn’t use extreme heat?

Yes. That’s because it doesn’t rely on heat alone to dry hair. A high-speed, high pressure airflow can achieve fast drying with less reliance on heat.

Can I use my hair dryer when travelling to countries with different electrical voltages?

Your hair dryer has been precisely engineered for fast drying and styling at the voltage of the country in which it was purchased. This allows it to perform optimally. As voltage varies from country to country, please follow the guidance on usage in the guarantee section of your user manual.

Will the new attachments work with my current Dyson Supersonic™ hair dryer?

Yes, the new attachments are fully compatible with older generations of Dyson Supersonic™ professional hair dryers.

Can I buy the consumer Dyson Supersonic™ hair dryer as a professional stylist to use in my salon?

In salon environments filters can clog more quickly with hairspray, so it’s best to use a Dyson Supersonic™ professional hair dryer where the heavy-duty filter has been designed to meet the needs of a busy salon. The consumer warranty doesn’t cover use in commercial environments, or if it’s used for more than two hours a day.
