Air Treatment - Autoreact buzzing. Is this normal?

  • 4 June 2023

I bought my cool auto react purifying fan - everything works brilliantly. But when it’s plugged in and inactive it emits a notable humming sound which is quite annoying - especially at night. Is it meant to do that?  Is that a sign that it’s actually doing / monitoring something and not altogether inactive at all?

It could be the continuous monitoring, have you tried switching that off? Using Continuous monitoring | Dyson Community

Hello @Alison Gaskins 

Thanks for reaching out. It's always nice to see our members engaging. I thought I'd just step in and add to the information given. 

When continuous monitoring is active, and when the machine is in a standby state, users may hear a low humming sound. This is caused by the onboard sensors. 

I have added the following link for further information and guidelines on this here
