Please listen to video. It’s very loud. Brand new out of the box it makes this horrible noise more so on mid to low speeds. Yes I done the standard troubleshooting per Dyson. This noise seems to be common among the whole purifier line up? This would be a good unit for Dyson engineers to get a hold of and find the cause. I purchased it as Best Buy.

Hi @Brent1980
This is a notably different noise compared to the one made by my machine.
The onboard sensors will calibrate out of the box, anywhere up to one hour of use. If it doesn’t stop after this time, try turning off the continuous monitoring. This function collects environmental information, even why in standby. This feature is active at all times.
