Clicking sound at night

I agree with the two previous low rating reviews that the locking sound even at the night mode or lowest fan mode is really annoying! It wakes me up! I plan to return it!
This is my favorite brand and favorite model! Beautiful, quite efficient. The only thing that would make it better is if the light could completely shut off at night so I could keep it in my bedroom at night. There is always some light emitted. Perfect for the living room though.
As you can see in the video, the unit is whisper-quiet at night. It has replaced an Austin Air Bedroom Machine that was much, much louder even on the Low setting. I can now sleep better, thanks to BlueAir's quiet but effective filtration. I also like the ability to auto-schedule Night mode on/off through the app. (E.g. On daily at 8pm and Off, turning to Auto, at 8am.)
