I have had this for a few months now, and I absolutely love Coway Airmega 250S Air Purifier. It looks awesome and stylish, with a modern yet retro look. This smart air purifier is basically silent most of the day until it detects something in the air. It quickly ramps up to high speed, and the fan isn’t too loud.
