How do I know HP01 purifier is working | Dyson Community
Skip to main content

Is the purifier always on when the fan is on or does it work separately? I don’t see a separate control for just the purifier. Thanks

Hi @Django,

Welcome to the Dyson Community!

Your Dyson purifier is always actively purifying whenever it’s running. All of the airflow pulled into the machine passes through the filter before being projected into the room by the loop amplifier. The HEPA H13 filter captures 99.95% of particles as small as 0.1 microns. A layer of activated carbon also removes odours and gases including VOCs.

Hope this answers your question!
