Coway AirMega 400 sleep mode cannot be turned off
Again, I think it's the way the Airmega 400 is designed (albeit counterintuitive). The highest and second highest airflow speeds/settings wouldn't be night mode anyways. The purpose of any night or sleep mode on a purifier is to reduce light output and run on a very quiet speed.
