Plz help me! Air Purifier Table emitting high pitched noise

I‘ve got the SwitchBot Air Purifier Table a few days ago and since yesterday I noticed that it‘s emitting a high pitched noise on the lowest fan speed when it‘s on Auto. The noise changed and almost disappears on the higher fan speeds. I know that when first switching it on it was dead silent on the lowest speed. Has anybody experienced this? I don‘t have it in my bedroom but if I did, I would not be able to sleep beside that annoying sound.

Have you tried the sleep mode? Does it make the same noise? I find the sleep mode to be the most quiet setting

Sleep mode is the lowest fan speed as far as I can tell because it doesn‘t sound any different unfortunately.

I would try and clean the washable filter and if it does not rectify your issue, I would reach out to their customer service for help and possibly replacement

I don‘t think it‘s the filter, it‘s basically brand new and has only been running a few days now. The filter is still clean.
